TLP705 is a photocoupler product launched by Toshiba. This product is suitable for IGBT or power MOS FET gate drive circuit. The product has a 50% smaller volume and meets the safety standard reinforced insulation class, so the mounting area in safety standard required equipment can be reduced.
This document describes the Toshiba TLP705 GaAs photocoupler, a 6‑lead SDIP device used for gate‑driving IGBTs and power MOSFETs. It lists the electrical characteristics, maximum ratings, isolation and switching performance, as well as mechanical dimensions and recommended operating conditions.
The datasheet also includes safety and usage restrictions, noting the device’s UL1577 certification, isolation voltage requirements, and handling precautions for static electricity and GaAs material safety.
