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.

FEATURES

• Emitter-ballasting resistors for an optimum temperature profile

• Gold metallization ensures excellent reliability

• Withstands full load mismatch.
