High-voltage MOSFETs

31 March 2010 Power Electronics / Power Management

ON Semiconductor has expanded its power switching product offering with the introduction of a high-voltage power MOSFET portfolio including 500 V and 600 V devices.

These new solutions are designed for the robust needs of high-voltage energy conversion applications such as power factor correction (PFC) and pulse width modulation (PWM) stages, where faster turn-on and reduced dynamic power losses are crucial. Specifically, they are well suited for use in power adapters for gaming, printing and notebooks, as well as implementation in ATX power supplies, LCD panel power and industrial lighting ballast.

The new 500 V and 600 V devices are single N-channel MOSFETs offering minimised power dissipation by delivering low RDS_(on). They employ planar stripe technology, allowing operation in the most demanding applications. The avalanche energy ratings on these devices offer robust operation in power supply applications.
