Help! 2sk389 soic packaged

bettersimple · 28th April 2007, 09:26 AM

Hello, I bought for a good price a soic-a packaged 2sk389 (or sold as so) here:

http://www.kalcic.it/default.asp?id_categoria=539|540|546&ricerca=&testoricerca=&risultati_max=&pag inacorrente=38&equi=&marca=

In the chip I can read:"K389BL 4u".
I think it's not the Linear System LSK389.
Well, I cannot find this soic-packaged datasheet in internet

You can search anywhere: nothing.

Please, help me to find the SOIC datasheet or the pin assignment (or a way to discover it without killing the fet).

Thank you

2SK389 has never been made in SOIC-A package so it must be the Linear version:

No, it's not lsk389.
I've yet tested the Linear pinout, it's not the same :-(

Indeed strange as Linear marks the chips as -A, -B or -C, not -BL, -GR or -V.

I have no idea what you have bought.
