600W Zener TVS in DO-15 axial — parametric fit for a 5.8V rail
The P6KE6V8A-B: Its 5.8V reverse standoff voltage protects a 5V or 5.8V nominal rail, clamping transients at 10.5V maximum. Breakdown occurs at a minimum of 6.45V, giving margin above the 5.8V working voltage before the diode starts conducting. The 57A peak pulse current rating means it can absorb substantial surge energy from inductive kicks or ESD events on a low-voltage bus. Housed in the DO-204AC (DO-15) axial leaded package, it mounts through-hole — a straightforward fit for point-to-point wiring or PCB layouts that need a robust transient clamp without surface-mount reflow.
Obsolete — sourcing through independent channels
Diodes Incorporated has marked the P6KE6V8A-B as Obsolete. No official successor or second-source part number is listed by the manufacturer. For existing BOM lines, availability is limited to surplus and broker inventory.
Temperature range and general-purpose duty
No power line protection feature — it is a pure transient suppressor, not a rail clamp with integrated filter. Classed for General Purpose applications, it suits power supply input protection, relay coil suppression, and signal line clamping where a through-hole axial package is acceptable.
