STD35NF06L

N-channel 60 V, 0.014 Ω, 35 A STripFET™ II Power MOSFET

in a DPAK package

Datasheet — production data

Features

■Low threshold drive

■Gate charge minimized

Applications

■Switching application

Description

This Power MOSFET has been developed using

STMicroelectronics’ unique STripFET process,

which is specifically designed to minimize input

capacitance and gate charge. This renders the

device suitable for use as primary switch in

advanced high-efficiency isolated DC-DC

converters for telecom and computer applications,

and applications with low gate charge driving

requirements.
