Automotive-grade transient suppression for 16V rails
The SMBJ16AQ-13-F: Qualified to AEC-Q101, this part is specified for the -55°C to +150°C junction temperature range — the full automotive temperature envelope covering under-hood and engine-bay environments where 125°C ambient is routine and 150°C junction is the survival limit.
Clamping voltage and breakdown margin
The 17.8V minimum breakdown voltage sits 1.8V above the 16V standoff, giving a 11% guard band against normal rail transients before the diode starts conducting — enough margin to avoid nuisance clamping on a regulated 16V bus while still catching overvoltages early. At 26V maximum clamping, the TVS holds the protected node below the typical 30V abs-max rating of downstream 16V-rated ICs and modules, ensuring the surge energy is shunted before the load fails.
Package and board integration
Housed in the DO-214AA (SMB) surface-mount package, the SMBJ16AQ-13-F occupies a standard footprint shared across the SMBJ series — the same pad layout accepts any voltage variant in the family, simplifying BOM rotation for different rail voltages. Supplied on Tape & Reel (TR) with Cut Tape (CT) option, the part is ready for high-volume pick-and-place assembly; the SMB package's JEDEC-standard solder profile matches typical lead-free reflow without special handling.
