TPDV1225 general description 25a triacs available either in through-hole or surface-mount packages, the TPDV1225 triac series is suitable for general purpose ac switching. they can be used as an on/off function in applications such as static relays, heating regulation, induction motor starting circuits... or for phase control operation in light dimmers, motor speed controllers, ... the snubberless versions (tpdv series) are specially recommended for use on inductive loads, thanks to their high commutation performances. by using an internal ceramic pad, the bta series provides voltage insulated tab (rated at 2500v rms) complying with ul standards. product specification absolute maximum ratings electrical characteristics ( ta = 25 c) o ( ta = 25 c) o a1 a2 g parameter symbol value unit repetitive peak off-state voltages v drm 1200 v peak off-state reverse voltages v rrm 1200 v rms on-state current i t 25.0 a non-repetitive peak on-state current i tsm 260 a max. operating junction temperature t j 110 o c storage temperature t stg -45~150 o c parameter symbol test conditions min. max unit repetitive peak off-state voltages v drm i d =0.1ma 1200 v repetitive peak off-state current i drm v drm =1100v 10 ua on-state voltage v tm i t =35a 1.55 v holding current i h i t =0.5a,i gt =25ma 150 ma gate trigger current t2+g+ i gt v ak =12v r l =30 150 ma t2+g- 150 t2-g- 150 gate trigger voltage t2+g+ v gt v d =12v r l =30 1.5 v t2+g- 1.5 t2-g- 1.5 to-3p tiger electronic co.,ltd
