What this TVS protects and how it clamps
The 1.5SMBJ20CA-H: It clamps transients at 32.4 V maximum when the surge current hits 46.3 A, and its 20 V reverse standoff voltage means it stays transparent on a 20 V nominal rail until a spike exceeds the 22.2 V minimum breakdown threshold. AEC-Q101 qualification places it in the automotive-grade tier — the part is screened for the -55°C to +150°C junction temperature range and the reliability stress tests required for under-hood and chassis-mounted electronics.
