BT136 TRIAC 600V 4A TO-220 | AC Power Control Switch for Dimmer, Motor & Heater | Sri Lanka

The BT136 TRIAC is a reliable and widely used bidirectional switching component designed for efficient AC power control applications. Built in a durable TO-220 package, this TRIAC supports up to 600V blocking voltage and 4A RMS current, making it ideal for medium-power switching circuits. It is commonly used in light dimmers, fan speed controllers, heater controls, and motor speed regulation systems.

Technically, the BT136 operates as a three-terminal device (MT1, MT2, Gate) that can conduct current in both directions when triggered, allowing smooth phase control in AC circuits. It features low gate trigger current, ensuring compatibility with microcontroller-based circuits and optocouplers like MOC3021 or MOC3063. Its high commutation capability and stable switching performance make it a preferred choice for both DIY electronics and industrial repair work.

This TRIAC is perfect for applications such as AC lamp dimming, fan regulators, temperature control systems, and home automation projects. Whether you are repairing appliances or building new circuits, the BT136 offers consistent and dependable performance.
