So I was browsing digikey and came across this rectifier.
I tried search the catalog for the "other half" (to make a bridged rectifier) but I cannot find it. Is this specifically designed for a full-wave rectifier?
Thanks in advance.

I was curious so I looked on digikey. One example is a MUR1620CTRG. I found it pretty easily by going to diode arrays filtering on Diode configuration common anode. There were many but only a few in TO-220 form.
Most SMPS use this for the positive supply from ferrite transformer.
Negative is usually two ordinary diodes soldered in reverse polarity relative to diagram above.
So there may be a supply issue.
But why, simply use Schottky / FR bridge or single diodes.

It would be a centre-tapped trafo and thus it gives full-wave rectification but only of a single (positive) polarity.
For 50/60Hz analog supplies, you just want to buy a bridge. This (usually) avoids the mounting insolation issue.

This above scheme was common in PC AT supplies...
+12V and +5V used such devices, and -12V was two ordinary FR or Schottky diodes.
