Short 36.4 KB PDF datasheet named for SM6004 with a 6 suffix, likely a variant or a second part related to the SM6004; the manufacturer and function are not given in the name. The small size points to a concise sheet with pinout and main electrical data. It can be read in any PDF viewer and used to identify pins for voltage and signal checks during fault finding. A separate, larger SM6004 document exists in this index, so compare both and confirm which marking appears on the chip.
