BLU11

DISCRETE SEMICONDUCTORS DATA SHEET BLU11/SL UHF power transistor Product specification July 1986 http://www.Datasheet4U.com Philips Semiconductors Product specification UHF power transistor DESCRIPTION N-P-N silicon planar epitaxial transistor primarily intended for use in mobile transmitters in the 470 MHz band. 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 REFERENCE DATA R.F. performance in a common-emitter class-B circuit. MODE OF OPERATION narrow band; c.w. T °C Tmb = 25 Ta = Note 1. Device mounted on a printed wiring board (see Fig.6).
