The best way to assure reliability in a low-current rectifier pellet is to put it in a package that really protects it. Protects it from shock, humidity, vibration and temperature. And thats just what we do with General Electric's glassivated 1-amp (A14) and 3-amp (A15) rectifiers. Solid glass provides passivation and protection of the silicon pellets P-N junction no organic material is present within the hermetically sealed package. In addition, rigid mechanical support and ex- cellent thermal characteristics are provided by the dual heat sink construction. For high-frequency applications, GE offers a fast-recovery rectifier, the 1-amp A114, with a 200 nsec. max. reverse recovery. 132Silicon Rectifiers MEDIUM CURRENT 6A TYPE IN1341A-48A IN1341RA-48RA These stud mounted diffused junction silicon rectifiers, (designed to meet MIL-E-1/1108) are recommended for all rectifier applications in the 2 to 8 ampere range. A high junction tem- perature rating and an extremely low forward voltage drop and thermal impedance permit D) high current operation with minimum space requirements. These rectifiers may be mounted directly to a chassis or a fin or may be electrically insulated from the heat sink by using the mica washer insulating kit Versatility is further increased by the availability of a negative polarity unit (stud is anode), described by the suffix R appearing after the type number. The use of positive and negative polarity units facilitates the construction of bridge circuits and permits the use of either a positive or negative heat sink in half-wave and center-tap applications. General Electric research, advanced development and product design have resulted in a highly efficient rectifying junction. This feature, plus a mechanical design employing high temperature hard solders and welds for all internal and external joints and seals, which eliminates common sources of thermal fatigue failure, have produced a silicon rectifier with outstanding reliability under all operating conditions. electrical ratings and specifications (60 eps, Resistive or Inductive Load) IN1341A 1N1342A 1N1343A 1N1344A IN1345A INI346A 1N1347A_ 1N1I348A Max.
