Selection & Usage Guidelines
1. Choosing the Correct Current Rating
The current marked on the module is the average on-state value, not the continuous RMS operating current. Always leave adequate margin based on your actual working environment:
- Resistive Loads: Apply a 2×–2.5× margin — Actual Current (A) × 2 to 2.5 = Module Nominal Current (A)
- Inductive Loads: Apply a 6×–7× margin — Actual Current (A) × 6 to 7 = Module Nominal Current (A)
2. Heat Sink Requirements
When the actual operating current exceeds 5A, a suitable heat sink must be installed to ensure safe and stable long-term operation. Failure to use an appropriate heat sink may result in overheating and reduced module lifespan.

Frequently Asked Questions
Q: What does the 100A rating on the MDQ100A-16 rectifier bridge module mean?
A: The 100A rating refers to the average on-state current, not the continuous RMS value during long-term operation. For real-world applications, always apply the recommended derating margin: 2×–2.5× for resistive loads and 6×–7× for inductive loads, to ensure stable and safe performance.
Q: Do I need a heat sink with the MDQ100A 1600V rectifier module?
A: Yes. Whenever your actual operating current exceeds 5A, a properly rated heat sink is required. Running the module without adequate heat dissipation at higher currents can cause thermal stress and shorten the component's service life.
Q: What voltage ratings are available for the MDQ100A single-phase rectifier bridge?
A: The MDQ100A series is available in multiple voltage ratings: 600V, 800V, 1000V, 1200V, 1400V, 1600V, and 1800V — allowing you to select the right module for your specific AC-DC conversion requirements.
Q: Is the MDQ100A-16 suitable for inductive loads such as motors?
A: Yes, but inductive loads require a much higher derating margin. For motor or inductive load applications, select a module with a nominal current rating of 6 to 7 times your actual operating current to accommodate inrush and reactive current demands safely.
