IDSS, ZERO-GATE VOLTAGE DRAIN CURRENT (mA)

Figure 10. Effect of IDSS on Drain−Source

Resistance and Gate−Source Voltage

NOTE 2

The Zero−Gate−Voltage Drain Current (IDSS) is the

principle determinant of other J−FET characteristics.

Figure 10 shows the relationship of Gate−Source 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.

rDS(on) and VGS range for an MMBF4392

The electrical characteristics table indicates that an

MMBF4392 has an IDSS range of 25 to 75 mA. Figure

10 shows rDS(on) = 52 W for IDSS = 25 mA and 30 W for

IDSS = 75 mA. The corresponding VGS values are 2.2 V

and 4.8 V.
