BLU11SL - UHF power transistor

Download the BLU11SL datasheet PDF. This datasheet also covers the BLU11 variant, as both devices belong to the same uhf power transistor family and are provided as variant models within a single manufacturer datasheet.

General Description

N-P-N silicon planar epitaxial transistor primarily intended for use in mobile transmitters in the 470 MHz band.

Key Features

  • multi-base structure and emitter-ballasting resistors for an optimum temperature profile.
  • gold metallization ensures excellent reliability.
  • the device can be applied at a PL of max. 1,5 W when it is mounted on a printed wiring board (see Fig.6) without an external heatsink. The transistor has a 4-lead envelope with a ceramic cap (SOT-122D). All leads are isolated from the mounting base. QUICK.
