Product overview
Description
Specifically designed to operate at 800 V and 150 °C, the T835H-8T Triac housed in TO-220AB provides an enhanced thermal management: this 8 A Triac is the right choice for a compact drive of AC loads and enables the heatsink size reduction.
Based on the ST Snubberless high temperature technology, it offers higher specified turn off commutation and noise immunity levels up to the Tj max.
The T835H-8T safely optimizes the control of the hardest universal motors, heaters and inductive loads for industrial control and home appliances.
Snubberless is a trademark of STMicroelectronics.
