Triac, SOT-428, 600V, 8A, Very Sensitive Gate, 1.814g

The BT137S-600D,118 from WEEN SEMICONDUCTORS is a 3-pin planar passivated triac, engineered for general purpose bidirectional switching and phase control applications. This very sensitive gate 4-quadrant triac is designed to interface directly with microcontrollers, logic integrated circuits, and other low power gate trigger circuits, offering significant flexibility and simplifying control system design.

A key feature of this component is its direct triggering capability from low power drivers and logic ICs, eliminating the need for additional amplification stages and reducing overall circuit complexity. It boasts a high blocking voltage capability of 600V, providing robust protection and reliability in demanding electrical environments. The low holding current makes it particularly suitable for low current loads and contributes to the lowest possible electromagnetic interference (EMI) at commutation.
