Medium voltage, high current photorelay in small package from Toshiba

A photorelay in a 2.54SOP4 package that is 2.1mm high with a 2.54mm pitch, has been launched by Toshiba Electronics Europe.

Fabricated using the U-MOS VIII trench MOSFET process, the TLP3145 is said to combine 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. Toshiba says this makes it suitable replacement for a 1A mechanical relay that is used to control a 100V AC circuit.

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

The device turns on or off in just 0.5ms (maximum) and is designed to consume a maximum of 1μA in its OFF-state. It also offers an isolation voltage of 1500Vrms and is approved to the UL1577 Safety Standard, Toshiba adds.
