Plot and compare diode forward currents vs. voltage

There are many devices for which different spice models or subcircuits are available.

Although they are for the same basic device they may have different I vs. V curves.

This may be because the devices are in fact different from different manufacturers or because they have been measured and modelled under differet conditions.

This simulation shows an easy way to compare the current vs. forward voltage curves for a selection of diode models.
