TLP155E(V4-TPL,E) – Gate Driver Coupler – Toshiba

The Toshiba TLP155E is a high-speed photo-IC output photocoupler for direct gate driving of IGBTs and power MOSFETs, featuring 3750 Vrms isolation and +/-15 kV/us common-mode transient immunity in a compact SO6 package.

The Toshiba TLP155E(V4-TPL,E) is a high-speed gate-drive photocoupler that combines an infrared emitting diode (IRED) with an integrated high-gain, high-speed photo-IC detector. Designed for the direct gate driving of IGBTs and power MOSFETs, it delivers a buffer-logic totem-pole (push-pull) output with a peak output current of +/-0.6 A (max). The photodetector incorporates an internal Faraday shield that provides a guaranteed common-mode transient immunity of +/-15 kV/us (min), making it well suited to noisy power-switching environments. The “V4” designation identifies the VDE-approved option (EN 60747-5-5 / EN 62368-1), supplied here in tape-and-reel (“TPL”/”TPR”) form.
