1. 10/1000µS waveform non-repetitive current pulse, and derated above Ta=25oC
2. Tl=75oC, lead length 9.5mm, Mounted on copper pad area of (40×40mm)
3. Measured on 8.3ms single half sine-wave or equivalent square wave,duty cycle=4 pulses per minute maximum.
4. VF=3.5V max. for devices of V(BR) 200V, and VF=5.0V max. for devices of V(BR) >200V
DEVICES FOR BIDIRECTIONAL APPLICATIONS
1. Suffix 'A' dnotes 5% tolerance device,no suffix 'A' dnotes 10% tolerance device.
2. For bidirectional use 'C' or 'CA' suffix for types P4KE7.5 thru types P4KE440A
(e.g. P4KE7.5C,P4KE440CA), for unidirectional don't use 'C' suffix after types.
3. For bidirectional devices having VWM of 10 volts and less, the ID limit is doubled.
4. Electrical characteristics apply in both directions.
