BLU20

DISCRETE SEMICONDUCTORS DATA SHEET BLU20/12 UHF power transistor Product specification August 1986 Philips Semiconductors UHF power transistor Product specification BLU20/12 DESCRIPTION N-P-N silicon planar epitaxial transistor primarily intended for use in mobile radio transmitters in the 470 MHz communications band. FEATURES multi-base structure and emitter-ballasting resistors for an optimum temperature profile gold metallization ensures excellent reliability. internal matching to achieve an optimum wideband capability and high power gain. The transistor has a 6-lead flange envelope with a ceramic cap (SOT-119). All leads are isolated from the flange. QUICK REFERENCE DATA Envelope Mode of operation Collector-emitter voltage (d.c.)
