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. -- * Dana H.
