Definition

Maximum voltage across the device at breakdown measured under a

specified voltage and current rate of rise.

Instantaneous current flowing at the breakover voltage (V

BO

).

Minimum current required to maintain the device in the on-state.

Current through the device in the on-state condition.

Voltage across the device in the on-state condition at a specified current (I

T

).

Maximum DC voltage that can be applied to the device while maintaining

it in the off-state condition.

Maximum DC value of current that results from the application of the maximum

off-state voltage.

Rated peak pulse current of specified amplitude and waveshape

that may be applied without damage.

Maximum current and voltage rate of rise the device can withstand without damage.
