Toshiba Electronics Europe (TEE) has announced a new series of photorelays that provide a minimum input-to-output isolation voltage of 5000Vrms (AC, 1 min) for reinforced insulation. Devices in the TLP220 series are supplied in a compact DIP4 package that measures just 7.6mm x 4.6mm x 3.7mm. Clearance and creepage distances are 7mm as standard.
The new photorelays suit designs where engineers want to replace a mechanical relay with an optically-isolated part to meet reinforced insulation safety requirements. Target applications will include smart meters, factory automation systems, test and measurement equipment, security systems and gaming and entertainment products.
