The reverse standoff voltage of 78V means the diode does not conduct below that level — it sits as a high-impedance shunt across the protected line until a transient exceeds the minimum breakdown voltage of 86.7V. ## Package and board-fit for SMA footprint Housed in the DO-214AC (SMA) package, this surface-mount diode suits automated pick-and-place assembly. The SMA footprint is standard across the industry — the same pad layout serves equivalent TVS parts from multiple manufacturers, easing second-source qualification.","metaTitle":"SMAJ78CA-13 Diodes Inc TVS, 78V Standoff, 400W, DO-214AC","metaDescription":"SMAJ78CA-13 bidirectional TVS diode, 78V reverse standoff, 400W peak pulse, DO-214AC SMA.
