Both seem to be Obsolete They are Common Anode Diode Pairs
8A per diode 16a total and 600v TO220 case

 

What is the application (how fast does it need to be?)?

 

@N11778
Would this work for you?

Pin 2 needs to be Common Anodes

Close but no Cigar. Here is the PinOut.

You'll have to go with a TO-247 package and fold the pins in a bit when you mount it. 0.2" pin spacing.

He's going to have to do more than fold the pins to turn a common cathode device into a common anode device .

Interesting, Digikey's parametric search and summary page lists it as common anode - but you are right (if the datasheet is correct.

Not Sure How fast is has to be im sure it could be slower a bit
its for my Harbor Freight 2000w Inverter
