Medium voltage, high current photorelay in compact package

A new photorelay in a small 2.54SOP4 package that is just 2.1mm high with a 2.54mm pitch has been launched by Toshiba Electronics Europe. Fabricated using the latest U-MOS VIII trench MOSFET process, the new TLP3145 combines an off-state output terminal voltage of 200V with a controllable on-state current of up to 0.4A continuously or 1.2A when pulsed.

This makes TLP3145 a suitable replacement for a 1A mechanical relay that is used to control a 100VAC circuit.

Replacing a mechanical relay with a photorelay that is smaller and does not need a relay driver increases system reliability and supports space-saving design.

The TLP3145 is conveniently rated for an operating temperature range of -40 to 110ºC, making it easier to allow for a temperature margin in system-level thermal design.

The TLP3145 turns on or off in just 0.5ms (max.) and consumes a max. of 1μA in its OFF-state.

The new device offers an isolation voltage of 1,500Vrms and is approved to the UL1577 safety standard.
