⚠️ Important Selection & Installation Reminders
1. Current Rating & Derating
The rated current shown on a power module is the average on-state value, not the continuous RMS value during long-term operation. Always leave sufficient margin based on your actual working environment:
- 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 the actual working current exceeds 5A, always install a properly rated heat sink to ensure safe thermal management and long-term reliability of the module.
3. Stock & Bulk Orders
Standard models are kept in stock and ready to ship. For bulk or large-quantity orders, please contact our customer service team to confirm quantities and lead times before placing your order.

Frequently Asked Questions
Q: What is the MD100-16 diode module used for in a photovoltaic system?
A: The MD100-16 rectifier diode module acts as a blocking (anti-reverse) diode in photovoltaic solar panel arrays. It prevents reverse current from flowing back into the solar panels at night or during shading, protecting the panels and connected equipment from damage.
Q: Do I need a heat sink with the MD100-16 module?
A: Yes. If your application draws more than 5A of actual working current, it is essential to mount the MD100-16 on a properly sized heat sink. Without adequate thermal management, the module may overheat, reducing its service life and reliability.
Q: How do I select the correct current rating for my load?
A: For resistive loads, multiply your actual load current by 2 to 2.5 to determine the required module nominal current. For inductive loads (motors, transformers, etc.), multiply by 6 to 7. The MD100-16 at 100A nominal is suitable for resistive applications up to approximately 40–50A actual, or inductive applications up to approximately 14–16A actual.
Q: Is the MD100-16 module available in bulk quantities?
A: Yes. Standard quantities are kept in stock and can be shipped promptly. For large or bulk orders, please contact our customer service team in advance to confirm availability and estimated delivery time.
Q: What is the difference between forward voltage and reverse voltage ratings?
A: The forward voltage rating (1600V) indicates the maximum voltage the diode can sustain in the conducting direction, while the reverse voltage rating (1600V) is the maximum voltage the diode can block without breakdown in the non-conducting direction. Both are rated at 1600V for this module, making it well-suited for high-voltage industrial and solar applications.
