Overview
The BT136-600E is a planar passivated sensitive gate four-quadrant triac manufactured by NXP USA Inc. This component is designed for general purpose bidirectional switching and phase control applications. It is particularly suited for use in circuits that require direct triggering from low power drivers and logic integrated circuits due to its low gate threshold voltage. The BT136-600E is packaged in a TO-220AB (SOT78) plastic single-ended package, which is heatsink mounted and includes a mounting hole for secure installation.
