Is that a 2N7000E (no gate protection) ? The E series devices have recently been discontinued, and I've been debating with myself whether to buy a reel or two before they're all gone.

I don't know. We have several sources listed as suppliers for 2N7000 and 7002. We don't use them in leakage-critical apps. The one that I pulled from stock had amazing gate leakage behavior, hours with little drift.
I also don't know what part Win tested for drain current.

2N7000, 2N7002 has (had) no gate protection.

Depends on the model. Current production is all gate-protected AFAIK.

I tried a 2N7000 from stock, Fairchild, which could be old. I got +100 volts on the gate without significant gate current, but a subsequent drain test suggests that I may have damaged something.

You're right--looks it's just the Vishay ones that are gate protected. Guess I won't worry about it then. ;)
