Two halogen-free photorelays have been introduced by Toshiba, offering minimum isolation voltage of 3750VRMS. The TLP172AM and TLP172GM are housed in 4-pin SO6 packages that can operate at a maximum temperature of +110°C. Both products can be used to replace mechanical relays and are suited to designs demanding high-performance switching, electrical isolation and extended temperature operation.
Potential applications include factory automation, Battery Management Systems (BMS), telecommunication equipment and the IoT.
The photorelays utilise 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.
