Product details

Obsolete TVS — sourcing through independent channels

Diodes Incorporated has marked the P6KE22A-T as Obsolete. For a BOM that already carries this order code, the procurement path is a quoted RFQ against available stock.

600 W unidirectional Zener — clamping and breakdown

The reverse standoff voltage is 18.8 V — the rail it protects must stay below this level during normal operation. The 30.6 V clamp means a 24 V bus sees a transient limited to about 30 V — well within the typical 36 V abs-max of downstream DC-DC converters and linear regulators. The 20 A peak pulse current rating (10/1000 µs waveform) covers moderate surge events on signal or low-power supply lines.

DO-15 axial — board-fit and temperature range

Housed in a DO-204AC (DO-15) axial-lead package, the P6KE22A-T mounts through-hole.

Frequently asked questions

Where can I buy P6KE22A-T and get a price?

No stock-holding or lead-time number is published here.

What is the closest pin-compatible alternative to P6KE22A-T?

No official pin-compatible successor is listed by Diodes Incorporated. A functional replacement would require a TVS with the same package (DO-15 axial), similar standoff voltage (~18.8 V), and 600 W peak pulse power — but a board spin is not needed if the replacement shares the DO-15 footprint and lead bend.
