- I don't think you've ever seen a germanium 1N4148. That's a JEDEC
- registration for a silicon diode. I'm certain you've seen germanium
- diodes, but not germanium 1N4148s. Anyway, the forward voltage is around
- .6V. It will increase with increased forward current, and it will decrease
- with increased junction temperature. I've seen it range from .55V to .65V
- under normal circumstances.
