I am posting this on behalf of a customer, David :
I need help using the digikey PN SESD7L5.0DT5GOSCT-ND
A Digikey tech forum page on this topic includes this:
However, I don’t think this configuration will work for a PU pin, because the ground diode points directly to the pin.
Attached you will see my sketch of a MCU having a Pull-up pin (PU), connected in series with a 100 Ohm resister to a periodic switch to ground. I want to provide ElectroStatic Discharge (ESD) protection.
- Please confirm the sketch diodes are correctly orientated to achieve ESD protection.
- If correct, please sketch how I would wire the above part to achieve ESD protection.
Feel free to call me at 406-465-3357 if you have questions. Thank you!
