NXP Semiconductors Product specification
N-channel FETs
PMBF4391;
PMBF4392; PMBF4393
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
Note
1. Drain and source are
interchangeable.
Marking code
1 = drain
2 = source
3=gate
PMBF4391 = p6J
PMBF4392 = p6K
PMBF4393 = p6G
