RCA TRANSISTOR MANUAL SILICON RECTIFIERS INTI98R Hermetically sealed 20-ampere . types for use at peak reverse voltages 1 N1i9 8 R A up to 600 volts. They are used in gener- ator-type power supplies in mobile equipment; de-to-de converters and 4 battery chargers; power supplies for aircraft, marine, and missile equipment; transmitters, rf generators, and dc-motor power supplies; machine-tool controls; welding and electroplating equipment; de- blocking service; magnetic amplifiers, and a wide variety of other heavy-duty applications. These types are reverse-polarity versions of types 1N1198 and 1N1198A, respectively. JEDEC No. DO-5 package; outline 3, Outlines Section. SILICON RECTIFIER Hermetically sealed 12-ampere 1 N11 99 A type for use at peak reverse voltages up to 50 volts. It is used in generator- type power supplies in mobile equip- ment; de-to-de converters and battery Isl ehargers; 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.
