  • Technical Passport: Comprehensive documentation for each diode type.
  • Installation Recommendations: Guidelines for proper installation to ensure optimal performance.
  • Video Reviews: Visual insights into the performance and applications of power stud and disc rectifier diodes.

Polarity of Diodes

  • Forward Polarity Diode: Threaded base – Anode, flexible power lead – Cathode.
  • Reverse Polarity Diode: Threaded base – Cathode, flexible power lead – Anode. Indicated by an “X” in the code, e.g., “D161-320X-16”.
  • Polarity Marking: Each diode is marked with a polarity symbol on the case for easy identification.

Technical Specifications

  • Schematic Diagrams and Circuits: Illustrations of diode configurations with Anode and Cathode.
  • Part Numbering Guide, Polarity, Dimensions, and Recommended Coolers: Comprehensive details provided for each diode type.

Rectifying Diodes These diodes are widely used power switches, featuring industry-standard housings that simplify integration into existing equipment. They are housed in sealed ceramic cases to protect the semiconductor elements from environmental factors. Cooling is achieved using air and water heat sinks, and reliable thermal and electrical contact is ensured by adhering to specified tightening torque during assembly. Heat conducting paste is recommended for better heat dissipation.

Features of Rectifier Diodes from LJ-MD:

  • Low static and dynamic losses.
  • High VRRM values.
  • Proven performance in various industries.
  • Voltage ranges from 300 to 4400 V.
  • Current ranges from 100 to 500 A.
  • High resistance to thermal and electrical cycling.
  • Options for natural or forced air cooling.

Quality Guarantee Our company provides a quality guarantee for all diodes. Upon request, we supply a technical passport and a certificate of conformity. The final price of power rectifier diodes is influenced by the voltage class, quantity, delivery terms, manufacturer, country of origin, and form of payment.
