AEC-Q101 and the -55 to 150°C operating range
The SMBJ45AQ-13-F: Qualified to AEC-Q101, the automotive-grade stress test covers temperature cycling, high-temperature reverse bias, and ESD robustness — the part is screened for the reliability profile expected in engine-bay or chassis-domain modules. The junction temperature range spans -55°C to 150°C, so the TVS maintains its breakdown and clamping characteristics across cold cranking and under-hood heat soak without parametric drift.
DO-214AA SMB — footprint and reflow fit
Housed in the standard DO-214AA (SMB) surface-mount package, the SMBJ45AQ-13-F uses the same land pattern as other SMB TVS diodes — no footprint change if cross-referencing within the family. Supplied on Tape & Reel, it feeds directly into a pick-and-place line; the MSL rating (typically Level 1 for this construction) means no pre-bake required before reflow as long as the shelf-life seal is intact.
