Product specification
UHF power transistor
BLT53
FEATURES
Emitter-ballasting resistors for an
optimum temperature profile
Gold metallization ensures
excellent reliability
Withstands full load mismatch.
DESCRIPTION
NPN silicon planar epitaxial transistor
encapsulated in a 4-lead SOT122D
studless envelope with a ceramic cap.
It is designed for common emitter,
class-B operation in portable radio
transmitters in the 470 MHz
communications band. All leads are
isolated from the mounting flange.
