Minimum breakdown voltage is 53.2 V, with a typical standoff of 47.8 V — the margin between standoff and breakdown is 5.4 V, which gives the protected line headroom during normal operation while still triggering clamping before damage occurs. Capacitance at 1 MHz is 365 pF, which is low enough for moderate-speed signal lines but too high for high-frequency data buses like CAN FD or 100BASE-T1 without additional filtering. Confirm the package (DO-214AA SMB) and polarity (unidirectional) match your PCB layout before committing.","metaTitle":"P6SMB56AT3 onsemi Automotive TVS – Obsolete, AEC-Q101, 600W","metaDescription":"P6SMB56AT3 from onsemi – Automotive AEC-Q101 Zener TVS, 600W peak pulse, 77V clamp, DO-214AA SMB.
