⚠️ Important Selection & Usage Notes
1. Choosing the Right Current Rating
The rated current on each module reflects the average on-state value — not the continuous effective operating value. Always select a module with adequate margin for your actual working conditions:
- Resistive Load: Actual current (A) × 2 to 2.5 = Module nominal current (A)
- Inductive Load: Actual current (A) × 6 to 7 = Module nominal current (A)
2. Heat Sink Configuration
When the actual working current exceeds 5A, always pair this module with an appropriately rated heat sink to ensure safe, stable long-term operation and to protect the module from thermal damage.
3. Stock & Bulk Orders
Standard MDK models are available in stock for immediate shipment. For bulk or large-quantity orders, please contact our customer service team to confirm quantities and delivery timelines before placing your order.
For guidance on safe electrical component installation and handling, refer to the OSHA Electrical Safety Standards.
Frequently Asked Questions
Q: What current ratings are available for the MDK 1600V rectifier diode module?
A: The MDK series is available in the following current ratings: 26A, 40A, 55A, 75A, 90A, 110A, 135A, 160A, 182A, 200A, 250A, and 300A — all rated at 1600V. Select the model that provides sufficient margin above your actual operating current.
Q: Is a heat sink required for this rectifier diode module?
A: Yes. If your actual working current exceeds 5A, a suitable heat sink must be used. Proper thermal management is essential for reliable long-term performance and to prevent overheating of the module.
Q: Can this MDK diode module be used in solar photovoltaic (PV) systems?
A: Absolutely. The MDK 1600V anti-reverse rectifier diode module is specifically designed for photovoltaic (solar) applications, preventing reverse current from flowing back into the solar panels and protecting your PV system components.
Q: What is the difference between the nominal current and the actual operating current for this module?
A: The nominal current printed on the module is the average on-state value. For resistive loads, multiply your actual current by 2–2.5 to determine the required module rating. For inductive loads, use a multiplier of 6–7 to ensure a safe operating margin.
Q: Are custom configurations or bulk orders available?
A: Yes. Custom configurations are supported. For bulk orders, please contact our customer service team with your required quantity so we can confirm availability and lead times.
