CAN and LIN Lines Don’t Fail from Load – They Fail from Charge

Even the best designs can fail. Shielded cables, flawless routing - everything looks perfect… until a single static discharge strikes. One transient can push 30 kV through a line designed for 5 V logic. And when that happens, software recovery alone isn’t enough.

The NUP3105L-AQ from Diotec protects your lines right at the interface:

· <100 nA leakage current

· Up to 30 kV ESD protection

· Ultra-low 30 pF capacitance

· AEC-Q101 qualified, PPAP capable

· 295 W peak power dissipation (8/20 µs)

This bidirectional dual diode in a compact SOT-23 package safeguards two lines without adding distortion.

Because reliable communication isn’t just about how signals move… it’s about how they survive.
