We are looking for the surge protector in unidirectional and bi-directional mode. Can you suggest the part from NXPs portfolio if it matches the technical specifications?

High speed protectors are the TVS devices to form an extremely low let-through energy barrier to excessive voltages and currents during surge events which may cause damage to unprotected high-speed, low voltage drivers and receivers. components.

They are used in multiple applications but we need a 10/100M ethernet application.

Current required for the device to go from operating state to protected state- 750mA
Series resistance-1.4Ohms
Chanel to channel resistance-0.03ohms max
Time for the device to go from normal operating state to current limiting state - 50ns
Peak impulse voltage withstand with duration less than 1 ms - 40V max

Hi smkalim

For the ESD discrete products had already transferred to Nexperia.

You can directly contact with them for getting support！！

Thanks!

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.
