MD Series 1000V Rectifier Diode Module 5A–150A Anti-Reverse
MD Series 1000V Rectifier Diode Module 5A–150A Anti-Reverse
MD Series Rectifier Diode Module — 1000V, 5A to 150A
The MD Series Rectifier Diode Module is a compact, high-performance solution for power electronics applications requiring reliable unidirectional current flow. Available in a wide range of current ratings — from 5A up to 150A — and rated at 1000V, these modules are engineered for demanding industrial, automation, and power conversion environments. The small form factor (M220.58 package) makes them ideal for space-constrained designs without sacrificing electrical performance.
Made in Mainland China.

⚠️ Important Selection & Usage Guidelines
1. Current Rating Selection
The rated current of a power module represents the average on-state value, not the continuous RMS operating value. Always apply an adequate safety margin based on your actual working environment:
- Resistive Load: Multiply actual current (A) × 2 to 2.5 to determine the required module nominal current rating.
- Inductive Load: Multiply actual current (A) × 6 to 7 to determine the required module nominal current rating.
2. Heat Sink Configuration
When the actual operating current exceeds 5A, a suitable heat sink must be installed to ensure safe, stable long-term operation and to prevent thermal damage to the module.
3. Custom Voltage Options
Standard stock modules ship at the default 1000V rating. If your application requires 12V, 24V, 600V, 1200V, 1600V, or 1800V variants, please contact our customer service team with your order quantity and specifications to confirm production lead times. Volume discounts are available for mass customization orders.

Frequently Asked Questions
Q: What current ratings are available for the MD Series Rectifier Diode Module?
A: The MD Series is available in the following current ratings: 5A, 10A, 20A, 25A, 30A, 40A, 50A, 70A, 90A, 100A, 110A, and 150A — all at a standard 1000V voltage rating. Custom voltage variants (12V, 24V, 600V, 1200V, 1600V, 1800V) are also available on request.
Q: Do I need a heat sink with this rectifier diode module?
A: Yes. If your operating current exceeds 5A, a properly sized heat sink is required to maintain safe operating temperatures and protect the module from thermal stress during continuous use.
Q: How do I choose the right current rating for my application?
A: For resistive loads, select a module rated at 2–2.5× your actual operating current. For inductive loads (motors, solenoids, etc.), select a module rated at 6–7× your actual operating current to ensure reliable, long-term performance with adequate margin.
Q: Can I order a custom voltage version of the MD Series Rectifier Module?
A: Yes. While the standard in-stock version is rated at 1000V, custom voltage configurations (12V, 24V, 600V, 1200V, 1600V, and 1800V) are available. Please contact our customer service team with your required specifications and order quantity to confirm pricing and lead times.
Q: What package type does the MD Series Rectifier Module use?
A: The MD Series uses the compact M220.58 module package, which is designed for easy mounting and integration into power control boards and industrial panels.
