Its 18.8V reverse standoff voltage and 20.9V minimum breakdown voltage make it a fit for clamping transients on 15V to 18V DC rails in automotive electronics. ## Clamping and capacitance at 1 MHz Maximum clamping voltage is 30.6V at the rated 20A peak pulse current. The 835pF typical capacitance at 1 MHz is high enough to slow fast edges; for high-speed data lines, a lower-capacitance TVS would be preferred. ## Obsolete — sourcing for legacy BOMs onsemi lists the P6SMB22AT3 as Obsolete.","metaTitle":"P6SMB22AT3 Zener TVS Diode – 600W, AEC-Q101, DO-214AA (SMB)","metaDescription":"P6SMB22AT3 is an obsolete onsemi Zener TVS diode with 600W peak pulse power, 18.8V reverse standoff, AEC-Q101 qualified.
