Automotive TVS options ahead of the regulator

Table

PartPackageManufacturerWhy it stands out
SMCJ24A-QSMCBournsBest balanced choice for the 12 V input ahead of IC1
SM8S24A-QDO-218BournsHeavier-duty option if you want more surge margin at the 39514-5004 entry
SMBJ28A-QSMBBournsSmaller package option if space matters more than surge robustness
SMBJ26A-QSMBBournsSimilar compact automotive option
SMCJ24AQ-13-FSMCDiodesReasonable alternative to the Bourns SMC part
Recommendation Placement
  • Put the TVS directly behind the 39514-5004, from +12 V to GND, before the input path feeding IC1.
If you want, I can next find a matching reverse-polarity protection part for the same input path.
