Important Selection & Usage Notes
1. Choosing the Right Current Rating
The rated current of this power module reflects the average on-state current, not the continuous RMS operating value. Always leave adequate margin based on your actual working environment:
- Resistive Load: Apply a 2–2.5× margin — Actual Current (A) × 2 to 2.5 = Module Nominal Current (A)
- Inductive Load: Apply a 6–7× margin — Actual Current (A) × 6 to 7 = Module Nominal Current (A)
2. Heat Sink Requirement
When the operating current of the device exceeds 5A, fitting a suitable heat sink is strongly recommended to maintain safe thermal performance and maximize the lifespan of the module.
3. Stock & Bulk Orders
Standard models are typically in stock and ready to ship. For bulk or large-quantity orders, please contact customer service with your required quantity to confirm lead times and delivery schedules.

Frequently Asked Questions
Q: What is the difference between the MDQ100A1600V and MDQ150A1600V rectifier bridge modules?
A: Both modules operate at a maximum reverse voltage of 1600V, but they differ in current capacity. The MDQ100A1600V supports up to 100A average forward current, while the MDQ150A1600V supports up to 150A. Choose based on your load requirements, applying the recommended derating margins for resistive or inductive loads.
Q: Do I need a heat sink with this single-phase rectifier bridge module?
A: Yes. For any application where the operating current exceeds 5A, a heat sink is strongly recommended. Proper thermal management is essential to maintain performance, prevent overheating, and extend the service life of the module.
Q: Can this AC-DC rectifier module be used for inductive loads such as motors?
A: Yes, this module is suitable for inductive loads. However, when sizing the module for inductive loads, apply a 6–7× derating margin over your actual operating current to ensure reliable and safe long-term operation.
Q: Is the MDQ100A/150A rectifier bridge module customizable for bulk orders?
A: Yes. Customization options are available. For bulk or special orders, please contact customer service with your quantity and requirements to confirm specifications and delivery timelines.
