Philips Semiconductors
N-channel FETs
DESCRIPTION
Symmetrical silicon n-channel
depletion type junction field-effect
transistors on a plastic
microminiature envelope intended for
application in thick and thin-film
circuits. The transistors are intended
for low-power chopper or switching
applications in industry.
PINNING
1 = drain
2 = source
3 = gate
Note
1. Drain and source are
interchangeable.
Marking code
PMBF4391 = p6J
PMBF4392 = p6K
PMBF4393 = p6G
QUICK REFERENCE DATA
Drain-source voltage
Drain current
VDS = 20 V; VGS = 0
Gate-source cut-off voltage
VDS = 20 V; ID = 1 nA
Drain-source resistance (on) at f = 1 kHz
ID = 0; VGS = 0
Feedback capacitance at f = 1 MHz
−VGS = 12 V; VDS = 0
Turn-off time
VDD = 10 V; VGS = 0
ID = 12 mA; −VGSM = 12 V
ID = 6 mA; −VGSM = 7 V
ID = 3 mA; −VGSM = 5 V
