According to statistics, in 2022, the market sales volume of China's two-wheeled electric bicycles reached approximately 56.7 million units, breaking a new historical high. In the fierce competition of the entire market, Yadea and Aima are the two brands with the highest sales volumes, selling 14.01 million and 10.51 million electric vehicles respectively.

From the data and trends, it is clear that two-wheeled electric bicycles will continue to improve in the future. After all, the process of new energy determines the direction of development. Then, for the improvement of electric bicycle product quality, motor control plays a very important role.

Among them, MOSFETs are an important component in the motor control of electric bicycles. Which styles of MOSFETs are commonly used in motor control?

For the foreign FDBL86066 low-voltage MOS model, can a better replacement model be found domestically? In fact, domestically, there is already the FHL170N1F4A low-voltage MOS tube model whose parameters can often replace FDBL86066 for motor control in electric bicycles.

Firstly, the FHL170N1F4A MOS tube model is produced by a domestic MOS tube manufacturer that has been dedicated to research and development for 20 years. Its excellent manufacturing process and parameter performance can better adapt to the motor control of electric bicycles, optimizing the overall machine control efficiency.

The core of MOS tube substitution lies in parameter performance. Why is it said that the domestic FHL170N1F4A field effect transistor can better substitute the foreign FDBL86066 model parameters in the motor control of electric bicycles?

Let’s take a look at the specific product parameters of this Fei Hong FHL170N1F4A: current 172A, voltage 100V, RDS(on) = 4.0mΩ(MAX) @VGS = 10V, RDS(on) = 3.2mΩ(TYP) @VGS = 10V, maximum gate-source voltage @VGS = ±20V.

FHL170N1F4A is an N-channel enhancement mode field effect transistor. The FHL series adopts the TOLL-8L package form, which has features such as low package resistance, low parasitic inductance, small size, and low thermal resistance.

This product also has specific parameter values: Vgs(±V): 20; VGS(th): 2.0-4.0V; ID(A): 172A; BVdss(V): 100V.

Maximum pulse drain current (IDM): 480A, static on-resistance (typ): 3.2mΩ, reverse transfer capacitance: 33pF.

In the process of domestication of field effect transistors, the Fei Hong domestic model FHL170N1F4A parameters can replace the FDBL86066 model, and it has the following characteristics:

1. Industrial-grade reliability: Small package inductance, bringing excellent EMI characteristics and reliability.

2. 100% EAS test

3. 100% DVDS thermal resistance test (lower thermal resistance, bringing excellent temperature rise performance)

4. 100% Rg test

5. Low on-resistance: supports smaller impedance and larger peak current.

More suitable for industrial applications, therefore more widely used in high-power density application scenarios such as electric bicycles, electric motorcycles, electric sightseeing cars, lithium battery protection, communication power supplies, etc.; mos tube brand replacement models: FDBL86066.

The use of a 100V, 172A MOS tube requires selecting the right model. Fei Hong Semiconductor's MOS tubes have been widely applied in motor control, power circuits, smart home appliances, new energy electronics fields: such as automotive electronics, electric bikes, smart speakers, household appliances, LED lighting, chargers, computer power supplies, and other industries, providing high-quality products and supporting services to domestic electronic product manufacturers.
