TLP350F(D4-TP4,F) – Gate Driver Photocoupler – Toshiba

About this part

The Toshiba TLP350F(D4-TP4,F) is a high-speed gate drive photocoupler designed for directly driving IGBTs and power MOSFETs in industrial power-conversion equipment. It integrates a GaAlAs infrared LED optically coupled to a high-gain photo-IC detector with a totem-pole output stage capable of ±2.5 A peak output current, enabling robust turn-on and turn-off of medium-power switching devices. The “(D4)” option designates VDE approval per DIN EN 60747-5-2, and the F-type lead form provides a gull-wing surface-mount footprint supplied on tape and reel.
