onsemi lists the P6KE160ARL as Obsolete. For BOM positions that still call this order code, the only practical path is independent-distribution sourcing — confirmed against the RFQ quantity and date-code requirements.
600 W Zener TVS — 136 V standoff, 219 V clamp
It is rated for 600 W peak pulse power with a reverse standoff voltage of 136 V and a maximum clamping voltage of 219 V at the peak pulse current of 2.7 A (8/20 µs waveform). The 152 V minimum breakdown voltage defines the threshold where the device starts conducting — below that the protected rail sees no added leakage.
The part carries no power-line protection rating, so it is intended for signal or low-voltage DC rail clamping — not AC mains surge suppression.
