600 W peak pulse, 14.5 V clamp — what it protects
The P6KE10CA-T: It clamps transients at 14.5 V maximum when the surge current hits 41 A. The reverse standoff voltage is 8.55 V typical, meaning the diode stays transparent on a 5 V or 8 V rail and only conducts when the line exceeds that threshold. Breakdown starts at 9.5 V minimum.
Obsolete — sourcing through independent channels
Diodes Incorporated lists the P6KE10CA-T as obsolete. Available through independent surplus and broker channels. Quantities are lot-specific; pricing and lead time are confirmed at RFQ. The DO-15 axial package is common, so cross-referencing a functional equivalent from the same P6KE family or a similar TVS series is straightforward — confirm the standoff and clamp voltages match your rail.
