12a triac s main features: description available either in through-hole or surface-mount packages, the bta/btb12 and t12 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 (bta/btb...w and t12 series) are specially recommended for use on inductive loads, thanks to their high commutation performances. logic level versions are designed to interface directly with low power drivers such as microcontrollers. 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) 12 a v drm /v rrm 600 and 800 v i gt (q 1 ) 5 to 50 ma absolute maximum ratings symbol parameter value unit i t(rms) rms on-state current (full sine wave) d 2 pak/to-220ab tc = 105c 12 a to-220ab ins. tc = 90c i tsm non repetitive surge peak on-state current (full cycle, tj initial = 25c) f = 50 hz t = 20 ms 120 a f = 60 hz t = 16.7 ms 126 i 2 ti 2 t value for fusing tp = 10 ms 78 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 4 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 d 2 pa k (t12-g) to-220ab insulated (bta12) to-220ab (btb12) bta/btb12 and t12 series 2014-6-9 1 www.kersemi.com
