Available either in through-hole and surface-mount packages, these devices are suitable for general purpose AC switching. They can be used as an ON/OFF function in applications such as static relays, heating regulation, induction motor starting circuits or for phase control operation in light dimmers and motor speed controllers, etc. The Snubberless versions (BTA, BTB08_xxxxW and T8 series) are specially recommended for use on inductive loads, thanks to their high commutation performance. Logic level versions are designed to interface directly with low power drivers such as Microcontrollers. By using an internal ceramic pad, the BTA series provide voltage insulated tab (rated at 2500 VRMS) in compliance with UL standards (file ref.: E81734).

Specifically designed to operate at 800 V and 150 °C, the T835H-8G Triac housed in D2PAK 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. 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 Tjmax. The T835H-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.

Available in through-hole, the T8T series of Triacs can be used as on/off or phase angle control function in general purpose ac switching where high commutation capability is required. This series can be designed in many value sensitive appliances thanks to the parameters guidance provided in the following pages. Provides insulation rated at 2500 V rms (TO-220AB insulated package).

Available in SMD, the T835T-8G Triac can be used for the on/off or phase angle control function in general purpose AC switching where high commutation capability is required. The T835T-8G can be used without a snubber RC circuit when the limits defined are respected. D2PAK package is UL-94,V0 flammability resin compliance. Package environmentally friendly Ecopack®2 graded (RoHS and Halogen Free compliance). Snubberless™ is a trademark of STMicroelectronics.
