BTB24 BSTANDARD TRIACS HIGH SURGE CURRENT CAPABILITY. COMMUTATION : (dV/dt)c > 10V/μs
DESCRIPTION
ABSOLUTE RATINGS (limiting values)
FEATURESThe BTB24 B triac family are high performance
glass passivated PNPN devices.
These parts are suitables for general purpose ap-
plications where high surge current capability is re-
quired. Application such as phase control and
static switching on inductive or resistive load.
