Please log in for more thread options If a diode current is 15 microAmperes (forward), what is the voltage? I need an answer as close to 'real life' as possible. Its a silicone diode, 1N4148 or similar | ||||||||||||||||||||||||||||

Please log in for more thread options This varies alot by the part number. I'll show you how to fish... The datasheet for your part is here: http://www.diodes.com/datasheets/ds12019.pdf If you look under electrical characteristics at "Maximum Forward Voltage", you'll get a worst case. Scrolling down to page two, the first graph tells you exactly what you're after. Also, there are several differenct package types for this diode. Best to lookup the data sheet for the one you're planning on using. Chris | ||||||||||||||||||||||||||||

No, it's not.

As has been said, to find the characteristics of a SPECIFIC part
