BTA24, BTB24, BTA25, BTA26

and T25 series

Snuberrless™ and Standard

25 A Triacs

Main features

Description

Available either in through-hole or surface-mount

packages, the BTA24, BTB24, BTA25, BTA26

and T25 triac series is suitable for general

purpose AC switching. They can be used as an

ON/OFF function in applications such as static

relays, heating regulation, induction motor starting

circuits... or for phase control operation in light

dimmers, motor speed controllers, ...

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

series) are specially recommended for use on

inductive loads, thanks to their high commutation

performances. By using an internal ceramic pad,

the BTA series provides voltage insulated tab

(rated at 2500V

RMS

) complying with UL standards

(File ref.: E81734).
