Looking for a transistor IC, I believe

[siongboon]

Hi,

I was searching for a soic wide 8 pins
IC with the following print on it.
"C5664
016
637"

Wonder if anyone is experience enough to
know what is the part number of this IC.
I tried to search the web, but nothing come close.
I believe it is MOSFET or similar kind of transistor.
Pin 2,3,4 are shorted.
Pin 5,6,7,8 are shorted too.

If possible I would also like to know if there
are other similar transistor with the same type of pin out.
I would like to try them out.

Thank you for your help.

Based on the way pins are shorted, I would say it is a MOSFET.
There are many types out there, but you need to know if it's an N-channel or a P-channel.

For MOSFETs go to the IR, Fairchild, Vishay or ON Semi website and do a search for MOSFETs in SOIC-8 package.

Try to search 2SC5664. It is common that 2SC 2SD transistor come without the first two characters printed on it
