Mystery Part -- Si VN01?

Question

I was digging through le junque bocs yesterday looking for a TO-92 MOSFET, and found a bag of what I dimly remember as being such.

But my memory is too dim, and I used a PN2222 with a base resistor instead.

So before I throw these out, can anyone recognize the part? If I know what it is I can mark the bag and have it as a resource. Otherwise I'll probably trash it.

It's a TO-92 package, has three lines printed:

Si VN01

8209

It's probably some horribly obsolete Siliconx thing that should never be used for design, but le junque bocs isn't for that -- it's there for slapping together some quick thing for an experiment when simulation won't do, or for a lab setup (yesterday it was an MC14013 flip-flop pretending to be a 2:1 gear reduction from an index pulse, but I forgot just how wimpy 4000 series CMOS is, so I needed an output driver).

It isn't in my 1989 Siliconix Low Power Discretes book--the lowest  number there is the VN10KM.  But it'll be an N-channel VMOS device.

Is the 'i' inside the 'S' or next to it? One site suggests that an 'S' with an 'i' next to it is actually Supertex, but I'm not sure how much I trust this.

This page of an old Siliconix data book shows several Supertex parts with numbers of the form VN010[4689]N[1-6]. The sixth digit is the voltage/10 (40 to 90 V) and the final digit varies with the case style (3 is TO-92).

Hey... the VN01 is in AoE! Pages 122-123 in the 2nd edition. There is even a graph of Vgs vs Id: linear from 0.8 to 2 V at 1 nA to about

50 mA, and then rising quickly: about 3 V at 100 mA and 8 V at 1 A.

Thanks guys. Bag is back with the transistor stash, with a note as to what the parts really are.

Maybe I'll actually use one before we can just get 3D printers that make circuit boards, complete with ICs.
