BT139-800E.

The BT139-800E is one of the BT139-xxe series.BT139-800Eis a triacs sensitive gate.Glass passivated,sensitive gate triacs in a full pack, plastic envelope,intended for use in general purpose bidirectional switching and phase control applications,where high sensitivity is required in all four quadrants.

The absolute maximum ratings of the BT139-800E can be summarized as:(1)repetitive peak off-state voltages,V_DRM:800V;(2)RMS on-state current(full sine wave;T_hs99),I_T(RMS):8A;(3)non-repetitive peak on-state current:full sine wave,I_TSM;T_j=25 proior to surge;(4)I²t for fusing,I²t:t=20ms...140At=16.7ms...150At=10ms...98A²S;(5)repetitive rate of rise of on-state current after triggering,dI_T/dt(I_TM=12A,I_G=0.2A,dI_G/dt=0.2A/S):T2+G+...50A/ST2+G-...50A/ST2-G-...50A/ST2-G+...10A/S;(6)peak gate current,I_GM:2A;(7)peak gate voltage,V_GM:5V;(8)peak gate power:5W;(9)average gate power(over any 20ms period),P_G(AV):0.5W;(10)storage temperature,T_stg:-40 to 150;(11)operating junction temperature,T_j:125.1 Although not recommended, off-state voltages up to 800V may be applied without damage,but the triac may switch to the on-state.The rate of rise of current should not exceed 15 A/s.
