What test did you have in mind?

A typical performance parameter is the 1mA 'threshold' conduction voltage - which is sort of easy to test. It is much harder the larger conduction current-voltage, as it needs to be a pulse test, due to power dissipation. But you may be interested in capactince?

Ciao, Tim
