The -65°C to 150°C junction temperature range covers under-hood and engine-bay environments, but the 600W peak pulse rating must be derated above 25°C per the datasheet curve. For a 48V nominal rail, the 53V reverse standoff provides margin; the 58.9V minimum breakdown ensures the device starts clamping before the rail exceeds the downstream IC's absolute maximum. ## Package and footprint — DO-214AA SMB Surface-mount in DO-214AA (SMB) package. The SMB footprint is standard — 0.050-inch pitch, cathode band on the body. The 335pF capacitance at 1MHz is typical for a 600W Zener TVS; it does not load a 1MHz signal line but may affect high-speed data lines above 10MHz.","metaTitle":"P6SMB62AT3 onsemi Zener TVS – Obsolete, AEC-Q101, 600W","metaDescription":"P6SMB62AT3 onsemi Zener TVS diode, AEC-Q101 qualified, 600W peak pulse, 53V standoff, DO-214AA SMB.
