FEATURES

HIGH SURGE CURRENT CAPABILITY

.

COMMUTATION : (dV/dt)c > 10V/µs

.

BTB24 B

STANDARD TRIACS

DESCRIPTION

The BTB24 B triac family are high performance
glass passivated PNPN devices.
These parts are suitables for general purpose ap­plications where high surge current capability is re­quired. Application such as phase control and
static switching on inductive or resistive load.
