High-current photorelay for test and control applications
Photorelays provide fast switching speed, high reliability, lower power consumption, and noise-free operation in a space-saving package, making them an alternative to mechanical relays. Consisting of a photo MOSFET optically coupled to an infrared light emitting diode, the new photorelay uses the latest generation trench MOSFET to realise an approximately 1.4 times higher on-state current than Toshiba’s existing product, the TLP3103. This performance, combined with a 3.3A (max.) output, will accelerate the replacement of mechanical relays in applications that require high density assembly. Replacing a 3A-capable DIP package with the 2.54SOP6 package reduces the assembly area by 40%, and the overall product height by half. Other features include trigger LED current of 3 mA (max); off-state output terminal voltage 60V (min); and isolation voltage 1500 Vrms (min).
