Important Selection Guidelines
The rated current printed on the module represents the average on-state value — not the effective continuous operating current. Always apply an appropriate safety margin based on your actual working environment:
- Resistive Load: Multiply actual current (A) × 2 to 2.5 to determine the required module nominal current rating.
- Inductive Load: Multiply actual current (A) × 6 to 7 to determine the required module nominal current rating.
Heat Sink Requirement
When operating the module at currents exceeding 5A, a properly sized heat sink must be installed to ensure safe, reliable operation and long service life. Please select a heat sink rated for your expected power dissipation.

Frequently Asked Questions
Q: What is the difference between MDS200-16, MDS300A-16, and MDS400-16 rectifier modules?
A: The primary difference is the nominal current rating. MDS200-16 is rated for 200A, MDS300A-16 for 300A, and MDS400-16 for 400A — all share the same 1600V voltage rating. When selecting the right model, apply the appropriate derating factor: 2–2.5× for resistive loads and 6–7× for inductive loads relative to your actual operating current.
Q: Do I need a heat sink with this three-phase rectifier module?
A: Yes. Any time the module operates above 5A, a suitable heat sink is required to dissipate thermal energy and maintain safe junction temperatures. Failure to use an adequate heat sink at higher currents can significantly reduce module lifespan and reliability.
Q: Can this rectifier module be customized for specific applications?
A: Yes, customization is available. Please contact customer service with your specific requirements — including current rating, voltage, and quantity — to discuss options and confirm lead times for custom or bulk orders.
Q: What types of equipment commonly use the MDS series three-phase diode bridge rectifier?
A: The MDS series is widely used in industrial motor drives, welding power supplies, electroplating equipment, battery chargers, CNC machinery, and other applications that require robust AC-to-DC power conversion with high current capacity.
