Electrical Parameters
Electrical parameters are based on the following definition of conditions:
On state (also referred to as the crowbar condition) is the low impedance condition
reached during full conduction and simulates a short circuit.
Off state (also referred to as the blocking condition) is the high impedance condition prior
to beginning conduction and simulates an open circuit.

rise in current over time
