This document describes the features and characteristics of the BTA24, BTB24, BTA25, BTA26, BTB26, and T25 series triacs, including high current, low thermal resistance, high commutation capability, and applications in static relays, heating regulation, induction motor starting circuits, light dimmers, motor speed controllers, etc.
This document is a datasheet for the STMicroelectronics BTA24, BTB24, BTA25, BTA26, BTB26, and T25 triac series. These devices are standard and snubberless triacs suitable for general-purpose mains power AC switching and inductive load applications. The series includes insulated and non-insulated packages with ratings up to 25 A RMS and 800 V.
Applications include ON/OFF functions in static relays, heating regulation, induction motor starting circuits, and phase control in light dimmers.
The snubberless versions (BTA/BTB...W and T25 series) are especially recommended for use on inductive loads.
Yes, the packages are RoHS (2002/95/EC) compliant.
