I am trying to figure out how to wire the following diode bridge: W01G-E4/51

Attached is the Digikey symbol, footprint, pic, as well as OEM datasheet pic:

It only has 4 pins, just trying to figure out what each pin is for. I know it has two AC inputs (hot and netural) and a DC output and a ground, but not sure what pin goes to which one?

Ok thank you, this makes sense. I was confused because the "Symbol" I posted above from "Ultra Librarian" seems to represent a Mosfet, when it should show something like this:

I entered it in Ultra Librarian and got '' no symbol available for this part.''
Probabally the reason for your confusion?

Hi,
The symbol is obviously a mistake, it shows 5 pins, NOT the 4 pins for the Full Wave rectifier of that Part No W01G-E4/51

The symbol of that mosfet presented in post #1 appears to have been selected by some AI software that saw the protection diodes and jumped to an incorrect selection. One more example of why AI results need to be checked by HI (Human Intelligence)
