Google search results imply TO-220FP to be full-pack case. Wikipedia says that TO-220F is full-pack case. Farnell categorizes TO-220F and TO-22FP differently. I'm confused. What is the difference between these two TO-220 case versions?

2015年4月17日 · Where can I find an Eagle model for the TO-220F-4L package? Or something similar? I'm trying to add a KA78RXXC-Series Voltage Regulator and I can't even find another component with the same pins.

If your DMM has a diode test function (diode symbol on the switch or display), try it both ways. With the red on the anode it should show the forward voltage at a relatively low current, so maybe 250 (mV) vs. 600 or so with a regular diode. In the opposite direction it should show overrange. Repeat the test for the other diode in the package. Of course it …
