I was looking for a SMD diode to add reverse-polarity protection to a circuit I was designing, and the PMEG3020CPA looked like a good fit with regards to my current and voltage needs.
What confused me is why the data sheet shows two anodes, so I have a few questions about that:
- Are the two anodes meant to be connected? E.g. the two internal diodes would be in parallel. Or should only one be used?
- Are the current and voltage ratings given for each of the internal diodes, or both together?
- Why is it designed or diagramed like this?
I ran into this question about three-terminal diodes but that seemed to be one diode and a floating third pin, which isn't really relevant.
