600W Zener TVS in a DO-15 axial package
The P6KE15CA-T: Housed in the through-hole DO-204AC (DO-15) axial package, it suits board-level transient suppression where a soldered lead gives mechanical stability over surface-mount alternatives.
Obsolete — sourced through surplus and broker channels
Diodes Incorporated lists the P6KE15CA-T as obsolete. Availability is through independent surplus and broker inventory — each lot is date-code and condition verified at RFQ. For a BOM line that requires this exact clamp voltage and package, the surplus channel is the practical source. Sealed reels with consistent date-codes from a single production run are preferred over mixed-date lots that may have been repackaged.
Key clamping specs for the 12V rail
The 12.8V reverse standoff voltage means the diode stays off below that level — a 12V nominal supply sees no leakage penalty during normal bias. Breakdown triggers at 14.3V minimum, so the diode begins conducting before the rail exceeds its abs-max rating.
