TLP4590A 1-Form-B Photorelay with 60V OFF-state Output Terminal Voltage Rating for Space-Constraint Applications

17 May 2021 - 0 Comments

Toshiba Electronics Devices and Storage Corporation has introduced the TLP4590A, a 1-Form-B (normally closed) photo relay with a 60V OFF-state output terminal voltage rating. The new device offers high ON-state current rating of 1.2A in a DIP6 package.

With a maximum operating temperature of 110℃, the TLP4590A allows users to achieve 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. The TLP4590A also features an isolation voltage of 50,000 Vrms, hence they can be used in equipment requiring high insulation performance.
