It clamps a 17.1V nominal rail to 27.7V maximum at 22A peak pulse current, which is the surge profile you size the downstream DC-DC or load switch for. onsemi lists the P6SMB20CAT3 as Obsolete. For BOM lines that still call out this exact order code, procurement runs through independent distribution — we source and quote per RFQ against your quantity, with date-code and lot traceability verified before shipment. ## 17.1V standoff, 490pF capacitance — rail and signal-line fit With a reverse standoff of 17.1V, this TVS sits on a 12V or 15V automotive rail without conducting leakage at nominal voltage. The 490pF capacitance at 1MHz is moderate — acceptable for DC power and low-speed signal lines, but too high for a high-speed CAN or Ethernet data pair where you would reach for a low-capacitance TVS array. The bidirectional channel means no polarity concern on AC or floating lines — one part covers both halves of the waveform.","metaTitle":"P6SMB20CAT3 onsemi Zener TVS Diode — Obsolete, AEC-Q101","metaDescription":"P6SMB20CAT3 is obsolete from onsemi.
