T1235-600G

T1235-600G Description

The T1235-600G from STMicroelectronics is a high-performance Snubberless™ TRIAC designed for robust switching applications. This 600V, 12A alternistor is housed in a D2PAK surface-mount package, offering superior thermal and electrical performance. As part of the Snubberless™ series, it eliminates the need for external snubber circuits, reducing component count and system cost. With a gate trigger current (Igt) of 35mA max and a gate trigger voltage (Vgt) of 1.3V max, it ensures reliable triggering under varying conditions. Its non-repetitive surge current (Itsm) of 120A (50Hz) and 126A (60Hz) highlights its ability to handle high inrush currents, making it ideal for demanding environments.
