A humble question about the 2N3904 transistor

[dip]

Is there an IC that has 2N3904 transitor in it? I have to use an IC instead of transistors so I was wondering what is it's IC equivalent?

Tnx.

What do you mean "IC" equivalent? The SMT equiv should be something like mmbt3904, or pzt3904. 2n3904 refers both to the case style (to-92 footprint) and the semiconductor material. If you search Fairchild, Vishey, ST, etc using the parametric option you'll probably come up with something. Or search the mmbt/pzt PN's if SMT is what you need. What package are you looking for anyway?

If you need multiple xstors in a dip type package you'll most likely have to do the parametric search using the 3904 characteristics.

Good luck.

IC = Integrated Circuit. I have to use a Darlington array in my ckt but my prof says use an IC. Geh...

Thanks anyways :)

I know "IC" mean integrated circuit; however, you needed to specify which package you needed. There are not a lot of "IC's" containing a single xstr which was why I asked.

Needing a darlington array is different than needing a 3904. Go to Mouser electronics and search for darlington array. You'll find many "ICs" for about $1.50 that will meet your requirements. Darlingtons are exceedingly common as ICs.

Ok, thanks

More importantly how the device is to be used. Switch? Amplifier? The 2003 (can't think of prefix) is a darlington switch. It is capable of a couple of hundred mA I believe. There are 7 darlington pairs on the device. It is typically used as a relay driver or similar application.
