600 W Zener TVS — the scorch-mark tells you
The P6KE62AG: When a spike exceeds the 58.9 V breakdown minimum, the Zener clamps the rail at 85 V max, shunting up to 7.1 A (8/20 µs pulse).
53 V standoff — what it protects
With a 53 V reverse standoff voltage, this TVS sits on a 48 V nominal rail (battery, telecom, industrial DC bus) and stays transparent until the transient arrives. The 58.9 V breakdown minimum means it does not conduct during normal ripple. The 85 V clamping ceiling limits the voltage the downstream circuitry sees — a 600 W pulse at 85 V means the part absorbs about 7 A before the silicon gives out.
onsemi lists the P6KE62AG as Obsolete. The axial package is a through-hole leaded form factor that rework labs can hand-solder without a hot-air profile.
