  • High operating temperature rating: Topr(max)=110°C
  • Normally opened (1-Form-A)
  • OFF-state output terminal voltage: 100 V (min)
  • Trigger LED current: 5.0 mA (max)

Toshiba's 100V TLP3823 with 3A drive current and the 200V TLP3825 with 1.5A drive current – two mid-voltage, high-current photorelays.

The new products will extend the range of high-current photorelays to replace mechanical relays, alongside Toshiba’s existing 60V, 5A TLP3547.

Toshiba is supporting and promoting the accelerated replacement of mechanical relays by applying its latest trench MOSFET structure, 8th generation UMOS, to realize output currents exceeding 1A.

Photorelays have no physical contacts that incur wear and tear, thus contributing to significantly increased reliability.
