What aspects should be considered when selecting an IGBT tube for a sewing machine inverter that requires parameters of 75A and 650V?

On October 4, 2017, the IGBT tube factory of Feihong Semiconductor received an inquiry from Mr. Ba from Hengyang, Hunan Province.

According to the description, Technician Ba was looking for a domestic IGBT tube to replace Fairchild's FGH75N65SHDT model IGBT. He hoped to find a 75A, 650V IGBT with excellent quality.

Therefore, he consulted the IGBT tube factory of Feihong Semiconductor hoping they could provide a domestic IGBT tube solution suitable for the sewing machine inverter and capable of replacing Fairchild's FGH75N65SHDT model IGBT.

After understanding the situation, the IGBT tube factory of Feihong Semiconductor immediately dispatched a team based on the circuit diagram requirements of Mr. Ba's sewing machine inverter.

They adjusted the appropriate and suitable domestic IGBT tube for the sewing machine inverter. Considering the environment of Mr. Ba from Hengyang, Hunan Province, it was recommended to use the FHA75T65A domestic IGBT to replace Fairchild's FGH75N65SHDT model IGBT in the sewing machine inverter circuit diagram.

Why is the FHA75T65A model IGBT?

Because the FHA75T65A model IGBT not only has high reliability characteristics but also has advantages such as low VCEsat and positive temperature coefficient.

In addition, the FHA75T65A model has current and voltage parameter features of 75A and 650V, which makes this type of IGBT tube particularly suitable for use in sewing machine inverters.

Importantly, the FHA75T65A model IGBT is controlled stably in the sewing machine inverter.

Of course, as a circuit diagram technician for the sewing machine inverter, you need to know the detailed parameters of this domestic FHA75T65A IGBT tube:

The FHA75T65A is a field N-channel trench gate turn-off IGBT with 75A and 650V, typical VCEsat value: 1.75V-typ, <2.0V, ID (Tc=100℃): 75A; BVCES: 650V; IF(A)(Tc=25℃): 150A; IF(A)(Tc=100℃): 75A.

Finally, the IGBT tube supply plan of the Hengyang Feihong Semiconductor IGBT tube factory in Hunan Province successfully met Mr. Ba's requirements.

After the trial sample, Mr. Ba explained the reasons for choosing Feihong Semiconductor:

Through the introduction of a helper, he learned that Feihong Semiconductor is a reliable and powerful IGBT tube factory in Hengyang, Hunan Province, so he chose the FHA75T65A model IGBT for the sewing machine inverter.

Feihong Semiconductor provides a service of selling IGBT tubes directly from the manufacturer with stock available, solving the IGBT tube needs of the sewing machine inverter. Moreover, the price of domestic IGBT tubes is reasonable.

Mr. Ba said that Feihong Semiconductor has thoughtfully and readily provided customized IGBT tube services. He hopes that Feihong Semiconductor will continue to improve and produce quality FHA75T65A model IGBT tubes.

The domestic FHA75T65A model can commonly be used in sewing machine inverters. The IGBT tube factory of Feihong Semiconductor provides reliable component supply guarantees for frequency conversion inverters, outdoor energy storage power supplies, and other electronic manufacturers.
