Everyone knows that there are many types of diode modules, of which the anti-reverse diode module is one of them. It is also called a diode to prevent reverse charging, which can prevent the current from kicking back. So what are the advantages of the anti-reverse diode module? I will give you a specific introduction today.

In the photovoltaic combiner box, when choosing anti-reverse diodes, if there are requirements in terms of grade, usually modular diodes are used, which will become more convenient. So when you choose the anti-reverse diode module, what are the main aspects? It mainly depends on the thermal resistance, voltage drop and thermal cycling ability. Everyone should choose a diode module with low thermal resistance, reduced voltage, and strong thermal cycling ability. There are two types of anti-reverse diode modules on the market now, one is ordinary. Diode modules and anti-reverse diode modules for photovoltaics are mainly used for photovoltaics. The two types of diode modules are different, specifically:

The anti-reverse diode module for photovoltaics has the characteristic of voltage drop. Its normal voltage drop is 0.76-0.80 volts, while the normal voltage drop of ordinary diode modules reaches 0.90-0.95 volts. Since the voltage drop is relatively small, the efficiency of the diode module is relatively small, so the heat dissipated will be correspondingly reduced, so that the temperature rise of the combiner box is also reduced.

The thermal resistance of the anti-reverse diode module dedicated to photovoltaics is relatively small. Its larger thermal resistance junction to the module base plate is 0.5, while the larger thermal resistance junction of the ordinary diode module to the module base plate will reach 1.3, so the thermal resistance is smaller , The smaller the temperature difference between the module bottom plate and the chip, the more reliable the operation of the diode module.

It can be seen that the anti-reverse diode module has many advantages. In addition to low thermal resistance and reduced pressure, it also has the characteristics of strong thermal cycling ability. Its thermal cycle number can reach more than 10,000 times, because it will be affected by the internal The influence of process structure process.
