    TVS Selection for JTAG IF

    user_80002741

      Hello, I'm doing a design with a PSoC5 CY8C5888AXQ-LP096 microcontroller on my board with a JTAG interface for debug/programming.

      I am powering the device with 3.3V. I'm using a TVS Diode on pin 1 of the JTAG connector. The TVS I have chosen has the following specs:

      Voltage Reverse Standoff 3.3V
      Voltage Breakdown 5V
      Voltage Clamping max 14.1V

      Current Peak Pulse 11.2A (8/20µs)

       

      Does this TVS Diode (part# CPDQ3V3-HF) sound like a good fit for the design?

       

      Thanks,

      Joe
