Product Features1. Supports three levels of high current of 40A/65A/100A to meet the application needs of different power scenarios2. No need for grounding design, only need to be connected in series on the positive electrode, reducing system complexity3. No voltage limitation, compatible with mainstream solar panels and battery packs4. Prevent backflow and reverse connection, protect the circuit from reverse current damage5. Quickly respond to reverse polarity situations within 2 μ s, with a very fast response speed6. The product has the advantages of low internal resistance, low heat generation, low loss, and high efficiencymain purpose1. Power anti reverse connection: In car, industrial, and lithium battery systems, to prevent circuit damage caused by reverse voltage2. Low loss unidirectional conduction: replaces Schottky (which cannot be used in rectifier circuits) and significantly reduces voltage drop and heat generation in high current scenarios3. Anti backflow and parallel connection of multiple power sources: achieve redundant power supply, avoid current backflow, and zero standby power consumptionProduct Parameters40A versionNumber of MOS transistors: 1Reverse voltage: ≤ 40VMinimum input voltage: ≥ 1VMaximum input voltage: unlimitedPeak current: 60AWorking current: 40AInternal resistance of MOS tube conduction: ≈ 0.9m ΩReverse shutdown response time: 2 μ sReverse leakage current: ≈ 110 μ A65A versionNumber of MOS transistors: 2 in parallelReverse voltage: ≤ 40VMinimum input voltage: ≥ 1VMaximum input voltage: unlimitedPeak current: 80AWorking current: 65AInternal resistance of MOS tube conduction: ≈ 0.45m ΩReverse shutdown response time: 2 μ sReverse leakage current: ≈ 110 μ A100A versionNumber of MOS transistors: 4 in parallelReverse voltage: ≤ 40VMinimum input voltage: ≥ 1VMaximum input voltage: unlimitedPeak current: 150AWorking current: 100AInternal resistance of MOS transistor conduction: ≈ 0.22m ΩReverse shutdown response time: 2 μ sReverse leakage current: ≈ 110 μ APrecautions1. When using, the current should not exceed the maximum working current and a 20% margin should be left2. Do not exceed the maximum reverse voltage of the module. Considering the presence of peak voltage, a 30% margin must be left3. Modules cannot be used as freewheeling diodes in AC circuits4. Pay attention to heat dissipation to avoid module temperature exceeding 110 ° C, otherwise the MOS transistor driver will fail. A heat sink can be attached to the back of the module to dissipate heat and reduce operating temperatureMust see for useWhen using, please note that although the module has no forward voltage limitation, it has a reverse voltage limitation. (Ensure that the reverse voltage is below 40V)Due to the fact that the module does not require grounding during operation, its advantages are obvious compared to modules that require grounding. It can be directly connected in series into the circuit like a diode, with a static working current of 0. However, there are also disadvantages. If your product is sensitive to the following factors, it is not suitable for this module:1. It is sensitive to fluctuations in output voltage. During module operation, there is a certain period of time when the voltage drop is above 0.3V, usually not exceeding 0.7V. This time is very short, accounting for about 2% of the entire working time. That is to say, after working for about 100S, the voltage drop will be greater than 0.3V for about 2S, but each time the voltage drop is too large, it will be within 40ms2. The working current is less than 10ma and sensitive to voltage fluctuations (unable to accept voltage fluctuations of around 0.4V, although measured at 0.3V). For anti backflow, there will be a small current passing through. That is to say, when you connect the output port to the input power supply, the input port of the module can measure the voltage, but the current that can pass through is ≈ 110 μ A. Most load devices can lower this voltage3. Not suitable for devices such as microcontrollers that operate with small currents. It cannot replace the freewheeling diode in switch mode power supplies, but it can be used for anti backflow.Packing ListIdeal diode module * 1 (style optional)
