Its 12.2 V minimum breakdown voltage means it starts conducting just above the normal operating level, and the 18.2 V clamping voltage at 22 A peak pulse current (10/1000 µs waveform) limits the spike the downstream circuitry sees. Rated for 400 W peak pulse power, this part handles the kind of short-duration surges common in general-purpose industrial and consumer power inputs — think a relay kickback or a hot-plug transient on a 12 V bus. ## Active lifecycle, no EOL pressure The 11 V standoff voltage and 400 W rating are the key BOM-fit parameters to confirm against the protected rail and the expected surge energy.","metaTitle":"SMAJ11A-13 Diodes Inc TVS, 11V Standoff, DO-214AC","metaDescription":"SMAJ11A-13 Diodes Inc Zener TVS diode, 11V reverse standoff, 400W peak pulse, DO-214AC SMA.
