Part Number: LT1004-2.5
Tool/software:
We are looking for an alternate IC for LM285D-2.5. We found LT1004-2.5 should be functionally equivalent, however we need to understand the implications of using only one of the cathode pins from Texas Instruments to be sure (we don’t want them to come back and say “expect 1/4 current capacity if only pin 8 is used” or something like that).
As for the extra cathode pin, typically with a pin configuration like this we would connect the two cathode pins together on PCB FAB Layout. The datasheet doesn’t seem to indicate what those internal connections look like and what the current capacity of each cathode pin is rated for but again this is such a low current application that it would be hard to imagine we would exceed the per pin current spec for the LT1004.
