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.
