Toshiba announces power-saving, miniature photorelays
Toshiba Electronics Europe has launched a new series of semiconductor photorelays that offers longer service life, lower power consumption and reduced board space requirements than mechanical alternatives for a wide variety of switching applications.
Supplied in a compact SOP4 surface-mount package, the new TLP170 photorelays measure just 4.4mm x 3.9mm x 2.1mm. Each device comprises a gallium arsenide (GaAs) infrared emitting diode that is optically coupled to a MOSFET. The relays help to lower power consumption thanks to an improved output photodiode array, which has reduced maximum LED trigger current from the 3mA of previous devices to just 1mA.

Devices in the TLP170 series offer off-state voltages of 60V, 200V, 350V and 600V, allowing the series to satisfy a wide range of requirements. Potential applications range from security and measurement equipment to home appliances, office equipment, telecommunications products and factory automation.

All of the new photorelays feature a normally open (1-Form-A) configuration and a minimum isolation voltage of 1500Vrms. Depending on the device chosen, maximum on-state current and on-state resistance ranges from 90mA to 400mA and 60Ω to 2.0Ω respectively. Maximum turn-on time for all of the relays is 8.0ms, with maximum turn-off time specified as 3.0ms.
