N-channel FETs BSR56; BSR57; BSR58
DESCRIPTION
Symmetrical silicon n-channel
depletion type junction field-effect
transistors in 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 industrial service.
