ST’s dataline overvoltage protection devices for IEC 61000-4-5 compliance feature:
- Small packages including flip-chip, SOD and µQFN
- Optimized characteristics to provide robustness, flexibility and immunity to protect against surge currents on datalines
They support specific applications such as power over Ethernet (PoE), gigabit Internet, industrial sensors, metering and battery chargers for portable devices.
