CL01-12D High Voltage Rectifier Diode, 12kV 350mA High Voltage Silicon Rectifier Diode for Compact High Voltage Modules & Industrial Power Supplies
The CL01-12D High Voltage Rectifier Diode is a compact, high-performance silicon diode engineered for reliable high-voltage rectification in space-constrained electronic systems. With a 12kV repetitive peak reverse voltage (VRRM), 350mA average forward current, and 30A surge current capability, it is designed to provide outstanding electrical stability, low leakage current, and long operational life.
Compared with standard axial high-voltage diodes, the CL01-12D features a miniature Φ5 × 9 mm package, making it ideal for compact high-voltage modules, PCB assemblies, electrostatic equipment, and portable power supplies where installation space is limited.
As a professional high voltage rectifier diode manufacturer, we provide OEM and ODM solutions for industrial, medical, and scientific high-voltage applications.
