600W bidirectional Zener TVS — clamping and breakdown profile
The P6KE250CA-T: The reverse standoff voltage is 214 V, so the device stays transparent on a 214 V DC bus and only conducts when the line exceeds the minimum breakdown of 237 V. The single bidirectional channel handles symmetrical clamping — positive and negative transients are clamped to the same voltage magnitude, which simplifies board layout for AC-coupled signal lines or DC rails that see reverse-polarity events.
DO-15 axial package — through-hole board fit
The DO-15 footprint is a common industry standard — replacement parts from other manufacturers fit the same hole pattern without a board spin.
Obsolete — sourcing through surplus channels
Diodes Incorporated lists the P6KE250CA-T as obsolete. Available through independent surplus and broker channels; each lot is date-code and condition-graded at RFQ.
