10A 1000V blocking diodes,axial rectifier diode.
Diodes placed in series with cells or modules can perform another function that of blocking reverses leakage current backwards through the modules. There are two situations where blocking diodes can help prevent the phenomenon.
• Blocking reverse flow of current from the battery through the module at night.
In battery charging systems, the module potential drops to zero at night, and the battery could discharge all night backwards through the module. This would not be harmful to the module, but would result in loss of precious energy from the battery bank. Diodes placed in the circuit between the module and the battery can block any nighttime leakage flow.
• Blocking reverse flow down damaged modules from parallel modules during the day.
Blocking diodes placed at the head of separate series wired strings in high voltage systems can perform yet another function during daylight conditions. If one string be comes severely shaded, or if there is a short circuit in one of the modules, the blocking diode prevents the other strings from loosing current backwards down the shaded or damaged string. The shaded or damaged string is “isolated” from the others, and more current is sent on to the load. In this configuration, the blocking diodes are sometimes called “isolation diodes”.
If you do not properly and effectively install a blocking diode into your renewable energy system (whether that renewable energy system is solar, water or wind), your batteries will never work efficiently. Because of this, it is important to make sure that you properly and correctly install your blocking diode. Also, a blocking diode does not protect against over currents. To protect against over currents, fuses or breakers should be installed.
1.High surge current capability
2.Low leakage and forward voltage drop
