TOSHIBA Photocoupler GaAℓAs IRED + Photo IC

TLP351

Inverter for Air Conditioner

IGBT/Power MOS FET Gate Drive

Industrial Inverter

The TOSHIBA TLP351 consists of a GaAℓAs light emitting diode and a

integrated photodetector.

This unit is 8-lead DIP package.

TLP351 is suitable for gate driving circuit of IGBT or power MOS FET.

Especially TLP351 is capable of “direct” gate drive of lower Power

IGBTs.
