Electrical Parameters
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.
CO
Off-state Capacitance — typical capacitance measured in off state
di/dt
Rate of Rise of Current — maximum rated value of the acceptable rate of
rise in current over time
dv/dt
IS
Rate of Rise of Voltage — rate of applied voltage over time
Switching Current — maximum current required to switch to on state
Leakage Current — maximum peak off-state current measured at VDRM
Holding Current — minimum current required to maintain on state
Peak Pulse Current — maximum rated peak impulse current
On-state Current — maximum rated continuous on-state current
Peak One-cycle Surge Current — maximum rated one-cycle AC current
Switching Voltage — maximum voltage prior to switching to on state
IDRM
IH
IPP
IT
ITSM
VS
VDRM
Peak Off-state Voltage — maximum voltage that can be applied while
maintaining off state
VF
VT
On-state Forward Voltage — maximum forward voltage measured at rated
on-state current
On-state Voltage — maximum voltage measured at rated on-state current
