Product details

Obsolete — sourcing through independent channels

The 1.5KE350CA-E3/54: No official successor order code is recorded on the lifecycle notice. If a board spin is acceptable, a functionally equivalent 1500 W bidirectional TVS in the same DO-201AA footprint from another manufacturer may serve as a drop-in — confirm the clamping voltage and breakdown window against the original design.

1500 W peak pulse — what the rating means

The 3.1 A peak pulse current at the clamping voltage tells you the diode can absorb a substantial transient without failing short. Above that, breakdown starts at 333 V minimum, and the clamping voltage caps at 482 V — the protected circuit sees no more than 482 V across the transient.

Through-hole DO-201AA axial package

The wide range means derating for ambient temperature is minimal until you approach the upper limit.

Frequently asked questions

What package does the 1.5KE350CA-/54 come in?

It is a through-hole axial-lead package, specifically DO-201AA (also known as DO-27). The leads are tin-plated copper and solder into standard plated through-holes.

Can I hand-solder the 1.5KE350CA-/54?

Absolutely — the DO-201AA axial package is one of the easiest to hand-solder. The leads are thick enough to hold in place while you solder, and the body is large enough to handle with fingers or tweezers. No hot air or reflow oven needed.
