BLT53
BLT53 is UHF power transistor manufactured by NXP Semiconductors.
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 mon emitter, class-B operation in portable radio transmitters in the 470 MHz munications band. All leads are isolated from the mounting flange. PINNING
