Hello,
For surge protection in a 10/100M Ethernet application, consider NXP's PESD3V3L1BA or PESD5V0S1BA series surge protectors. These devices offer bidirectional protection with low series resistance (1.4 ohms), minimal channel-to-channel resistance (0.03 ohms max), and fast response time to transition from normal operating state to current limiting state. With a peak impulse voltage ADPVantage withstand of up to 40V, they effectively safeguard against excessive voltages and currents during surge events, ensuring protection for high-speed, low-voltage drivers and receivers.
Hi smkalim
For the ESD discrete products had already transferred to Nexperia.
You can directly contact with them for getting support!!
Thanks!
