ELECTRICAL CHARACTERISTICS AND RATINGS

Notes:

All ratings are specified for Tj=25 ^oC unless

otherwise stated.

(1) All voltage ratings are specified for an applied

50Hz/60zHz sinusoidal waveform over the

temperature range -40 to +125^oC.

(2) 10 msec. max. pulse width

(3) Maximum value for Tj = 125^oC.

(4) See parameter definition below :

Reverse Blocking

V_RRM = Repetitive peak reverse voltage

V_RSM = Non repetitive peak reverse voltage (2)
