Default smt jfet matching suggestions?

Has anyone tried using the tracer to match smt sized jfets? Just wondering what jigs/adapters could be devised to use in the curve tracer, if any. Any ideas would be very welcome! Thanks.

I use small gator clips to measure sot223. They have adapters, but they are kinda high.

Thanks buzzforb. I assume "kinda high" refers to the price? Can you post or pm me a photo of your setup, just want to verify clip size and wire length (or did you solder pins to the clips and stuck those in the curve tracer?).

Radio shack sells them. As you can see, by flipping the SOT 223, you can have everything flat on a pcb. I have gate and Source clips soldered to pcb trace with drain attached to piece of wire for easy clipping. The board is designed to insert into the tracer inputs with right angle pins. I'll see if I can fish it out of dungeon.

Has anybody tried to trace these power JFETs on locky's device?
I get weird curves when I try to do the transfer functions (i.e. N-JFET Vgs/Id (Fix Vce))

Hi Locky,

Your tracer is no longer available on eBay? Are you out of stock? Will you have some new ones coming soon?

Because ebay only allow me sell 5 item once, When they sell out, I need to list them again, and the ebay link also change.
The lastest ebay link is: http://www.ebay.com/itm/locky-zs-Intelligent-curve-tracer-/111102327920?pt=LH_DefaultDomain_0&hash=item19de36 fc70[/URL]
