Shindengen Launched High Withstand Voltage 900V Power MOSFET P4F90VX3 and P7F90VX3, Reducing Required Snubber Circuits and Optimal for Flyback Circuits
SHINDENGEN Electric Manufacturing Co., Ltd. has launched the P4F90VX3 and P7F90VX3 power MOSFET for white goods and industrial devices. The products' high withstand voltage of 900V increases the degree of freedom of power supply design while also making it possible to reduce the number of required snubber circuits.
Overview
Flyback circuits are often used in control power supplies for white goods such as refrigerators and washing machines, as well as in industrial devices. There are 800V withstand voltage class MOSFET available on the market aimed at flyback circuit switching elements for worldwide input, however, there has been a demand for higher withstand voltage MOSFET in order to secure greater design margins and reduce the number of components.
The 900V withstand voltage of these new products is aimed at satisfying market demand for widening the design margin for control power supplies composed of flyback circuits, and also allowing for a reduction of the number of snubber circuits used to protect the MOSFET from the surge voltage that occurs in these applications.
In addition, the input capacitance (Ciss) for these products is low, allowing for the improvement of power supply light load efficiency by 1.7%*1.
The products use the FTO-220AG (JEITA: SC-91) through-hole type packages which are often used for control power supply boards, and there are also plans to add surface-mounted types to the lineup going forward.
*1: Compared to equivalent products from other companies.
Features
1. High withstand voltage VDSS 900V
The withstand voltage of 900V increases the degree of freedom of power supply design and also makes it possible to reduce the number of snubber circuits required to protect the MOSFET from surge voltage.
2. Low input capacitance (Ciss) 610pF (P4F90VX3)
The low Ciss characteristics improve power supply efficiency during light loads by 1.7% (Fig. 1).
3. High breakdown voltage
100% Avaranche, di/dt inspection
4. FTO-220AG (JEITA: SC-91) package
Utilizes the through-hole type packages used by many control power supply boards.
Typical Applications
Control power supplies for white goods (Refrigerator, washing machine) (Flyback circuit)
Control power supplies for industrial devices (Flyback circuit)
Fast discharge circuit switches
High voltage relays
