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

TLP4590A 1-Form-B Photorelay
TLP4590A 1-Form-B Photorelay from Toshiba Electronics

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. 


Features of TLP4590A 1-Form-B Photorelay

  • Normally closed (1-Form-B) 
  • OFF-state output terminal voltage: 60 V (min) 
  • Trigger LED current: 2 mA (max) 
  • ON-state current: 1.2 A (max) (T a = 25℃) 
  • ON-state resistance: 0.6 Ω (max) 
  • Isolation voltage: 5000 Vrms (min)


Note: More technical information can be found in the TLP4590A Datasheet linked at the bottom of this page and in the product page of TLP4590A 1-Form-B Photorelay.
