Description
Specifically designed to operate at 800 V and 150 °C, the T1235H-8I Triac housed in TO-220AB insulated provides an enhanced thermal management: this 12 A Triac is the right choice for a compact drive of AC loads and enables the heatsink size reduction. Based on the ST high temperature Snubberless technology, it offers higher specified turn off commutation and noise immunity levels up to the Tj max. Snubberless is a trademark of STMicroelectronics. The T1235H-8I safely optimizes the control of the motors and heaters loads for the most constraining environments of home appliances and industrial control. By using an internal ceramic pad, it provides a recognized voltage insulation, rated at 2500 VRMS.
