- USB 2.0 layout: 90 Ω differential, and where the TVS goes
The impedance, the length match, the capacitance budget and the order of the protection parts — with the numbers and the documents each one comes from.
- How to choose and place a TVS diode for ESD protection
Why a 5 V TVS hands the pin 10 V mid-strike, which datasheet numbers predict it, and the placement rules that stop loop inductance adding 40 V per nanohenry.
