Selection & Installation Guidelines
1. Current Margin Selection
The rated current value represents the average on-state value, not the continuous RMS operating value. Always leave adequate margin based on your actual load:
- Resistive loads: Actual current (A) × 2 to 2.5 = Required module nominal current (A)
- Inductive loads: Actual current (A) × 6 to 7 = Required module nominal current (A)
2. Heat Sink Requirement
When operating above 5A continuous load, a suitable heat sink must be fitted to the module to ensure safe and stable long-term performance. Failure to use a heat sink under high-current conditions may result in thermal degradation.

Frequently Asked Questions
Q: What is the difference between the 55A rated current and my actual operating current?
A: The 55A rating is the average on-state forward current. For safe, reliable operation, you should apply a derating factor — multiply your actual operating current by 2–2.5× for resistive loads, or 6–7× for inductive loads, and select a module rated at or above that value. This ensures sufficient thermal and electrical margin.
Q: Do I need a heat sink with the M220.58 diode module?
A: Yes. For any application where the continuous operating current exceeds 5A, a properly sized heat sink is required. This maintains safe junction temperatures and ensures long-term module reliability.
Q: What voltage configurations are available for the M220.58 module?
A: The M220.58 rectifier diode module is available in 12V, 24V, 48V, 600V, 800V, 1000V, 1200V, and 1600V configurations, making it suitable for a wide range of photovoltaic, industrial, and power electronics applications up to 1800V reverse voltage.
Q: Can I order this diode module in bulk or with custom specifications?
A: Yes. Standard models are available in stock for immediate purchase. For bulk orders or custom configurations, please reach out to our customer service team with your required quantities and specifications to confirm availability and lead times.
