RCA TRANSISTOR MANUAL chine-tool controls; welding and electroplating equipment; dc-blocking service; magnetic amplifiers, and a wide variety of other heavy-duty applications. These types are designed to meet stringent environmental and mechanical specifications. The special copper-alloy mounting stud can withstand an installing torque up to 50 inch-pounds. JEDEC No. DO-5 package; outline 3, Outlines Section. Type 1N1197 is used principally for renewal purposes; it is similar to type 1N1197A except for some slightly lower ratings, and ean be directly replaced by type 1N1197A. Type 1N1197A. is identical with type 1N1198A except for the following items: MAXIMUM RATINGS For power-supply frequency of 60 eps, single- phase operation, with resistive or inductive load 500 max volts RMS SUPPLY VOLTAGE. 355 max volts DC BLOCKING VOLTAGE, 500 max volts CHARACTERISTICS Maximum Reverse Current: Dynamic occ eee eee een eee eee een eer eteeenee 2.2 ma * Average value for one complete cycle at maximum peak reverse voltage, maximum average forward amperes, and case temperature = 150C, SILICON RECTIFIERS 1 Nil 9 7R Hermetically sealed types for use at peak reverse voltages up to 500 a 1 Nil 9 7R A volts. They are used in generator-type power supplies in mobile equipment; dc-to-de converters and battery charg- A ers; power supplies for aircraft, marine, and missile equipment; transmitters, rf generators, and de-motor power supplies; machine-tool controls; welding and electroplating equipment; dc-blocking service; magnetic amplifiers, and a wide variety of other heavy-duty applications. These types are reverse-polarity versions of types 1N1197 and 1N1197A, respectively. JEDEC No. DO-5 package; outline 3, Outlines Section.
