Packaged in the through-hole T-18 axial format, it suits board-level retrofits or new designs where a soldered-in transient suppressor is preferred over surface-mount. onsemi lists the P6KE51ARL as Obsolete. For BOM lines requiring this exact order code, the supply channel is independent distribution — stock is sourced per RFQ from franchised excess or verified broker inventory. ## Breakdown and clamping window for 48V circuits Minimum breakdown voltage is 48.5V, so the device starts conducting just above the 48V rail. The 70.1V clamp ensures downstream semiconductors rated for 75V–80V see a safe voltage during a surge event.","metaTitle":"P6KE51ARL onsemi Zener TVS Diode 600W Axial Obsolete","metaDescription":"P6KE51ARL onsemi Zener TVS diode, 600W peak pulse, 43.6V standoff, 70.1V clamp.
