AEC-Q101 — the automotive reliability gate
The SMAJ22AQ-13-F: AEC-Q101 qualification means this TVS passed the stress tests required for automotive-grade discrete semiconductors: high-temperature reverse bias, temperature cycling, and ESD/latch-up screening.
400W peak pulse — clamping at 35.5V
The 22V reverse standoff voltage means it stays transparent on a 24V nominal rail, only conducting when a transient pushes the line above the 24.4V minimum breakdown threshold. Single unidirectional channel in a DO-214AC (SMA) package — the cathode band marks the protected line side; the anode connects to ground.
DO-214AC footprint — board-fit note
The SMA package (DO-214AC) is a standard surface-mount footprint shared across the SMAJ family. Reel and cut-tape options are available for both production and prototyping. The part is RoHS-compliant per Diodes' standard material declaration.
