Question.4
GDT connected for surge protection. Despite GDT’s massive surge capability, the design also includes a small TVS diode downstream.Why does this design include- TVS Diode?
Select Answer
The TVS provides backup in case the GDT physically fails open
The TVS handles the initial fast transient because the GDT takes microseconds to fire — during that delay, the IC is unprotected
The TVS reduces the capacitance seen by the data line
The TVS limits the continuous current through the GDT to prevent follow current
