Philips Semiconductors Product specification
HF/VHF power transistor BLW86
DESCRIPTION
N-P-N silicon planar epitaxial
transistor intended for use in class-A,
It has a 3/8" flange envelope with a
ceramic cap. All leads are isolated
from the flange.
AB and B operated h.f. and v.h.f.
transmitters with a nominal supply
voltage of 28 V. The transistor is
resistance stabilized and is
guaranteed to withstand severe load
mismatch conditions. Matched
hFEgroups are available on request.
