New medium voltage, high current photorelay in small package

Toshiba Electronics Europe has launched a new photorelay in a small 2.54SOP4 package that is just 2.1mm high with a 2.54mm pitch. Fabricated using the latest U-MOS VIII trench MOSFET process, the new TLP3145 mixes 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 the device a suitable replacement for a 1A mechanical relay that is used to control a 100VAC circuit. The device is conveniently rated for an operating temperature range of -40C to +110C, making it simpler to allow for a temperature margin in system-level thermal design. The device turns on or off in just 0.5ms (max) and consumes a max of 1µA in its OFF-state. The new device enables an isolation voltage of 1500Vrms and is approved to the UL1577 Safety Standard.
