Zener TVS for 53V rail clamping
The P6KE62ARL is a unidirectional Zener transient voltage suppressor from onsemi, designed to clamp overvoltage transients on a 53V nominal rail (reverse standoff voltage) at 85V maximum clamping. With a minimum breakdown voltage of 58.9V and a peak pulse power rating of 600W (10/1000µs waveform), it protects downstream semiconductors from surges like inductive load dumps or lightning-induced spikes. The T-18 axial package suits through-hole board layouts where leaded retention is preferred over surface-mount.
onsemi lists the P6KE62ARL as Obsolete. For BOM positions needing this exact order code, sourcing runs through independent distribution — we can quote against your required quantity from available inventory.
Parametric fit for 53V rail protection
The 53V reverse standoff voltage means the diode does not conduct during normal operation on a 53V DC bus. When a transient exceeds the 58.9V minimum breakdown, the Zener avalanches and clamps the voltage to 85V maximum, shunting up to 7.1A peak pulse current (8/20µs waveform). The 600W peak pulse rating gives headroom for short-duration surges common in industrial and telecom power supplies.
