The 13 V reverse standoff means it sits across a 12 V rail without conducting leakage in normal operation; the breakdown starts at 14.4 V min, and the clamping voltage hits 21.5 V max at the 18.6 A peak pulse current. That 21.5 V ceiling is what the downstream IC sees during a surge — keep it under the abs-max of the protected part. For shorter pulses (8/20 µs, common in ESD testing), the diode handles significantly more peak current before the junction temperature limit is reached. The single bidirectional channel covers one signal pair or one power rail. ## Package and board-fit Housed in the DO-214AC (SMA) package, with the supplier device package also designated SMA. This is a standard surface-mount footprint — the same pad layout used by hundreds of TVS and Schottky diodes in this package. Cut Tape suits prototype or low-volume builds. Surface-mount means no through-hole leads to trim or solder on the back side.","metaTitle":"SMAJ13CA-13 Diodes Inc TVS Diode, 400W, 13V, DO-214AC","metaDescription":"SMAJ13CA-13 bidirectional TVS diode, 400W peak pulse power, 13V reverse standoff, DO-214AC (SMA).
