Product details

1.5KE11A-B Zener TVS — 1500 W peak pulse, DO-201 axial

The DO-201AA (DO-27) axial-lead package supports through-hole mounting and is supplied in bulk — a form factor well-suited for high-reliability point-to-point wiring or PCB insertion where surface-mount isn't preferred.

Clamping voltage and transient protection envelope

The 9.4 V standoff rating means the device draws negligible leakage current at normal operating voltages up to that level — it only begins conducting significantly when the transient exceeds the 10.5 V breakdown threshold.

Frequently asked questions

What are the key electrical ratings of the 1.5KE11A-B?

It is a 1500 W peak pulse Zener TVS with a 9.4 V reverse standoff, 10.5 V minimum breakdown, 15.6 V maximum clamping voltage at 9 A peak pulse current (10/1000 µs waveform).

What package does the 1.5KE11A-B come in?

It is supplied in a DO-201AA (DO-27) axial-lead through-hole package, in bulk quantity.
