RCA TRANSISTOR MANUAL interlead capacitance and coupling to adjacent circuit components. JEDEC No. TO-33 package; outline 18, Outlines Section. This type is electrically identical with type 2N384 except for the collector-characteristic curves, which are the same as for type 2N13895, and a higher common-emitter small-signal forward current- transfer ratio of 90. TRANSISTOR Germanium p-n-p type used in rf 2NI 397 and if amplifier circuits; oscillator, 4 mixer, and converter circuits; and low- level video-amplifier circuits in indus- trial and military equipment. It is used in the design of rf circuits having high input-circuit efficiency, excellent operating stability, good automatic-gain-control capabilities over a wide range of input-signal levels, and good signal-to-noise ratio. The drift-field construction provides low base resistance and collector-transition capacitance, and improves performance at high frequencies. A fourth lead inter- nally connected to the metal case provides integral shielding which minimizes interlead capacitance and coupling to adjacent circuit components. JEDEC No. TO-33 package; cutline 13, Outlines Section. This type is electrically identical with type 2N1023 except for the collector-characteristic curves, which are the same as for type 2N1395, and a higher common-emitter small-signal forward current-transfer ratio of 90. POWER TRANSISTOR Germanium p-n-p type used in a ON] 4l 9? wide variety of switching and ampli- " fier applications in industrial and mili- tary equipment requiring transistors having high voltage, current, and. dis- sipation values. It is used in power- switching, voltage- and current-regulating, de-to-de converter, inverter, power- supply, and relay- and solenoid-actuating circuits; and in low-frequency oscillator and audio-amplifier service. This type is designed to provide satisfactory perform- ance under extreme environmental conditions of temperature, moisture, and altitude; it is stud-mounted to provide positive heat-sink contact, and has a cold- weld seal to insure reliable performance under severe environmental conditions.
