BTA24, BTB24, BTA25

BTA26, BTB26, T25

25 A standard and Snubberless™ triacs

Features

■ High current triac

■ Low thermal resistance with clip bonding

■ High commutation (4 quadrant) or very high

commutation (3 quadrant) capability

■ BTA series UL1557 certified (File ref: 81734)

■ Packages are RoHS (2002/95/EC) compliant

Applications

Applications include the ON/OFF function in

applications such as static relays, heating

regulation, induction motor starting circuits, etc.,

or for phase control operation in light dimmers,

motor speed controllers, and silmilar.

The snubberless versions (BTA/BTB...W and T25

series) are especially recommended for use on

inductive loads, due to 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 BTA24, BTB24, BTA25, BTA26,

BTB26 and T25 triac series is suitable for general

purpose mains power AC switching.
