600W Zener TVS — 70.1V standoff, 113V clamp
The P6KE82ARL: Its 70.1V reverse standoff voltage and 113V maximum clamping at 5.3A peak pulse current make it suitable for protecting 48V to 72V DC rails from transients such as inductive kickback or lightning surge coupling. The 77.9V minimum breakdown voltage ensures the device starts conducting before the protected circuitry's absolute maximum rating is reached, while the 113V clamp holds the voltage below typical semiconductor breakdown thresholds for downstream components.
Housed in an axial through-hole package, the P6KE82ARL is suited for point-to-point wiring or PCB mounting where surface-mount is not practical. The axial leaded format allows manual or wave-solder assembly.
Sourcing is limited to independent distribution channels where date-code consistency and lot traceability must be verified — the laser etch on the body is a forensic fingerprint that should match the manufacturer's marking standard for the production week. No official successor part is recorded in the ledger. Buyers should evaluate alternative TVS diodes with equivalent 70.1V standoff and 600W peak pulse rating in the same axial package, or consider surface-mount equivalents if board rework is acceptable.
