24V rail clamp with AEC-Q101 pedigree
The SMBJ24CAQ-13-F: Its 24V reverse standoff voltage means it sits across the line without conducting under normal operating conditions, only clamping when the line exceeds the 26.7V minimum breakdown threshold. AEC-Q101 qualification and the -55°C to 150°C junction temperature range confirm this part is screened for automotive-grade reliability — the same stress tests (HTRB, H3TRB, temperature cycling) that under-hood electronics see.
Active lifecycle — no LTB clock ticking
The base product number SMBJ24 covers the family; the -13-F suffix denotes the tape-and-reel packaging variant.
