BT137-600E Triac Logic Level

The BT137-600E Triac Logic Level is a sensitive-gate triac in a TO-220 package, rated 8A RMS and 600V. Its low gate-trigger current means it can be fired through an optotriac such as the MOC3021 or MOC3041 from a microcontroller, which makes it a popular choice for AC dimmers and Arduino AC control.

BT137-600E Triac Logic Level – Key Features

• Part number: BT137-600E
• On-state current: 8A RMS
• Repetitive peak off-state voltage: 600V
• Sensitive gate (E version)
• Package: TO-220AB

Applications

Makers, students and technicians use it in many kinds of projects, for example:

• AC light dimmers
• Universal motor and fan speed control
• Heater and AC load switching
• Solid-state relay circuits
• Repair of appliances and controllers

Usage Tips

The metal tab is connected to MT2, so insulate it when mounting several triacs on one heat sink. Use a heat sink above about 2A, and add an RC snubber when switching inductive loads such as motors.
