The MOSFET is a very important component in the solar charge controller, directly affecting the accuracy of charging control, system efficiency and reliability, and ultimately impacting the performance and lifespan of the entire solar system. Therefore, how to choose a high-quality and reliable MOSFET to make the solar charge controller more efficient and reliable?

In response to this requirement, the engineers at Feihong Semiconductor suggest using the 100N8F6A to replace the STP110N8F6 model field-effect transistor.

Why choose 100N8F6A to replace the STP110N8F6 field-effect transistor? This is because this MOSFET with TO-220 package is widely used in various solar controllers and has been recognized by many manufacturers. Moreover, its voltage of 85V and current of 120A are also very suitable for use in solar controllers.

Let's review the specific product parameters:

It has a current of 120A and a voltage of 85V, RDS(on) = 6.5mΩ(MAX) @VGS = 10 V, RDS(on) =5.3mΩ(TYP) @VGS = 10 V, maximum gate-source voltage @VGS =±20 V.

100N8F6A is an N-channel enhancement mode field effect transistor, with a TO-220 package size suitable for circuits.

This product has specific parameter values: Vgs (±V): 20; VGS (th): 2.0-4.0V; ID (A): 120A; BVdss (V): 85V.

Maximum pulse drain current (IDM): 320 (A), reverse transfer capacitance: 18pF.

正是因为 the above parameters of this MOSFET, it allows for fast switching speed and low on-resistance, thus reducing energy loss and improving the efficiency of the solar charge controller. Therefore, it requires a strong supply chain manufacturer of electronic components to ensure this. It is recommended to understand the domestic model from Feihong: the 100N8F6A model parameters can be used to replace the STP110N8F6 model for application.

Replacing the 120A, 85V MOSFET, selecting the right model parameters will improve the product strength of the enterprise. Feihong has obtained 15 utility patents and inventions, and cooperates with Sun Yat-sen University and the Chinese Academy of Sciences to develop GaN devices. Feihong products have been widely used in solar controllers, various DC/DC power supplies, energy storage power supplies, DC-AC inverters, AC-DC switch power supplies, garden tools, and BLDC motor drives, helping partners solve domestic quality products that meet national conditions and international standards.
