Product details

Clamping and peak pulse ratings for the automotive bus

The SMAJ22CAQ-13-F: The 24.4 V minimum breakdown voltage means the device starts conducting just above the 22 V rail, protecting downstream electronics from transients without nuisance triggering on normal supply ripple.

Automotive grade and temperature envelope

Qualified to AEC-Q101, the SMAJ22CAQ-13-F is specified for the -55°C to +150°C junction temperature range — covering under-hood and engine-bay thermal profiles where ambient can exceed 105°C on a summer grade.

DO-214AC SMA footprint and reflow integration

The bidirectional single-channel configuration eliminates orientation concerns during pick-and-place: the diode clamps equally on positive and negative transients, simplifying BOM management for unipolar and bipolar rails.
