Product details

Protection parameters — what the ratings mean for your rail

The 1.5KE30AG: Unidirectional (single-channel) Zener construction means it clamps only one polarity — if the application sees bidirectional transients, a pair back-to-back or a bidirectional part is needed.

DO-201AD axial — board-fit and replacement note

Through-hole DO-201AD axial package (supplier device package also listed as Axial) — the body diameter and lead spacing match the standard DO-201 footprint used across the 1.5KE family.

Frequently asked questions

What compliance documentation does Littelfuse provide for the 1.5KE30AG?

The evidence does not list specific compliance certifications (RoHS, REACH, UL, IEC) for this part. Littelfuse typically provides RoHS and REACH declarations for active products; for an obsolete part, documentation availability should be confirmed at RFQ.
