5 pin transistor pair I think

[be80be]

Has anyone seen these I've been looking for a data sheet for them they say SK FTP01 2627 0n them.

Possibly Mosfet with current sense output.
SK South Korea Group.
Max.

I'm thinking the two make a H bridge but the board there on Im not having much luck with these I got the wifi card to work.. But I stuck with these thinking i could make a good H bridge with them If I can figure there pinout..

It has to be a DARLINGTON TRANSISTOR, 5 LEAD

Guess no one ever seen these. still no luck at a datasheet. There in a epson printer.

I remember an article in Silicon Chip magazine, I think, about the construction of an audio amplifier. The transistors used had an integral isolated diode for temperture compensation.

e.g. **broken link removed**

EDIT: Added a link

Added a link.

That's kind of what I've found but I can't find a data sheet for it any where. The board is four layer all i can find out is the gnd and vdd pins.

Here is the Silicon Chip amp: https://www.altronics.com.au/p/k5154-ultra-ld-mk.3-135w-class-ab-audio-amplifier-kit/

The S---K logo is definitely a Sanken trademark. (in USA distributor is Allegro system)
There have always been a slew of Sanken devices used in various consumer devices. Some of which may be slightly modified and purposely stamped with house &/or partial number meant to protect the brand. Used to come across this frequently during my time w/Consumer Electronics.
Specific datasheets will be non-public and to make it worse, they tend to get rid of obsolete device documents rather quickly. I have archived several of their old device catalogs over the years.
Sanken is a supplier for printer industry and that just may in fact be a version of this darlington device?--- disregard the part number and removed pin. https://www.semicon.sanken-ele.co.jp/sk_content/std01p_ds_en.pdf.
Otherwise, it may be listed in the printers service manual---if available?

Dear de80de;
I can not fine datasheet FTP01
ALL like in this page not correct.
are you have any data or pin config?

 

[be80be]

I never could find datasheet

by the looks of the board they are on, they are probably voltage regulators. Sanken does a lot of "oem" parts with part numbers that are unlisted.
