Description

The FDS3890 is a PowerTrench® dual N-channel MOSFET designed specifically to improve the overall efficiency of DC-to-DC converters using either synchronous or conventional switching PWM controllers. This 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-to-DC power supply designs with higher overall efficiency.
Fast switching speed
High performance Trench technology for extremely low RDS (ON)
High power and current handling capability
±20V Gate to source voltage
4.7A Continuous drain current
20A Pulsed drain current
