Part Number: ESD451

Hi @ti team,

Currently we are planning to use ESD451DPLR in the GNSS antenna path near to the on board UFL connector to which a 3.3V supported active antenna is going to get connected. Can you please let me know whether this diode is suitable for the same.

    Hi Sai,

    Short answer is yes, this diode is suitable.

    The 3.3V is lower than the diode VRWM. I would also look at the insertion loss graph just to make sure this is okay. Insertion loss is low for the frequencies GNSS use (around -2.5dB). Look at the graph below. 

    Let me know if you have any questions.

    Best,

    Bryan
