LTSpice Diode Models Sorted By Forward Voltage

LTSpice includes a bunch of LEDs I’ll never own, so finding a tabulation of their forward voltages helped match them against various LEDs on hand. The table was sorted by the forward voltage at the diode’s rated average current, which wasn’t helpful for my simple needs, so I re-sorted it on the Vf @ If = 20 mA column over on the right:

Part #       Mfg             Is         N      Iavg Vf@Iavg  Vd@If

The currents come from plugging the various constants into the Schockley Diode Equation and turning the crank.

One could, of course, measure the constants for the diodes on hand to generate a proper Spice model, but that seems like a lot of work for what’s basically a blinking LED.
