T4700B

The RCA T4700 series are gate-controlled full-wave ac silicon switches.They are designed to switch from an off-state to a conducting state for either polarity of applied voltage with positive or negative gate triggering.The T4700B belongs to T4700 series.

Features of the T4700B are:(1)800V,125DEg. C TJ operating;(2)high dv/dt and di/dt capability;(3)low switching losses;(4)high pulse current capability;(5)low forward and reverse leakage;(6)sipos oxide glass multilayer passivation system;(7)advanced unisurface construction;(8)precise lon implanted diffusion source.

The absolute maximum ratings of the T4700B can be summarized as:(1):the parameter is repetitive peak off-state voltage,the symbol is VDROM,the rating is 200,the unit is V;(2):the parameter is RMS on-state current,the symbol is IT(RMS),the rating is 15,the unit is A;(3):the parameter is peak surge(non-repetitive) on-state current,the symbol is ITSM,the rating is 100,85,the unit is A;(4):the parameter is peak gate-trigger current,the symbol is IGTM,the rating is 4,the unit is A;(5):the parameter is fusing current,the symbol is I2t,the rating is 50,the unit is A2s;(6):the parameter is gate power dissipation peak,the symbol is PGM,the rating is 16,the unit is W;(7):the parameter is gate power dissipation average,the symbol is PG(AV),the rating is 0.45,the unit is W;(8):the parameter is temperature range storage,the symbol is Tstg,the rating is -40 to 150,the unit is ;(9):the parameter is temperature range operating,the symbol is Tc,the rating is -40 to 125,the unit is ;(10):the parameter is pin temperature (during soldering),the symbol is Tp,the rating is 225,,the unit is .
