The main concern of the sewing machine inverter is the high-power IGBT, which can directly affect its efficiency. So, which part of the problem should be focused on when selecting a high-power IGBT to get a product suitable for the sewing machine inverter circuit?

On February 20, 2023, the high-power IGBT factory of Feihong Semiconductor received an inquiry from Mr. Bortala Xinjiang.

According to the description: The previous IGBT model used by the sewing machine inverter manufacturer was FGH40N60SFD from Fairchild. Given the current situation and conditions, it is hoped that a domestic high-power IGBT factory can provide the FHA40T65A high-power IGBT model to replace the FGH40N60SFD IGBT model from Fairchild for use in the sewing machine inverter.

For this reason, Mr. Ding consulted with the high-power IGBT factory of Feihong Semiconductor, hoping they could provide a domestic high-power IGBT solution suitable for the sewing machine inverter and capable of replacing the FGH40N60SFD IGBT model from Fairchild.

After understanding the situation, the high-power IGBT factory of Feihong Semiconductor immediately allocated a team to focus on Mr. Ding's requirements for the sewing machine inverter circuit.

They worked on finding an appropriate and suitable domestic high-power IGBT for the sewing machine inverter. Based on Mr. Bortala Xinjiang's actual circumstances, it was suggested to use the FHA40T65A to replace the FGH40N60SFD IGBT model from Fairchild in the sewing machine inverter circuit.

Why is the FHA40T65A IGBT model?

Because the FHA40T65A IGBT model not only has the characteristic of low gate charge but also features excellent Vcesat saturation voltage drop and has a positive temperature coefficient, among other advantages.

Moreover, the FHA40T65A model has current and voltage parameters of 40A and 600V, respectively. These characteristics make this high-power IGBT very suitable for use in sewing machine inverters.

Most importantly, a mature and stable high-power IGBT with excellent quality!

Of course, as a technician for the sewing machine inverter circuit, it is necessary to inquire about the detailed parameters of this domestic high-power IGBT, FHA40T65A:

FHA40T65A is a channel N-type trench-gate cutoff type with a current of 40A and a voltage of 600V, typical VCEsat value: 1.51V, <1.85V, ID (Tc=100℃): 40A; BVCES: 600V; IF(A)(Tc=25℃): 40A; IF(A)(Tc=100℃): 20A.

Ultimately, the high-power IGBT factory of Xinjiang Bortala Feihong Semiconductor successfully executed Mr. Ding's idea for high-power IGBT supply.

After testing, Mr. Ding explained why he chose Feihong Semiconductor:

Mr. Ding carefully analyzed and selected Feihong Semiconductor because the FHA40T65A model is suitable for use in sewing machine inverters.

Feihong Semiconductor provides the service of direct sales from a high-power IGBT manufacturer with stock available, solving the need for high-power IGBTs in sewing machine inverters. Moreover, the quotations for domestic high-power IGBTs are reasonable.

Mr. Ding expressed that Feihong Semiconductor has shown meticulous care and sincerity in customizing high-power IGBT services. He hopes they will continue to strive and provide excellent parameters for the FHA40T65A model.

The sewing machine inverter manufacturers choose the high-power IGBT factory of Feihong Semiconductor to provide the most authentic component supply assurance for electronic manufacturers such as inverter power supplies and portable emergency energy storage power supplies.
