T12

      TheT12 triac series is available either in through-hole or surface-mount  packages, and it 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 R_MS) complying with UL standards. Its main features are : I_T(RMS) is 12 A . VDRM and VRRM are 600 V and 800 V . I_GT(Q1) is 5 mA to 50 mA. There are some absolute maximum ratings about it . (I_T(RMS) ) RMS on-state current (full sine wave)(D²PAK/TO-220AB Tc = 105°C) is 12 A and is 12 A (TO-220AB Ins. Tc = 90°C).(I_TSM) Non repetitive surge peak on-state current (full cycle, Tj initial = 25°C)is 120 A(F = 50 Hz t = 20 ms) and 126 A (F = 60 Hz t = 16.7 ms). (I²t) I²t Value for fusing( tp = 10 ms) is 78 A²s.(dI/dt) Critical rate of rise of on-state current(IG = 2 x IGT , tr £ 100 ns F = 120 Hz Tj = 125°C) is 50 A/s.(VDSM/VRSM)Non repetitive surge peak off-state voltage(tp = 10 ms Tj = 25°C) is V_DRM/V_RRM+ 100 V.(I_GM ) Peak gate current(tp = 20 s Tj = 125°C) is 4 A.(P_G(AV) ) Average gate power dissipation(Tj = 125°C) is  1 W.(Tstg) Storage junction temperature range is - 40°C to + 150°C.(Tj) Operating junction temperature range is - 40°C to + 125 °C.
