600W Zener TVS in a DO-15 axial body
The P6KE6V8A-T: It clamps at 10.5V max with a 57A peak pulse current capability, making it a fit for protecting 5V logic or low-voltage supply rails against transient overvoltages. The 5.8V reverse standoff voltage means the device does not conduct at normal operating levels up to that point; breakdown starts at 6.45V min. This narrow window suits circuits where the nominal rail sits at 5V with minimal ripple. Housed in a DO-204AC (DO-15) axial-lead package, it mounts through-hole — the body is large enough to dissipate the pulse energy without a heatsink, and the axial leads make it straightforward to hand-replace on a board if it ever takes a hit that exceeds its rating.
Obsolete — sourcing through independent channels
Diodes Incorporated lists the P6KE6V8A-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 enough that a parametric substitute from another manufacturer may fit the same board footprint — confirm the standoff voltage and clamping spec against the BOM requirement.
