table 1: main features description the bta20 bw/cw triac family are high perform- ance glass passivated chips technology. the snubberless concept offer suppression of rc network and it is suitable for application such as phase control and static switching on inductive or resistive load. 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) 20 a v drm /v rrm 600 and 700 v i gt (q 1 ) (max) 35 and 50 ma 20a triac s table 2: order codes part numbers marking BTA20-600Bwrg BTA20-600Bw bta20-600cwrg bta20-600cw bta20-700bwrg bta20-700bw bta20-700cwrg bta20-700cw a2 a1 g to-220ab insulated table 3: absolute maximum ratings symbol parameter value unit i t(rms) rms on-state current (full sine wave) t c = 70c 20 a i tsm non repetitive surge peak on-state current (full cycle, t j initial = 25c) f = 50 hz t = 10 ms 210 a f = 60 hz t = 8.3 ms 200 i 2 ti 2 t value for fusing t p = 10 ms 200 a 2 s di/dt critical rate of rise of on-state current i g = 500 ma di g /dt = 1 a/s repetitive f = 50 hz t j = 125c 20 a/s non repetitive 100 v dsm /v rsm non repetitive peak off-state voltage t p = 10 ms t j = 25c v dsm /v rsm + 100 v i gm peak gate current t p = 20 s t j = 125c 4a v gm peak positive gate voltage t p = 20 s 16 v p g(av) average gate power dissipation t j = 125c 1w t stg t j storage junction temperature range operating junction temperature range - 40 to + 150 - 40 to + 125 c bta20 series 2014-6-10 1 www.kersemi.com
