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.

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.
When connected in series with a power source, the OSP5050 high side OR-ing FET controller is used in conjunction with an external NMOSFET as an ideal diode rectifier. This OR-ing controller allows MOSFETs to replace diode rectifiers in distribution networks, thereby reducing power loss and voltage drop.

Electronic Water Pumps & Electronic Oil Pumps & Fan Drivers
An electronic water pump is a liquid transfer device driven by an electric motor (brushless or brushed), which enables precise regulation of flow rate, head pressure and on/off status via an electronic control unit (ECU). It is widely used in scenarios including automotive engines, cooling systems of hybrid/ battery electric vehicles, home appliances and industrial equipment. Compared with traditional mechanical water pumps, it realizes full electronization from power source to control system, allowing the pump’s operating status to be adjusted in real time according to cooling demands, thus significantly improving energy efficiency and reducing noise levels.
In new energy vehicles (including battery electric vehicles, hybrid electric vehicles and fuel cell vehicles), motor controllers, power electronic modules and battery packs generate substantial amounts of heat. To ensure the reliable operation of these critical components, the on-board cooling system must provide sufficient heat dissipation capacity, and the fan driver serves as the core execution unit for air cooling or air-liquid hybrid cooling systems. It matches the motor speed with heat dissipation requirements through variable frequency speed regulation, delivering a highly efficient, adjustable and low-noise thermal management solution.

Design Features
Electrification & Active ControlStepless speed regulation is achieved via the electronic control unit (ECU). The system can precisely regulate the rotational speed and flow rate of the water pump according to heat dissipation demands, realizing on-demand supply to achieve the goal of high efficiency and energy conservation.
High Reliability, Long Service Life & Low NoiseThe designed service life is equivalent to that of the entire vehicle, which is far longer than that of traditional mechanical water pumps. Without the masking effect of internal combustion engine noise, the operating noise of the electronic water pump itself becomes prominent, thus imposing extremely high requirements on noise reduction design.
