The 14V standoff voltage sits just above a nominal 12V battery line, so the diode stays transparent during normal operation and only clamps when a transient pushes the rail above 15.6V breakdown. Housed in a DO-214AC (SMA) surface-mount package — the same footprint as standard SMA diodes, so no layout change if swapping from a generic SMAJ14A. No power line protection feature — this is a unidirectional TVS for signal or low-side power rail clamping, not for AC mains. The single unidirectional channel protects one rail per device. The base product number is SMAJ14, and the full order code SMAJ14AQ-13-F includes the automotive Q-grade suffix.","metaTitle":"SMAJ14AQ-13-F TVS Diode, 400W, 14V, DO-214AC, AEC-Q101","metaDescription":"SMAJ14AQ-13-F is an automotive-grade 400W TVS diode from Diodes Inc, 14V reverse standoff, DO-214AC SMA package.
