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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do I need a heat sink with this three-phase rectifier module?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this rectifier module be customized for specific applications?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, customization is available.
