Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched “TLP4590A,” a 1-Form-B (normally closed) photorelay in a DIP6 package featuring an industry-leading 1.2A increased ON-state current rating and a 60V OFF-state output terminal voltage rating. Volume shipments start today.
The ON-state current rating of 1.2A is the highest in the industry, 140% higher than Toshiba’s current product, TLP4176A. The maximum operating temperature rating of 110℃ 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. TLP4590A also features an isolation voltage (min.) of 5,000Vrms, allowing it to be used in equipment that requires high insulation performance.
