Jenene cece eee rene eet eeeneeete 32 db POWER TRANSISTOR Germanium p-n-p type used in a QINI173 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, dc-to-de converter, inverter, power- supply, and relay- and solenoid-actuating circuits; and in low-frequency oscillator and audio-amplitier 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 reliabie performance under severe environmental conditions.
