D71-300-40-R0-KWK High Voltage Power Recovery Diode 4000V 40A for HV DC Power Supplies

A premium component tailored for high-voltage DC (HV DC) power supplies, the D71-300-40-R0-KWK redefines reliability and efficiency in high-voltage scenarios.​

With a robust 4000V (4kV) rated voltage and 40A continuous forward current, it effortlessly endures the high-voltage, high-current demands of HV DC systems—ensuring stable operation without breakdown or performance loss under heavy loads.​

As a dedicated power recovery diode, it excels at reclaiming excess energy and redirecting it back to the system, slashing power dissipation, reducing heat generation, and boosting overall energy efficiency. This not only cuts operational costs but also extends the lifespan of HV DC power supply setups.​

Engineered with high-quality materials and strict manufacturing standards, it offers excellent thermal stability and corrosion resistance, performing reliably across diverse environments—from industrial HV DC conversion and renewable energy systems (solar/wind inverters) to medical high-voltage equipment (CT scanners, X-rays) and grid-tied power distribution.​

For HV DC power supplies that prioritize high voltage handling, efficient energy recovery, and long-term dependability, the D71-300-40-R0-KWK is the optimal choice.​
