New ESD protection series for USB Type-C for system protection

Nexperia has optimised its TrEOS ESD protection diode series for using with USB Type-C interfaces. The new USB3.2 standard presents an optional capacitor at the Rx inputs, so the company has now launched two groups of devices, one that produces extremely high surge robustness for positioning between the capacitor and connector, and a second that has a remarkably low trigger voltage for placement between the capacitor and the system chip. Comments Stefan Seider, product manager at Nexperia: “The options offered by USB Type-C and USB Power Delivery are very attractive: To ensure that end customers can enjoy data speeds of up to 20 Gbps and up to 100 W charging, Nexperia offers two TrEOS protection families that support every protection strategy around the new USB3.2 Rx capacitor for protecting sensitive transceivers against possible fault conditions.” The diodes are packaged in 0603 form factor. Advantages of the very compact, very robust DSN0603-2 (SOD962-2) package is the lack of bond wires, which removes another failure mode and provides the lowest inductance for fastest protection. This package is popular for computing and mobile applications.
