Product details

1.5KE400CA A0G — 1500W bidirectional TVS in the DO-201 axial package

The 342V reverse standoff voltage means the rail it protects should stay below that level in normal operation.

Minimum breakdown voltage is 380V; the device starts conducting in avalanche at that threshold. The 548V clamp voltage is the maximum the load sees during the transient — a downstream 600V-rated MOSFET or capacitor has margin. The DO-201AA axial package (DO-27 equivalent) handles the 1500W pulse through its lead-frame and junction size.

Frequently asked questions

What is the 1.5KE400CA A0G used for?

The 1500W peak pulse rating suits industrial power supplies, motor drives, and telecom rectifiers.

What package does the 1.5KE400CA A0G come in?

The DO-201AA axial package (also known as DO-27) with through-hole mounting. The Tape & Box packaging option is for automated insertion equipment.
