FEATURES
HIGH SURGE CURRENT CAPABILITY
COMMUTATION : (dV/dt)c > 10V/µs
BTA Family :
INSULATING VOLTAGE = 2500V
(RMS)
(UL RECOGNIZED : E81734)
DESCRIPTION
The BTA41 A/B / BTB41 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.
