Description
Specifically designed to operate at 800 V and 150 °C, the T1235H-8G Triac housed in D2PAK 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. D2PAK package is ideal for compact SMD designs on surface mount boards or insulated metal substrate boards. Based on the ST high temperature Snubberless technology, it offers higher specified turn off commutation and noise immunity levels up to the Tj max. The T1235H-8G 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.
