TXDV1212RG

TXDV1212RG Description

The TXDV1212RG from STMicroelectronics is a high-performance standard TRIAC designed for robust switching applications. Housed in a TO-220AB package, it features a 1.2 kV off-state voltage and a 12 A RMS on-state current, making it suitable for medium-to-high-power AC load control. With a gate trigger current (Igt) of 100 mA max and a gate trigger voltage (Vgt) of 1.5 V max, it ensures reliable triggering under varying conditions. The device is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards. Its non-repetitive surge current (Itsm) of 120A (50Hz) / 125A (60Hz) highlights its ability to handle transient overloads, while the 100 mA holding current (Ih) ensures stable operation in latching applications.
