IEC 62680-1-3:2022

Overview

IEC 62680-1-3:2022 is an international standard defining the USB Type-C® cable and connector specification. It sets the global benchmark for USB Type-C receptacles, plugs, cables, and detection mechanisms designed to support data and power transmission. This specification ensures seamless interoperability between new USB Type-C connectors and existing USB silicon solutions, while emphasizing user-friendly features such as reversible plug orientation and simplified connections.

This standard, issued by the International Electrotechnical Commission (IEC) in collaboration with the USB Implementers Forum (USB-IF), replaces the previous 2021 edition and integrates key updates like the Extended Power Range (EPR) aligned with USB Power Delivery Specification R3.1 V1.0. It is essential for designers and manufacturers aiming to develop compliant USB Type-C products supporting enhanced power and data capabilities.
