table 1: main features description available in high power packages, the bta/ btb40-41 series is suitable for general purpose ac switching. they can be used as an on/off function in applications such as static relays, heat- ing regulation, induction motor starting circuits... or for phase control operation in light dimmers, motor speed controllers, ... thanks to their clip assembly technique, they provide a superior performance in surge current handling capabilities. by using an internal ceramic pad, the bta series provides voltage insulated tab (rated at 2500v rms ) complying with ul standards (file ref.: e81734). symbol value unit i t(rms) 40 a v drm /v rrm 600 and 800 v i gt (q 1 ) 50 ma 40a triac s table 2: order codes part number marking bta40-xxxb see table 8 on page 6 bta41-xxxbrg btb41-xxxbrg top3 insulated (bta41) top3 (btb41) a2 a1 g rd91 (bta40) bta40, bta41 and btb41 series 2014-6-16 www.kersemi.com 1
