⚠️ Important Selection & Usage Guidelines
1. Selecting the Right Current Rating
The marked current on a power module represents the average on-state value — not the long-term effective operating current. Always leave sufficient margin based on your actual working environment:
- Resistive Load: Apply a 2× to 2.5× margin — Actual Current (A) × 2~2.5 = Module Nominal Current (A)
- Inductive Load: Apply a 6× to 7× margin — Actual Current (A) × 6~7 = Module Nominal Current (A)
2. Heat Sink Requirement
When the actual operating current exceeds 5A, a suitable heat sink must be installed to ensure safe and reliable operation. Failure to use a heat sink at higher currents may result in thermal damage to the module.
3. Voltage Variants
The default voltage for this fast recovery diode module is 400V. If you require 1200V or 2000V specifications, please browse other listings in the store for those variants.

Frequently Asked Questions
Q: What is the difference between MZ100A400V and MZ160A400V fast recovery diode modules?
A: Both are 400V-rated fast recovery diode (FRD) modules in the M220.58 package. 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).
Q: Do I need a heat sink with this FRD rectifier module?
A: 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.
Q: Can I use this fast recovery diode module in a high-frequency switching power supply?
A: 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.
Q: Is the 400V rating the only option available?
A: The default for this listing is 400V. However, 1200V and 2000V variants are also available in this store. If you need a higher voltage specification, please check the other listings or contact us for assistance.
