Germanium and Schottky diodes have the lowest Vf. Silicon rectifiers (1N4004, etc) are higher, small-signal diodes (1N4148) are higher than that and PIN diodes (BA283) are higher still. Then come the LEDs.

Touch the black probe, connected to COM on the multimeter to the negative (-) terminal of the battery.... WebIf your meter has a designated “diode check” function, use that rather than the “resistance” range, and the meter will display the actual forward voltage of the PN junction and not just whether or not it conducts current. Meter readings will be exactly the opposite, of course, for an NPN transistor, with both PN junctions facing the other way.
Web3 mrt. 2011 · The forward voltage is the voltage drop across the diode if the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode). You will be using this value to calculate …
