18V 5W 1N5355B Zener Diode (5-Piece Pack)

Completing the run of common zener voltage points in this series, the 18V-rated 1N5355B extends overvoltage protection coverage to higher-voltage supply rails and reference circuits that the lower 6.2V, 10V, 12V, and 15V parts in this range don't reach. Keeping a spread of these specific voltage points on hand means a builder working on a protection circuit or voltage-sensing design can grab the exact clamping voltage a schematic calls for without needing to special-order a single part for every different project.
