Solar Anti-Backflow Perfect Diode Module 15A 2-Pack
Solar Anti-Backflow Perfect Diode Module 15A 2-Pack
Solar Anti-Backflow Perfect Diode Power Supply Module – 15A (2-Pack)
Upgrade your solar panel system or battery charging setup with this high-efficiency 15A Perfect Anti-Backflow Diode Module. Engineered with an ultra-low 8 milliohm internal resistance and dual parallel MOSFET design, it dramatically reduces voltage drop and heat generation compared to conventional diodes — delivering better efficiency and longer component life.
Made in Mainland China.
Why Choose This Anti-Backflow Diode Module?
A standard diode can have a voltage drop of 0.2V–0.7V. At 10A, that means up to 2W of wasted energy converted entirely to heat — enough to degrade or destroy a conventional diode over time. This perfect anti-backflow diode module uses an advanced low-resistance design to keep heat minimal and efficiency high, making it an ideal drop-in upgrade for any DC power circuit.
Key Features
- Ultra-Low Internal Resistance: 8 milliohm per channel, two channels in parallel — virtually eliminates voltage drop losses
- Wide Voltage Range: Works across DC 5V–60V systems
- High Current Capacity: Rated 15A continuous (18A peak); run multiple units in parallel for higher current applications
- Minimal Standby Draw: Only 0.2mA static working current at 12V
- Wide Operating Temperature: -40°C to +85°C for reliable year-round outdoor use
- Compact & Durable: Green PCB with plastic housing — lightweight and easy to integrate

Frequently Asked Questions
Q: What is a perfect anti-backflow diode module and how does it differ from a standard diode?
A: A perfect anti-backflow (ideal) diode module uses low-resistance MOSFETs controlled by a driver circuit to replicate diode behavior with far less energy loss. A conventional diode can drop 0.2V–0.7V across it (wasting energy as heat), while this module's 8 milliohm internal resistance keeps voltage drop near zero, greatly improving system efficiency and reducing heat buildup.
Q: Can I use multiple modules together for higher current applications?
A: Yes. These modules are designed to be connected in parallel to increase total working current capacity beyond the 15A single-module rating. This makes them flexible for a wide range of solar panel sizes and battery bank configurations.
Q: What voltage systems is this module compatible with?
A: This module supports DC 5V to 60V systems, making it compatible with most 12V, 24V, and 48V solar and battery charging setups commonly used in residential and off-grid applications.
Q: Do I need a heatsink for continuous operation?
A: For continuous operation above 10A, a heatsink is recommended to maintain optimal thermal performance and longevity. Below 10A continuous, the module can operate without a heatsink within its rated temperature range of -40°C to +85°C.
