Servo drives have extensive applications in the industrial field and are very common in fields such as injection molding machines, textile machinery, packaging machinery, CNC machine tools, etc. How should manufacturers of servo drives improve their product quality?

Generally speaking, improving the quality of servo drives requires continuous improvement in many aspects such as component selection, manufacturing process, algorithm optimization, performance testing, human-computer interaction, etc. Today, Feihong Semiconductor will share from the aspect of component selection on how to choose a high-quality domestic IGBT model to replace the Fairchild FGH40N60SFD single tube.

Currently, the domestic FHA40T65A single tube can completely replace the parameters of the FGH40N60SFD model. Next, let's introduce the detailed parameters of FHA40T65A and why it is used for replacement and application in the circuit of servo drives.

Because FHA40T65A has high reliability and features fast recovery diodes in parallel reverse direction, Trench Field Stop Ⅱ technology (short tail current, excellent Vcesat saturation voltage drop, low turn-off loss), and positive temperature coefficient characteristics.

From the above characteristics, it can be known that this 40A, 650V current and voltage FHA40T65A model IGBT parameter is very suitable for use in servo drives.

Of course, in practical applications, our servo drive R&D engineers must understand the detailed parameters of this high-quality domestic FHA40T65A IGBT single tube: it has a typical value of VCEsat @Ic=40A: 1.51V, <1.85V; IC (Tc=100℃): 40A; Bvces: 650V; IF (Tc=25℃): 40A; IF (Tc=100℃): 20A.

FHA40T65A is an N-channel trench gate turn-off IGBT, using Trench Field stop Ⅱ technology and optimized processes to achieve extremely low VCEsat saturation voltage drop, and make a good balance between conduction loss and turn-off loss (Eoff).

Now the FHA40T65A model IGBT single tube has been widely used in various hard-switching applications such as servo drives, outdoor energy storage power supplies, welding machines, photovoltaic inverters, high-frequency vehicle AC220V sine wave inverters, frequency converters, and industrial sewing machines. It can replace other brand models: Fairchild FGH40N60SFD.

The package form of FHA40T65A is TO-3PN. The product parameters are: Vcesat-typ (@Ic=40A): 1.51V; IC: 40A; Bvces: 650V, Vge: ±30V;.

As an important part of motor control, when selecting a good IGBT for replacement in servo drives, in addition to choosing the FGH40N60SFD model, the domestic model FHA40T65A parameters provided by Feihong Semiconductor can also be used as substitutes.
