Note:
• 1.5KE250 ~ 1.5KE540A and 1.5KE250C ~ 1.5KE440CA for
commercial grade only
Polarity: For uni-directional types the color band
denotes cathode end, no marking on bi-directional
types
DEVICES FOR BI-DIRECTION APPLICATIONS
For bi-directional types, use C or CA suffix
(e.g. 1.5KE440CA).
Electrical characteristics apply in both directions.
