NTE6048 thru NTE6073 Industrial Silicon Rectifier 70 Amp, DO5
 
Description: The NTE6048 thru NTE6073 power rectifiers are stud mounted DO5 packages. Because the silicon junction is carefully fitted within a glass−to−metal hermetically sealed case, reliable operation is assured, even with extreme humidity and under other severe environmental conditions. These power rectifiers are completely corrosion resistant.
 
A double diffused, passivated junction technique is utilized to provide stable uniform electrical characteristics, Inherent in their design are very low leakage currents and excellent surge handling capability. These NTE power rectifiers are available in both anode−to−case and cathode−to−case polarity in offering extended application parameters.
 
NTE silicon power rectifiers are ideal for a broad range of commercial uses including power supplies, ultrasonic systems, inverters, welders, emergency generators, battery chargers, DC motor, and motor controls
