NE734 Datasheet, PDF (1/5 Pages) NEC – NPN SILICON GENERAL PURPOSE TRANSISTOR
NPN SILICON GENERAL NE734
PURPOSE TRANSISTOR SERIES
FEATURES
• LOW NOISE FIGURE: < 3 dB at 500 MHz
• HIGH GAIN: 15 dB at 500 MHz
• HIGH GAIN BANDWIDTH PRODUCT: 2 GHz
(3 GHz for the NE73435)
• SMALL COLLECTOR CAPACITANCE: 1 pF
• HIGH RELIABILITY METALLIZATION
DESCRIPTION
The NE734 series of NPN silicon general purpose UHF tran-
sistors provide the designer with a wide selection of reliable
transistors for high speed logic and wide-band low noise
amplifier applications. The series uses NEC's highly reliable
platinum-silicide, titanium, platinum, and gold metallization
system to assure uniform performance and reliability. The
30 (SOT 323 STYLE)
35 (MICRO-X)
NE73433 is in the plastic Mini-Mold package designed for
high-speed automated assembly operations for large volume
hybrid ICs. For hybrid MIC applications requiring more perfor-
mance, the NE73435 is recommended. This device is pack-
aged in the economical metal-ceramic, hermetic Micro-X pack-
age.
