Pls help to find datasheet smd diode p/n S4 66A.?
Pls help to find datasheet for a smd diode (written on its body) p/n
S4
66A
The designator or legend on the pcb is CRxxx(numbers),as we know Q is for transistor,D for diode,etc and CR stand for what component?
Thanks!!
More than likely the S4 66A is a code that is used in lieu of the actual part number because the part number is too long to fit on the smd package. If this is the case (it probably is), the only way to get the actual part number and manufacturer is to ask the maker of the equipment it is in. But you probably can not get to the people who would know, so that would be a dead end. The only thing I can suggest is to find it on the schematic diagram of the equipment that uses the diode and see its function. An engineer should be able to determine the type of diode would be a good replacement.
Sorry I can't be of more help.
