Toshiba Electronic Devices & Storage Corporation Releases Small Dual MOSFET for Relay Drivers

TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation today announced the launch of “SSM6N357R,” a new MOSFET 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.

SSM6N357R integrates a pull-down resistor, a series resistor and a Zener diode, which reduces the parts count and save on board space. Furthermore, since it is a dual-type package product (2 in 1), it has an approximately 42% smaller mounting area than the alternative of using two SSM3K357R (2.4 x 2.9 x 0.8 mm) single-type package products.

An industry-standard TSOP6F-class package, a low operating voltage of 3.0V and AEC-Q101 qualification make the SSM6N357R suitable for automotive and many other applications.


  • Relay and solenoid control for automotive applications
  • Relay and solenoid control for industrial applications
  • Clutch control for OA equipment


  • Reduced board space and part count (pull-down resistor, series resistor and Zener diode integrated.)
  • Low operating voltage of 3.0 V
  • Dual package (2 in 1)
  • AEC-Q101 qualified
