BT136 600V – 4A Triac

The BT136 600V – 4A Triac is a three-terminal semiconductor switching device designed for controlling AC power in electronic and electrical circuits. It is capable of handling a maximum voltage of 600V and a current rating of 4A, making it suitable for medium-power AC switching and control applications. The Triac acts like an electronic switch that can control the flow of alternating current (AC) by turning ON and OFF through a small gate trigger signal.

The BT136 Triac has three terminals: MT1 (Main Terminal 1), MT2 (Main Terminal 2), and Gate. When a small triggering current is applied to the gate terminal, the device starts conducting current between MT1 and MT2 and continues conducting until the AC current falls below the holding current level. This feature makes it ideal for controlling AC loads such as lamps, fans, heaters, and motors.

This Triac is widely used in light dimmer circuits, fan speed controllers, temperature control systems, motor speed regulation, and industrial automation applications. It is commonly used with microcontrollers like Arduino through suitable driver circuits to control AC appliances. The BT136 provides efficient switching, high reliability, and good thermal performance when used with proper heat dissipation.

The BT136 600V – 4A Triac is available in a compact TO-220 package, allowing easy installation on PCBs and heat sinks for improved performance. It is an excellent choice for students, hobbyists, technicians, and engineers working on power control circuits, automation projects, and electronic switching applications.

The BT136 600V 4A TRIAC is a reliable and widely used semiconductor device designed for controlling AC power in a variety of electronic and electrical applications. Rated for a maximum repetitive peak off-state voltage of 600V and a current handling capacity of up to 4A, this TRIAC is suitable for medium-power AC switching and phase control tasks. It is commonly used in applications such as light dimmers, fan speed controllers, heater controls, motor speed regulators, and solid-state switching circuits.

The BT136 TRIAC offers stable triggering characteristics and efficient bidirectional current conduction, allowing it to control AC loads with precision and reliability.
