Facing the rapid development of the new era and the swift improvement in fast charging technology, the application range of switch-mode power supplies has become more extensive. Reducing the power consumption of low-voltage high-current systems has become a challenge for electrical engineers. The effective use of MOSFETs to improve power efficiency and replace traditional rectifier diode technologies are key topics.

For the synchronous rectification problem in switch-mode power supplies, choosing a high-quality domestic MOSFET that can replace the FDBL86066 model parameters is one of the core priorities.

In the power supply industry, what are the domestic high-quality MOSFETs available for switch-mode power supplies? Besides the market's FDBL86066 parameter models, we choose the FHL170N1F4A field-effect transistor from Feihong Semiconductor.

Why? Because the FHL170N1F4A field-effect transistor has the following features:

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

2. 100% DVDS thermal resistance test (lower thermal resistance, resulting in superior temperature rise performance).

3. 100% EAS test.

4. 100% Rg test.

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

From the above description, it is clear that this industrial-grade FHL170N1F4A field-effect transistor with 172A, 100V current and voltage is very suitable for use in the synchronous rectification circuit of switch-mode power supplies.

Of course, in the application of synchronous rectification, our electrical engineers must understand the detailed parameters of this high-quality FHL170N1F4A domestic field-effect transistor: it has a current and voltage of 172A and 100V respectively, RDS(on) = 4.0mΩ(MAX) @VGS = 10V, RDS(on) = 3.2mΩ(TYP) @VGS = 10V, and the maximum gate-source voltage @VGS = ±20V.

The FHL170N1F4A is an N-channel enhancement-mode field-effect transistor. The FHL series uses the TOLL-8L package shape, and its packaged products have features such as low internal 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): 480(A), static on-resistance (typ): 3.2mΩ, reverse transfer capacitance: 33pF.

The development of the times is rapid. How to gain competitive advantages in the fiercely competitive switch-mode power supply market? The core lies in seeking high-quality FHL170N1F4A field-effect transistors to replace FDBL86066 parameter models for use in switch-mode power supply circuits.
