Product details

400W peak pulse, 155V breakdown – SMAJ140CA bidirectional TVS

The 155V minimum breakdown voltage and 140V reverse standoff voltage mean it clamps transients on lines that ride a 140V DC or AC peak bias, with the clamping ceiling at 227V at the rated peak pulse current of 1.76A. The single bidirectional channel protects a single line against both positive and negative surges without needing a series blocking diode — a clean layout choice for AC-coupled or bipolar signal rails.

Surface-mount DO-214AC (SMA) package with a standard solder-reflow profile.
