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). -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

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. https://www.google.com/search?tbm=isch&q=supertex+logo https://www.google.com/search?tbm=isch&q=siliconix+logo http://freespace.virgin.net/matt.waite/resource/logos/logo4.htm 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). http://www.datasheetarchive.com/dlmain/Databooks-5/Document20316.pdf Matt Roberds

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. Matt Roberds

Win Hill is still lurking. I recently posted my TLP191B Spice model to the LTspice list, and Win responded that he liked it.... apparently he's used the part on occasion. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

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. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

I want one of those. Will they do microprocessors as well ?:-) ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.
