Toshiba TLP4590A 1-Form-B photorelay

Toshiba Electronic Devices & Storage has launched the TLP4590A, a 1-Form-B (normally closed) photorelay in a DIP6 package featuring a 1.2 A increased ON-state current rating and a 60 V OFF-state output terminal voltage rating. The ON-state current rating of 1.2 A is 140% higher than Toshiba’s TLP4176A.

The maximum operating temperature rating of 110°C facilitates easy achievement of designs with the temperature margins required for application in heating, ventilation and air conditioning (HVAC), security systems and building automation system equipment, where many 1-Form-B relays are used. Other suitable applications include industrial equipment (programmable logic controllers, I/O interface and various sensor control, etc) and replacement of mechanical relays.

The product features an isolation voltage (min) of 5000 V_rms, allowing it to be used in equipment that requires high insulation performance.
