The SMAJ170CAQ-13-F: The minimum breakdown voltage is 189V, providing a 19V margin above the 170V standoff before the diode begins to conduct — enough headroom to ride through normal rail transients without nuisance clamping.
The SMA package has a low profile and standard pad layout, compatible with reflow soldering profiles used for most automotive PCB assemblies.
The SMAJ170CAQ-13-F is an active part sourced through authorized and independent distribution.
The part is AEC-Q101 qualified for automotive applications. RoHS and REACH compliance documentation is typically available from Diodes Incorporated; confirm at RFQ.
