Product Introduction

Overview

The T1235T-8T Triac, produced by STMicroelectronics, is a 12 A, 800 V snubberless Triac designed for general purpose AC switching applications. It is housed in a TO-220AB through-hole package, making it suitable for on/off or phase angle control functions in various AC load control scenarios. This component is part of STMicroelectronics' Snubberless high temperature technology, offering enhanced thermal management and robust dynamic turn-off commutation.
