A TRIAC, short for “triode for alternating current,” is a type of electronic component that acts as a bidirectional switch for controlling AC (alternating current) power. It’s often used for controlling the intensity of lamps, the speed of AC motors, and other applications where precise control of AC power is needed.

Description
This is 25A, Triacs. Available either in through-hole or surface-mount packages, the BTA24, BTB24, BTA25, BTA26, BTB26 and T25 triac series is suitable for general purpose mains power AC switching.
Features
1. High current triac
2. Low thermal resistance with clip bonding
3. High commutation (4 quadrant) or very high commutation (3 quadrant) capability
4. BTA series UL1557 certified (File ref: 81734)
5. Packages are RoHS (2002/95/EC) compliant
Applications:
Applications include the ON/OFF function in applications such as static relays, heating regulation, induction motor starting circuits, etc., or for phase control operation in light dimmers,
motor speed controllers, and silmilar.
The snubberless versions (BTA/BTB…W and T25 series) are especially recommended for use on
inductive loads, due to their high commutation performances. The BTA series provides an
insulated tab (rated at 2500 VRMS).
