STMicroelectronics Standard and Snubberless™ Triacs
STMicroelectronics Standard and Snubberless™ Triacs are available in through-hole or surface-mount packages and are suitable for general purpose mains power AC switching. These triacs can be used as an ON/OFF function for applications like static relays, heating regulation, or induction motor starting circuits. The Snubberless versions are especially recommended for use on inductive loads, due to high commutation performance.
Features
- Medium current triac
- Low thermal resistance with clip bonding
- Low thermal resistance ceramic for insulated BTA
- BTA series UL1557 certified (file ref: 81734)
- High commutation (4Q) or very high commutation (3Q, Snubberless™) capability
- Packages are RoHS (2002/95/EC) compliant
Applications
- ON/OFF or phase angle function in applications such as static relays, light dimmers, and appliance motors speed controllers.
- The Snubberless™ versions (BTA/BTB...W and T12 series) are especially recommended for use on inductive loads, because of their high commutation performance.
- The BTA series provides an insulated tab (rated at 2500 VRMS).
