MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS

Rating 25C ambient temperature uniess otherwies specified.

Single phase half wave, 60Hz, resistive or inductive load.

For capacitive load, derate current by 20%.

NOTES:

1.Non-repetitive current pulse per Fig. 3 and derated above TA=25C per Fig. 2.

2.Mounted on Copper Pad area of 5.0mm2(.013mm Thick) to each terminal.

3.8.3ms single half sine-wave, duty cycle = 4 pulses per minute maximum.

DEVICES FOR BIPOLAR APPLICATIONS

1.For Bidirectional use C or CA Suffix for types SMAJ5.0 thru SMAJ170.

2.Electrical characteristics apply in both directions.
