The key difference is current capacity — the MZ100A400V is rated up to 100A maximum forward current, while the MZ160A400V supports up to 160A. Choose based on your circuit's load current and apply the recommended derating margin (2–2.5× for resistive loads, 6–7× for inductive loads).\u003c\/p\u003e\n\u003ch4\u003eQ: Do I need a heat sink with this FRD rectifier module?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. Any time the actual operating current exceeds 5A, a heat sink is required. The M220.58 package is designed to mount directly to a heatsink surface for optimal thermal dissipation. Operating the module above 5A without a heat sink risks thermal damage and premature failure.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this fast recovery diode module in a high-frequency switching power supply?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The MZ Series FRD modules are specifically designed for fast recovery applications, making them well-suited for high-frequency switching power supplies (SMPS), inverters, and similar circuits where a standard rectifier diode would introduce excessive reverse recovery losses.\u003c\/p\u003e\n\u003ch4\u003eQ: Is the 400V rating the only option available?\u003c\/h4\u003e\n\u003cp\u003eA: The default for this listing is 400V.
