12A Bidirectional Triode Thyristor BTA12-600BW With Medium Current
Features
■ Medium current triac
■ Low thermal resistance with clip bonding
■ Low thermal resistance insulation ceramic for insulated BTA
■ High commutation (4Q) or very high commutation (3Q) capability
■ BTA series UL1557 certified (File ref: 81734)
■ 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 performances.
The BTA series provides an insulated tab (rated at 2500 V RMS).
Description
Available either in through-hole or surface-mount packages, the BTA12, BTB12 and T12xx triac series is suitable for general purpose mains power AC switching.
