100V Dual N-Channel PowerTrench® MOSFET
General Description
These N-Channel MOSFETs have 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.
Features
3 A, 100 V.
RDS(ON) = 125 m@ VGS = 10 V
RDS(ON) = 135 m@ VGS = 6 V
Fast switching speed
Low gate charge (14 nC typ)
High performance trench technology for extremely
low RDS(ON)
High power and current handling capability
