78V bidirectional TVS for 400W surge clamping
The SMAJ78CA-13: With a peak pulse power rating of 400W (10/1000µs waveform), it absorbs surges up to 2.2A while clamping at 126V maximum. 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.
