Description

Available in power packages, the BTA40, BTA41, and BTB41 are suitable for general

purpose AC switching.

When used with the properly dimensioned heatsink, the BTA40, BTA41 and BTB41

can enable AC switching systems up to 9 kW. Refer to STMicroelectronics

application note AN533 for thermal management of Triacs.

The BTA40, and BTA41 provides an insulated tab (rated at 2500 V rms). They are

recognized by UL. Representative samples of these components have been

evaluated by UL and meet applicable UL requirements for the UL 1557 standard (file

Ref. 81734).
