The 64.8V clamp ceiling limits the voltage seen by downstream silicon, and the 9.3A peak pulse current rating (10/1000µs) defines the surge it can absorb before the junction overheats. Capacitance is 220pF at 1MHz, which is moderate — suitable for low-speed signal lines or power rails, but may load high-frequency data buses beyond a few MHz. onsemi has marked the P6SMB47CAT3 as Obsolete. For BOM sustainment, buyers should plan for last-time buys or identify a form-fit-function replacement from the same P6SMB family (base product number P6SMB) with matching voltage and bidirectional configuration.","metaTitle":"P6SMB47CAT3 onsemi Zener TVS, 600W, AEC-Q101, DO-214AA","metaDescription":"onsemi P6SMB47CAT3 Zener TVS diode, 600W peak pulse, 40.2V standoff, AEC-Q101 qualified.
