Why is the forward current of 3-chip operation less than forward current of 1-chip operation? (Page 3 of datasheet.)



1 Answer 1


Power dissipation, the package can dissipate a set amount of heat, in page 4 there is a table showing the thermal resistance for 1 chip and 3 chip operation

in other words, you have the dissipation capacity of the chip to the package which limits the power to a single chip and then the resistance of the package which limits the power to the whole device
