Product details

Obsolete — sourced per RFQ

The 1.5KE18CA-T is marked Obsolete by Diodes Incorporated.

1500 W peak pulse, 15.3 V standoff

Breakdown occurs at 17.1 V min, so the device starts clamping before the transient exceeds the downstream component's abs-max rating.

DO-201 axial, through-hole mount

Supplied in a DO-201AA / DO-27 axial-lead package, through-hole mount. The Tape & Reel format suits automated insertion for volume builds. The bidirectional configuration means a single device protects both polarities — no need to series two unidirectional parts.

Frequently asked questions

How can I order 1.5KE18CA-T or check availability?

The 1.5KE18CA-T is obsolete. We source it through independent distribution; submit an RFQ for current availability and pricing. No stock-holding claim — confirmed at quote time.

What is the closest pin-compatible alternative to 1.5KE18CA-T?

A functionally similar 1500 W bidirectional TVS with a 15 V standoff in a DO-201 package may serve as a replacement, but pinout and footprint should be verified against the original BOM position.
