600W Zener TVS for 102V automotive rails
It delivers 600W peak pulse power per the 10/1000µs waveform, clamping at 165V max with a 3.6A peak pulse current rating. AEC-Q101 qualification makes this part suitable for automotive environments where reliability screening is mandatory — think ECU power inputs, sensor supply lines, or actuator driver rails exposed to load-dump and inductive kickback.
onsemi lists the P6SMB120AT3 as Obsolete. For BOM positions that require this exact order code, procurement must source through independent distribution or the spot market. The base product number P6SMB covers a wide voltage range; a functionally equivalent part with the same package and power rating but a different voltage may be available in the active P6SMB series. Confirm the standoff voltage and clamping spec against the application before substituting.
DO-214AA (SMB) surface-mount package
The SMB footprint is standard across the P6SMB series, so a layout designed for this part can accept other voltage variants without board revision.
