The 4.8 A peak pulse current rating reflects the current that the 600 W rating sustains into a 125 V clamp — a useful sanity check when estimating the surge capacity into a given source impedance. onsemi lists the P6KE91ARL as Obsolete. For a BOM line that requires this exact order code, sourcing runs through independent distribution or surplus channels. Through-hole axial package, supplier device package Axial. This covers cold-start outdoor cabinets and hot under-hood automotive environments without derating the peak pulse power — the 600 W rating is specified at 25°C; derate linearly above that per the datasheet curve.","metaTitle":"P6KE91ARL onsemi 600W Zener TVS – Obsolete, Sourcing Info","metaDescription":"P6KE91ARL onsemi Zener TVS diode, 600W peak pulse, 86.5V breakdown min, T-18 axial package.
