500-V MOSFETs offer benefits of 650-V chips

The new Vishay Siliconix SiHx25N50E 500 V MOSFETs are a new family that feature the same benefits of conduction and switching losses as the company's 600 V and 650 V E series devices. The devices are built on second-generation super junction technology will target saving energy in consumer products, lighting applications, and ATX/silver box PC switch mode power supplies.

The 25 A MOSFETs feature 145 mΩ on-resistance in a variety of package options, including the TO-220 (SiHP25N50E), TO-247AC (SiHG25N50E), and the thin leaded TO-220 FULLPAK (SiHA25N50E). They provide a gate charge of 57 nC. The on-resistance and optimized switching speed of the 500 V technology can increase efficiency and power density in power factor correction (PFC), two-switch forward converter, and flyback converter applications.
