1/6 ? bta40 and bta/btb41 series standard 40a triac s september 2003 - ed: 5 main features: description available in high power packages, the bta/ btb40-41 series is suitable for general purpose ac power switching. they can be used as an on/ off function in applications such as static relays, heating regulation, water heaters, induction motor starting circuits, welding equipment... or for phase control operation in high power motor speed con- trollers, soft start circuits... 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 2500 v 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 absolute maximum ratings symbol parameter value unit i t(rms) rms on-state current (full sine wave) rd91 tc = 80c 40 a top3 top3 ins. tc = 95c i tsm non repetitive surge peak on-state current (full cycle, tj initial = 25c) f = 60 hz t = 16.7 ms 420 a f = 50 hz t = 20 ms 400 i 2 ti 2 t value for fusing tp = 10 ms 880 a 2 s di/dt critical rate of rise of on-state current i g = 2 x i gt , tr 100 ns f = 120 hz tj = 125c 50 a/s v dsm /v rsm non repetitive surge peak off-state voltage tp = 10 ms tj = 25c v drm /v rrm + 100 v i gm peak gate current tp = 20 s tj = 125c 8 a p g(av) average gate power dissipation tj = 125c 1 w t stg t j storage junction temperature range operating junction temperature range - 40 to + 150 - 40 to + 125 c g a2 a1 a1 a2 g a2 a2 a1 g rd91 (bta40) a1 a2 g top3 (btb41) top3 insulated (bta41)
