Transistors in DIP?

Not sure what series this is

- NPN or PNP bipolar or - FETs

small-signal transistors in through-hole DIP package.

Where should I start looking?

The only one I know off off-hand is the MPQ2222, a quad array of

2N2222-type NPN transistors.

This part appears to be obsolete. You might find a few at surplus dealers, or at the big $100-minimum-order IC consolidators. Blue Star seems to have a couple of dozen in stock at $2 each (ouch!)

If you're thinking of going into production with parts like this, I think you'll probably decide to redesign using more modern surface-mount arrays. There seems to be little demand for DIP-type arrays any more, and parts cost and availability are likely to become an even worse problem in the future.

If you only need a handful, search around, or just make your own using DIP headers and discretes.

Common parts meeting your very vague outlines:

ULN2003A = 7 darlington-connected NPN pairs, all the emitters common.

CA3046 = 5 NPN's, pretty well matched, 2 of them connected as a differential pair

CD4007 = 3 pairs of N and P channel transistors, one hooked up like an unuffered CMOS inverter, the other two pairs with independent drains and sources

At one point there also existed arrays of 4 2N2222's or 4 2N3906's etc. in a DIP but I haven't seen these in years. In fact the CA3046 I mention above isn't very common anymore either.

Not sure what you mean !

I suggest forgetting it. There's very little like that. There was stuff like the CA3086.

Wow, it seems Intersil still have it.

Seems to me I saw a whole lot of stuff that used the 3046 and 3086 over the years.

4 matched NPNs in a DIP14
