Definition

Off-state Capacitance - typical capacitance measured

in off state

On-state Voltage - maximum voltage measured at

rated on-state current

Peak Off-state Voltage - maximum voltage that can

be applied while maintaining off state

Switching Voltage - maximum voltage prior to

switching to on stat

On-state Current - maximum rated continuous

on-state bcurrent

Holding Current - minimum current required to

maintain on state

Leakage Current - maximum peak off-state current

measured at VDRM

Switching Current - maximum current required to

switch to on state
