2.2 Electrical characteristics
2.2.1 Main circuit
2-4
Term Symbol Description
Collector Current at off
signal input
I
CES
Leakage current when specified voltage is applied between the
collector and emitter and all input signals are "H" (=all IGBTs are
turned-off).
Collector-Emitter saturation
voltage
V
CE(sat)
Voltage drop between the collector and emitter when gate input
signal is "L"(=IGBT is turned-on).
Forward voltage of FWD V
F
Voltage drop across the FWD at defined forward current at input
signal is "H" (=IGBT is turned of).
Turn-on time
t
on
The time from when the input signal drop below the input
threshold value
V
inth(on)
until the collector current of IGBT become
above 90% of predetermined current.
Refer to Figure 2-1.(page 2-7)
t
d(on)
The time from when the input signal drop below the input
threshold value
V
inth(on)
until the collector current of IGBT become
above 10% of predetermined current. Refer to Figure 2-1.
Turn-off time
t
off
The time from when the input signal rise above the input
threshold value

inth(off)
until the collector current of IGBT become
10% of predetermined current. Refer to Figure 2-1.
t
d(o
ｆｆ
)
