DESCRIPTION
The BTA41 A/B / BTB41 B triac family are high Ai
performance glass passivated PNPN devices. A2 &
These parts are suitables for general purpose ap-
plications where high surge current capability is re- TOP 3
quired. Application such as phase control and (Plastic)
static switching on inductive or resistive load.
