FEATURES
HIGH SURGE CURRENT CAPABILITY
COMMUTATION : (dV/dt)c > 10V/µs
DESCRIPTION
A1
A2
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.
