VHF power transistor BLV12
FEATURES
• Emitter-ballasting resistors for an
optimum temperature profile
• Excellent reliability
• Withstands full load mismatch.
DESCRIPTION
NPN silicon planar epitaxial transistor
encapsulated in a 4-lead SOT123
flange envelope with a ceramic cap. It
is designed for common emitter,
class-B operation in mobile VHF
transmitters with a supply voltage of
12.5 V. All leads are isolated from the
mounting flange.
