Toshiba TLP4590A & TLP4590AF Photorelays

Toshiba TLP4590A and TLP4590AF Photorelays integrate a photo MOSFET optically coupled to an infrared light-emitting diode. These devices are designed to replace mechanical relays in applications to save space and increase reliability. The TLP4590A and TLP4590AF Photorelays are normally closed (1-Form-B) and feature a low 0.6Ω ON-state resistance. These devices also feature an isolation voltage of 5000Vrms, making them ideal for applications that require reinforced insulation.

The Toshiba TLP4590A and TLP4590AF Photorelays are offered in compact 6-pin DIP packages with through-hole and surface mount lead options.
