Photorelays deliver 3.75kV of isolation up to 110°C

November 07, 2016 // By Julien Happich
Toshiba Electronics Europe's halogen-free photorelays TLP172AM and TLP172GM guarantee a minimum isolation voltage of 3750Vrms from 4-pin SO6 packages.

Rated for operation at up to 110°C, the devices can replace mechanical relays in factory automation, battery management systems (BMS), or telecommunication equipment. The photorelays use multi-chip technology and were developed as high specification, pin-compatible versions of Toshiba’s existing 2.54SOP package products, the TLP172A and TLP172G. A double-mould structure improves minimum voltage isolation to 3750Vrms against the 1500Vrms of existing products.
