Automotive TVS for 24V rail protection
The SMAJ24AQ-13-F: Its 24V reverse standoff voltage means it stays transparent below that threshold and only starts conducting when the line exceeds it, protecting downstream electronics from load-dump and surge events.
AEC-Q101 qualification and temperature range
This part carries AEC-Q101 automotive qualification — the stress-test and reliability baseline for discrete semiconductors used in under-hood, chassis, and cabin electronics. The junction temperature range spans -55°C to 150°C, covering the full automotive thermal envelope from cold-crank to engine-bay soak.
Clamping and pulse current performance
At the 10/1000µs pulse waveform, the clamping voltage maxes out at 38.9V while the device handles a peak pulse current of 10.3A. The 26.7V minimum breakdown voltage defines the avalanche threshold — the diode starts clamping just above the 24V rail, leaving minimal overshoot before full conduction.
Housed in the DO-214AC (SMA) package, the SMAJ24AQ-13-F is a surface-mount device with a low-profile footprint suited for automated assembly. The SMA body is a standard JEDEC outline — the pad geometry and solder stencil aperture are well-documented, with no exotic reflow profile requirements.
