FDS3812
80V N-Channel Dual MOSFET

This N-Channel MOSFET has been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers.

These MOSFETs feature faster switching and lower gate charge than other MOSFETs with comparable RDS ON specifications. The result is a MOSFET that is easy and safer to drive even at very high frequencies , and DC/DC power supply designs with higher overall efficiency.

A, 80 V.

RDS ON = 74 VGS = 10 V RDS ON = 84 VGS = 6 V
• Fast switching speed
• Low gate charge 13nC typ
• High performance trench technology for extremely low RDS ON
• High power and current handling capability
