Its 600W peak pulse power rating (10/1000µs waveform) and 11.1V reverse standoff voltage make it a fit for 12V vehicle bus protection, where the clamp triggers at 18.2V max. The AEC-Q101 qualification and -65°C to 150°C operating range confirm it can survive under-hood thermal cycling and cold-crank events. The single bidirectional channel simplifies layout — one device protects both polarities on a line. onsemi lists the P6SMB13CAT3 as Obsolete. For an existing BOM position, the only sourcing path is through independent distribution — we can source against an RFQ, confirming date code and provenance before commit. If you are qualifying a replacement, look for a bidirectional TVS in DO-214AA with equivalent 600W rating and 11.1V standoff. The AEC-Q101 grade is non-negotiable for automotive lines — ensure the alternative carries that qualification before swapping. The 33A peak pulse current at 10/1000µs sets the surge handling — enough for ISO 7637-2 pulse 5a on a 12V rail, but check your specific transient profile. The 740pF capacitance at 1MHz is typical for a 600W TVS; it adds about 0.5Ω of impedance at 1MHz, which is negligible for DC power lines but may affect high-speed data lines. If you already have a P6SMB13CA or similar in your library, the land pattern is identical — no PCB spin needed for a like-for-like swap.","metaTitle":"P6SMB13CAT3 onsemi TVS Diode – 600W, AEC-Q101, Obsolete","metaDescription":"P6SMB13CAT3 from onsemi: 600W bidirectional Zener TVS, 11.1V standoff, AEC-Q101, DO-214AA SMB.
