TECHNICAL DATA SILICON RECTIFIER Hermetically sealed 12-ampere type for use at peak reverse voltages " wp to 800 volts. It is used in generator- 1 N I203RA type power supplies in mobile equip- ment; de-to-de converters and battery chargers; power supplies for aircraft, marine, and missile equipment; transmitters, rf generators, and de-motor power supplies; machine-tool controls; welding and electroplating equipment; de-block- ing service; magnetic amplifiers, and a wide variety of other heavy-duty applica- tions. This type is a reverse-polarity version of type 1N1203A. JEDEC No. DO-4 package; outline 2, Outlines Section. SILICON RECTIFIER Hermetically sealed 12-ampere type for use at peak reverse voltages up to 400 volts. It is used in generator- 1 N1 204A type power supplies in mobile equip- Is} ment; de-to-de converters and battery chargers; power supplies for aircraft, marine, and missile equipment; transmitters, rf generators, ancl de-motor power supplies; machine-tool controls; welding and electroplating equiprnent; dc-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.
