Toshiba Electronic Devices & Storage Corporation Releases Small Active-Clamp MOSFET for Relay Drivers

TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation (TDSC) today announced the launch of “SSM3K357R,” a new MOSFET that adopts an active-clamp structure with a built-in diode between the drain and gate terminals. The device is suited to driving inductive loads, such as mechanical relays. Volume shipments start today.

The SSM3K357R protects drivers against damage from voltage surges, such as back-EMF caused by inductance. It integrates a pull-down resistor, series resistor and Zener diode, which helps reduce the part count and save on board space.

An industry-standard SOT-23-class package, a low operating voltage of 3.0V and AEC-Q101 qualification make the SSM3K357R suitable for automotive and many other applications.

Applications

Relay and solenoid control for automotive
Relay and solenoid control for industry
Clutch control for OA equipment

Features

Active clamp structure suitable for driving an inductive load
Low operating voltage of 3.0 V
AEC-Q101 qualified
