These diodes work in power supplies, industrial converters, motorové pohony, svařovací stroje, a invertory. They manage high voltage and current in systems needing stable rectification. The spiral design ensures efficient cooling, making them ideal for environments with frequent thermal fluctuations.

What is the difference between forward and reverse models?
The 25HF120 is a forward rectifier, guiding current in one direction during AC-to-DC conversion. The 25HFR120 operates in reverse, blocking reverse voltage spikes to protect circuits. Using both models in a system balances efficient power conversion and safeguards against voltage surges.

Why choose a spiral structure over standard diodes?
The spiral cathode increases surface area, spreading heat evenly and reducing hot spots. This design improves thermal resistance and current capacity. Standard planar diodes may fail under similar stress due to uneven heat buildup. The spiral type handles higher surge currents without damage.

How do I install these diodes correctly?
Mount the diodes on a heatsink using proper thermal paste. Tighten screws evenly to avoid mechanical stress. Follow torque specifications in the datasheet. Ensure polarity matches the circuit requirements—forward diodes for conversion, reverse diodes for protection. Incorrect installation risks overheating or circuit failure.

What safety precautions are necessary?
Use insulated tools to prevent short circuits. Check for cracks or damage before installation. Avoid exceeding maximum voltage or current ratings. Test diodes with a multimeter to confirm functionality. Store in anti-static packaging when unused. Proper handling ensures longevity and prevents operational hazards.
