Zener TVS diode for 160V rail protection
Breakdown voltage is guaranteed at 178V minimum, meaning the device starts conducting and clamping above that threshold.
The base product number SMBJ160 covers the whole family, so future BOM revisions can stay within the same footprint.
Bidirectional single-channel layout
A single bidirectional channel protects one signal or power line against both positive and negative transients. No polarity concern during placement — the same device works for AC-coupled lines or DC rails where reverse polarity is a risk.
