2N3894

The 2N3894 is a powerex silicon controlled rectifiers(SCR).It is designed for phase control aoolications.These are all-diffused,compression bonded encapsulated(CBE) decives employing the field-proven amplifying(di/namic)gate.

Features of the 2N3894 are:(1)low on state voltage;(2)high di/dt;(3)high dv/dt;(4)hermetic packaging;(5)excellent surge and I²t ratings.

The absolute maximum ratings of the 2N3894 can be summarized as:(1)RMS on state current,I_T(RMS):275A;(2)average on state current,I_T(av):175A;(3)peak one cycle surge(non-repetitive)on state current(60Hz),I_TSM:4500A;(4)peak one cycle surge(non-repetitive)on state current(50Hz),I_TSM:4100A;(5)critial rate of rise of on state current(repetitive),di/dt:800A/s;(6)critial rate of rise of on state current(non-repetitive),di/dt:150A/s;(7)I²t(for fusing),8.3 milliseconds,I²t:84000 A²sec;(8)peak gate power dissipation,P_GM:15W;(9)average gate power dissipation,P_G(av):3W;(10)storgae temperature,T_STG:-40 to +150;(11)operating temperature,T_J:-40 to +125;(12)mounting torque:300in.-lb.;(13)mounting torque:340kg-cm.
