Features
• High current Triac • Low thermal resistance with clip bonding • Standard commutation (4 quadrants) or snubberless (3 quadrants), both with
high turn-off commutation • BTA26 UL1557 recognized components (file ref: 81734) • RoHS (2002/95/EC) compliant packages
Application
• 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 TOP3 insulated and non-insulated package, BTA26 and BTB26 are suitable for general purpose AC switching. BTA26 and BTB26 provide an insulated tab (rated at 2500 VRMS). These components are UL recognized and meet UL 1557 (file ref. 81734).
