Zener TVS in a through-hole axial — 600W pulse, 8.55V standoff
It clamps transients at 14.5V maximum, with a reverse standoff voltage of 8.55V and a minimum breakdown of 9.5V.
onsemi lists the P6KE10ARL as Obsolete.
Replacement path — P6KE10A or equivalent
The base product number P6KE covers multiple breakdown voltage options. The closest drop-in replacement is the P6KE10A — same 600W rating, same T-18 axial package, same 8.55V standoff and 14.5V clamp. No pinout change — the axial leads are identical. For a surface-mount alternative, the SMBJ10A or SMCJ10A in a DO-214AA or DO-214AB package offers similar electrical specs but requires a board layout change.
Temperature range and mounting — hand-solderable axial
The T-18 axial body is through-hole mount — easy to hand-solder on a perfboard or replace in a repair.
