Product details

1.5kW Zener TVS in a DO-201 axial package

The 1.5KE12A-T is a 1500W Zener transient voltage suppressor from Diodes Incorporated, designed to clamp transients on general-purpose power and signal lines. The DO-201AA axial package (also known as DO-27) is a through-hole form factor suited for point-to-point wiring or PCB mounting with lead bending.

Diodes Incorporated lists the 1.5KE12A-T as obsolete. For a BOM line that requires a 1.5kW Zener TVS with a 10.2V standoff in a DO-201 package, the 1.5KE12A-T remains orderable through surplus and broker inventory. The peak pulse power and clamping voltage are the critical fit parameters — verify that the 16.7V clamp at 90A stays below the downstream device's absolute maximum rating.

Frequently asked questions

Where can I buy 1.5KE12A-T?

The 1.5KE12A-T is obsolete per the manufacturer. No stock-holding claim is made.

What is the peak pulse power of 1.5KE12A-T?

At that power level, the clamping voltage is 16.7V maximum at 90A peak pulse current.
