Capacitance is 120 pF at 1 MHz, which loads the signal line – relevant for high-frequency or fast-switching circuits where added capacitance may degrade edge rates. ## Package and mounting – DO-214AA SMB Surface-mount package DO-214AA (SMB), supplied in Tape & Reel. The SMB footprint is common across the P6SMB series, so a board layout designed for the P6SMB91A or similar SMB-packaged TVS accepts this part without modification.","metaTitle":"P6SMB91CAT3 onsemi TVS Diode – Obsolete, AEC-Q101, 600W","metaDescription":"onsemi P6SMB91CAT3 bidirectional Zener TVS, 600W peak pulse, 77.8V standoff, AEC-Q101 automotive qualified, DO-214AA SMB.
