Product details

The 1.5KE24A-T: Single unidirectional channel — polarity matters. The cathode band on the DO-201 package must face the rail being protected; reverse insertion leaves the circuit exposed.

Through-hole DO-201 — board-fit note

Axial-leaded DO-201AA / DO-27 package — the body is 9.1 mm long with 0.96 mm diameter leads. The hole pitch on the PCB should match the lead spacing; the leads are soldered on the opposite side of the board. Tape & Reel (TR) or Cut Tape (CT) packaging is available for the reel quantity.

Frequently asked questions

Where can I buy the 1.5KE24A-T and how do I get a price?

The 1.5KE24A-T is obsolete and sourced through independent distribution.

What is the closest pin-compatible alternative to the 1.5KE24A-T?

A functionally similar 1500 W unidirectional TVS in a DO-201 package with a 20.5 V standoff voltage would require a parametric search — no direct pin-compatible replacement is confirmed.
