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 1.5KE6.8 thru types 1.5KE440A
(e.g. 1.5KE7.5C,1.5KE440CA), 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.
