TYPICAL SWITCHING CHARACTERISTICS
NOTE 1
The switching characteristics shown above were measured using a test cir-
cuit similar to Figure 5. At the beginning of the switching interval, the gate
voltage is at Gate Supply Voltage (VGG). The DrainSource Voltage
(VDS) is slightly lower than Drain Supply Voltage (VDD) due to the voltage
divider. Thus Reverse Transfer Capacitance (Crss) or GateDrain Capaci-
tance (Cgd) is charged to VGG + VDS.
During the turnon interval, GateSource Capacitance (Cgs) discharges
through the series combination of RGen and RK. Cgd must discharge to
VDS(on) through RG and RK in series with the parallel combination of ef-
fective load impedance (R
D) and DrainSource Resistance (rds). During
the turnoff, this charge flow is reversed.
Predicting turnon time is somewhat difficult as the channel resistance
rds is a function of the gatesource voltage. While Cgs discharges, VGS ap-
proaches zero and rds decreases. Since Cgd discharges through rds, turnon
time is nonlinear. During turnoff, the situation is reversed with rds in-
creasing as Cgd charges.
The above switching curves show two impedance conditions; 1) RK is
equal to RD, which simulates the switching behavior of cascaded stages
where the driving source impedance is normally the load impedance of the
previous stage, and 2) RK = 0 (low impedance) the driving source imped-
ance is that of the generator.

NOTE 2
The ZeroGateVoltage Drain Current (IDSS), is the principle de-
terminant of other J-FET characteristics. Figure 10 shows the
relationship of GateSource Off Voltage (VGS(off) and Drain
Source On Resistance (rds(on)) to IDSS. Most of the devices will
be within
10% of the values shown in Figure 10. This data will
be useful in predicting the characteristic variations for a given
part number.
For example:

rds(on) and VGS range for an J112
The electrical characteristics table indicates that an J112 has
an IDSS range of 25 to 75 mA. Figure 10, shows rds(on) = 52 Ohms
for IDSS = 25 mA and 30 Ohms for IDSS = 75 mA. The corre-
sponding VGS values are 2.2 volts and 4.8 volts.
