All products

The company's main products include the GreenMOS series of Super Junction MOSFETs, SFGMOS and FSMOS series of Shielded Gate MOSFETs, TGBT, SuperSi²C MOSFETs, SuperSi MOSFETs and SiC MOSFETs. These products are widely applicable to industrial and automotive-grade application scenarios, represented by new energy vehicle DC charging piles, on-board chargers (OBC), photovoltaic inverters, energy storage systems, 5G base station power supplies, telecom power supplies, data center server power supplies, industrial lighting power supplies, power tools, intelligent robots, unmanned aerial vehicles (UAV) and UPS power supplies. They are also used in consumer electronics applications such as PC power supplies, adapters, TV power boards, fast chargers for mobile phones and electromagnetic heating products.

In order to meet the demand of high efficiency and minification of power supply system, Oriental Semiconductor has launched a new GreenMOS series of high voltage MOSFET, which adopts unique patented device structure and manufacturing process. GreenMOS product has faster switching speed and softer switching curve than conventional MOSFET, which can greatly restrain switch oscillation while obtaining extremely low dynamic loss. It can not only greatly improve system efficiency and reduce heating, but also simplify system EMI design.

Oriental Semiconductor’s SFGMOS Series MOSFET adopts Semi-Floating Gate structure, which combines the advantages of traditional planar structure and SGT structure of power MOSFET, and has the advantages of higher process stability and reliability, faster switching speed, smaller gate charge and higher application efficiency. SFGMOS Series MOSFET products cover the whole series of 20V~200V, which can be widely used in motor driver, synchronous rectification, etc.

Oriental Semiconductor's IGBT chips adopt a unique Trident-Gate Bipolar Transistor (TGBT) device structure to achieve lower on-state voltage drop and reduced switching losses.Multiple series of first and second-generation TGBT products have been successively launched, covering voltage ranges from 600V to 1700V. These products are suitable for applications such as photovoltaic energy storage inversion, DC charging piles, automotive main drive, OBC, and UPS. Additionally, Oriental has developed an ultra-high-speed series TGBT with an operating frequency of 60-100 kHz, which meets the demands of further high-frequency power systems while delivering higher efficiency.

Trench MOSFET: Reliable and Trustworthy Performance Through extensive development，we continuously expand our product portfolio with advanced small signal MOS and power MOS solutions. Our comprehensive product portfolio provides the flexibility needed in today's market, easily choose the product that best suits for you. Our leading technology ensures the highest reliability and performance, while advanced packaging enhances resistance and thermal performance while reducing size and costs.

Advanced power modules, including IGBTs, MOSFETs, SiC, Si/SiC hybrid modules, diodes, SiC diodes, and intelligent power modules. IGBT modules are used in applications such as main drive and DC-AC class solar inverters, energy storage systems, uninterruptible power supplies, and motor drives. MOSFET modules are used in automotive motor drives and on-board charger applications, with voltage ratings of 40 V, 60 V, 80 V, and 650 V, and use super-junction technology and inductive resistors.

Third-generation semiconductor material power devices are one of the important components of high-performance power devices in the future. The R&D team of Oriental has rich experience in wide bandgap semiconductor research and has developed a series of SiC MOSFETs.

Gallium Nitride High Electron Mobility Transistors (GaN HEMT) are increasingly becoming the choice for mainstream markets. For various high-voltage and low-voltage application scenarios, GaN HEMTs offer the fastest switching capabilities (with the highest dv/dt and di/dt) and superior energy efficiency performance. In addition, the self-developed GaN HEMTs by Oriental Semiconductor Co., Ltd. have reduced conduction losses and switching losses through innovative designs, further improving power density.

Targeting core application scenarios including high-end AC-DC, DC-DC industrial power supplies and AI computing power supplies, Oriental Semi continuously iterates and launches dedicated digital power control ICs, which are fully compatible with high-frequency wide-bandgap power devices and high-density power supply architectures. Compared with traditional analog power ICs, dedicated digital control ICs deliver disruptive advantages. They eliminate the pain points of analog solutions, such as parameter calibration relying on resistors and capacitors, cumbersome debugging and rigid design schemes. Key parameters can be digitally configured, allowing flexible tuning of loop compensation, operating topologies, various protection thresholds and light-load energy-saving strategies. Multiple types of power products can be supported without modifying hardware circuits.

To meet diverse power management requirements ranging from portable devices to industrial high-voltage control systems, Oriental Semi Devices has released a full lineup of high-performance LDO products. This portfolio includes ultra-low-power CMOS architecture and high-reliability Bipolar architecture. Adopting advanced bandgap reference and over-current protection technologies, these regulators feature a wider input voltage range and excellent cost performance compared with traditional regulators. The CMOS series achieves a quiescent current as low as 0.2 μA and a power supply rejection ratio (PSRR) up to 90 dB. The Bipolar series supports large output current up to 1.5 A and withstands voltages above 36 V. It maintains high output voltage accuracy while greatly simplifying peripheral circuit design. The product family covers an input voltage range from 5.5 V to 100 V, with multiple current ratings from 100 mA to 1.5 A. A variety of package options are available, including SOT23, SOT89, SOT223 and TO252, to satisfy power supply demands of various complex systems.

To address the stringent requirements of modern electronic systems for low power consumption, high precision and high-speed signal processing, Oriental Semi Devices has launched a full portfolio of high-performance analog signal chain products based on Operational Amplifiers (OPAs). This product lineup consists of four core categories: low-voltage general-purpose op-amps, high-voltage general-purpose op-amps, low-voltage high-speed op-amps and low-voltage comparators. Built on advanced semiconductor processes and optimized internal topologies, these devices feature a wider supply voltage range, extremely low input offset voltage (Vos) and superior power supply rejection ratio (PSRR) compared with conventional counterparts. The low-voltage general-purpose series achieves a quiescent current as low as 50 μA and supports rail-to-rail input and output. The high-speed series delivers a gain bandwidth product up to 250 MHz and a slew rate of 180 V/μs. It maintains ultra-low noise while greatly enhancing the dynamic response of the system.

Our DSP products focus on front-end chip design. We independently own the IP source code for DSP processor cores and all peripheral modules. With years of accumulation, we have built a comprehensive portfolio of design resources including IP cores, design flows, automation scripts and chip architectures, enabling fully independent development of core IP throughout the entire process. Centering on key technologies for DSP chip design, we have filed 11 invention patents (4 granted), 17 software copyrights and 3 integrated circuit layout designs. Our products are now in mass production and serve many well-known domestic enterprises.
