Power Rectifier Diode Д271 Series (D271 Series)

Introducing our LJ-D271 series of Rectifier Stud Diodes, meticulously engineered to deliver exceptional performance and reliability across a wide range of applications. From LJ-D271-250 to LJ-D271-500X, each diode variant in this series is designed to handle high currents and voltages with precision and efficiency. With robust construction and advanced features, our LJ-D271 series ensures optimal operation and longevity in demanding environments.

The polarity of the diode is indicated by a symbol on the case: the threaded base serves as the Anode for forward polarity, while the flexible power lead acts as the Cathode. Conversely, for reverse polarity, the threaded base becomes the Cathode, and the flexible power lead becomes the Anode. Notably, forward polarity is not specified in the part numbering, while reverse polarity is marked with an “X” in the part numbering.

Featuring a hermetic ceramic housing that isolates the functional part and semiconductor element from mechanical impacts and environmental factors, these stud screw-fit diodes with flexible power leads are suitable for use on moving parts. Specifications, parameters, datasheets PDFs, sample technical passports, dimensions, outline drawings, case diagrams, and recommended heat sinks are available below.
