NOTES:
1. Unless Otherwise Specified, All Electrical C haracteristics @25ºC.
2. Resistive Load, 60Hz, Sine Wave, TC=25^OC.
3. TC=55^OC, 8.3ms Pulse, Allow Junction to Reach Equilibrium Between Pulses.
4. TC=55^OC, 8.3ms Pulse, Superimposed on Rated Current at Rated Voltage.
5. Recovery Conditions: IF = 0.5 Amp, IR = 1.0 Amp rec. to .25 Amp,
tested on each individual diode before assembly.
6. IO (MAX), 60Hz, Square Wave, TC = 55^OC.
7. IF = 1 Adc, TC = 25^OC, 300 μs Pulse.
8. Rated VR, 60Hz, Square Wave, TC = 100^OC.
9. Rated VR, TC = 25^OC.
10. VR = 100V, TC = 25^OC.
NOTE: All specifications are subject to change without notification.
SCD's for these devices should be reviewed by SSDI prior to release.
