The ON-state current rating of 1.2A is the highest in the industry[1], 140% higher than Toshiba’s current product, TLP4176A[2]. 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.

[1] For photorelays (1-Form-B) where OFF-state output terminal voltage rating is 60V, according to a survey by Toshiba (as of May 11, 2021).
