Matters needing attention
1. The module must be used together with the ground, and the input terminals must not be reversed without reverse protection.
2. When the module operates with high current, it is necessary to pay attention to heat dissipation. It has been tested for 10A without heat dissipation measures (12V 25 ° C), but due to the small size of the module, it is still in a relatively hot state.
3. The module cannot replace the freewheeling diode in a switching power supply, but it can be used to prevent backflow at the output end.
4. When working at a low voltage of around 3V, the internal resistance of the module will be too high, so the current that can be passed will be less than the test value at 12V
5. The measured minimum voltage drop of the module is about 53mv, and it will not drop to 0 due to low current.
