I'm using the TPD2E001 part in my design to protect an IC from overvoltage. The voltage (DC) is generated within the application (not externally, such as ESD).
The electrical path is as follows: Connector -> 15k resistor -> IC pin.
The TPD2E001 IO pin is connected between the 15k resistor and the IC (on a pin that needs to be protected). High DC voltage is applied at the connector.
Peak voltage: 5kV
Length of pulse: ~20ms
Peak current: 330mA
Pulse characteristic: capacitive discharge (DC) (RC decay waveform)
Duty cycle: once every 2 minutes (max)
Can this part be used this way for overvoltage protection? What is the maximum length of the pulse that is OK for this part to handle?
