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 V
WM
of 10 volts and less, the I
D
limit is doubled.
4. Electrical characteristics apply in both directions.
