FOR ERICSSON COMPONENTS 3357/3 DCLIC
DECEMBER 1995 - REVISED SEPTEMBER 1997
Repetitive Peak Forward Current, IFRM
Rated maximum (peak) value of a.c. power frequency forward current of specified waveshape and frequency
which may be applied continuously.
Critical rate of rise of on-state current, di/dt, (diT/dt)cr
Rated value of the rate of rise of current which the device can withstand without damage.
main terminal characteristics
Off-State Voltage, VD
The d.c. voltage when the device is in the off-state.
Off-State Current, ID
The d.c. value of current that results from the application of the off-state voltage, VD.
Repetitive Peak Off-State Current, IDRM
The maximum (peak) value of off-state current that results from the application of the repetitive peak off-state
voltage, VDRM.
Breakover Voltage, V(BO)
The maximum voltage across the device in or at the breakdown region measured under specified voltage rate
of rise and current rate of rise.
NOTE - Where a breakdown characteristic has several V(BO) values that need to be referenced, a numeric
suffix can be added and the relevant part of the breakdown current range specified (e.g. V(BO)1,
0 < I(BR) < 10 mA).
Holding Current, IH
The minimum current required to maintain the device in the on-state.
Off-State Capacitance, CO, CJ
The capacitance in the off-state measured at specified frequency, f, amplitude, Vd, and d.c. bias, VD.
Peak Forward Recovery Voltage, VFRM
The maximum value of forward conduction voltage across the device upon the application of a specified
voltage rate of rise and current rate of rise following a zero or specified reverse-voltage condition.
Critical rate of rise of off-state voltage, dv/dt, (dvD/dt)cr
The maximum rate of rise of voltage (below VDRM) that will not cause switching from the off-state to the on-
state.
Breakover Current, I(BO)
The instantaneous current flowing at the breakover voltage, V(BO).
Switching Voltage, VS
The instantaneous voltage across the device at the final point in the breakdown region prior to switching into
the on-state.
Switching Current, IS
The instantaneous current flowing through the device at the switching voltage, VS.
On-State Voltage, VT
The voltage across the device in the on-state condition at a specified current IT.
