RCA TRANSISTOR MANUAL SILICON RECTIFIER Hermetically sealed 12-ampere INT 20 5 A type for use at peak reverse voltages a up to 500 volts. It is used in generator- type power supplies in mobile equip- ment; de-to-de converters and battery yk chargers; power supplies for aircraft, marine, and missile equipment; transmitters, rf generators, and de-motor power supplies; machine-tool controls; welding and electroplating equipment; dce-block- ing service; magnetic amplifiers, and a wide variety of other heavy-duty applica- tions. This type is designed to meet stringent environmental and mechanical specifications. The special copper-alloy mounting stud can withstand an installing torque up to 25 inch-pounds. JEDEC No. DO-4 package; outline 2, Outlines Section.
