Description
The BT138-600E is a logic-level TRIAC designed for general-purpose switching and phase control of AC loads. Rated for 600V and up to 12A RMS on-state current, it is ideal for dimmer circuits, AC motor control, heater regulation, and solid-state relays.
What sets this variant apart is its low gate trigger current, which allows direct interfacing with microcontrollers (such as Arduino, ESP32, or STM32) without the need for a driver transistor—making it perfect for logic-level control applications.
Packaged in a TO-220 case, the BT138-600E offers good thermal performance and ease of mounting in PCB and heat sink configurations.
