PRODUCTION DATA
The first level of protection starts at the Type-C connector and the VBUS pin capacitors. These capacitors help filter out high frequency noise but can also help absorb short voltage transients. Each VBUS pin should have a 10-nF capacitor rated at or above 25 V and placed as close to the pin as possible. The GND pin on the capacitors should have very short path to GND on the connector. The derating factor of ceramic capacitors should be taken into account as they can lose more than 50% of their effective capacitance when biased. Adding the VBUS capacitors can help reduce voltage spikes by 2 V to 3 V.
