BTA/BTB12 and T12 Series

SNUBBERLESS™, LOGIC LEVEL & STANDARD

September 2002 - Ed: 6A

MAIN FEATURES:

DESCRIPTION

Available either in through-hole or surface-mount

packages, the BTA/BTB12 and T12 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 T12

series) are specially recommended for use on

inductive loads, thanks to their high commutation

performances. Logic level versions are designed

to interface directly with low power drivers such as

microcontrollers. By using an internal ceramic

pad, the BTA series provides voltage insulated tab

(rated

at

2500V

RMS)

complying

with

UL

standards (File ref.: E81734)
