Features
• High current Triac
• Low thermal resistance
• BTA40 and BTA41 UL1557 recognized components (file ref: 81734)
• RoHS (2002/95/EC) compliant packages
• UL-94, V0 flammability package resin compliance
Applications
• On/off function in static relays, heating regulation, induction motor starting
circuits
• Phase control operations in light dimmers and motor speed controllers
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 ST Application Note AN533
for thermal management of Triacs.
The BTA40, BTA41 and BTB41 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 UL 1557 standard (File
Ref. 81734).
