The core characteristic of the electric welder is the high-voltage IGBT. How should an electric welder select a high-voltage IGBT factory to ensure it uses a suitable high-voltage IGBT product?

On May 9, 2023, Feihong Semiconductor's high-voltage IGBT factory received an inquiry from Mr. Xun from Shaanxi Province.

According to the description, the 75A and 650V parameters are the focus points of Mr. Xun, the technical staff of the electric welder manufacturer seeking domestic high-voltage IGBT replacement factories. His intention was to seek out a high-quality high-voltage IGBT factory.

Subsequently, Mr. Xun inquired about Feihong's high-voltage IGBT factory providing a domestic high-voltage IGBT solution suitable for electric welders, capable of replacing the FGH75N65SHDT IGBT model.

After understanding the situation, Feihong Semiconductor's high-voltage IGBT factory immediately dispatched a team to address Mr. Xun's electric welder circuit diagram requirements.

They arranged a domestically produced high-voltage IGBT that was just right and suitable for electric welders. Based on Mr. Xun's actual status in Shaanxi Province, it was recommended to use the FHA75T65A IGBT instead of the FGH75N65SHDT IGBT model for the electric welder circuit diagram.

Why is the FHA75T65A IGBT model chosen?

Because the FHA75T65A IGBT model not only has a positive temperature coefficient characteristic but also possesses excellent Vcesat saturation voltage drop and RoHS products.

Moreover, the FHA75T65A model has a current and voltage parameter feature of 75A and 650V. This high-voltage IGBT is particularly suitable for use in electric welders.

Importantly, high-voltage IGBTs control steadily and have good quality in electric welders!

Of course, as a circuit diagram technician for electric welders, one must understand the detailed parameters of this domestic high-voltage IGBT, FHA75T65A:

The FHA75T65A is a channel N trench gate-off type 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.

Ultimately, Shaanxi Feihong Semiconductor's high-voltage IGBT factory successfully addressed Mr. Xun's high-voltage IGBT supply needs.

After testing, Mr. Xun explained the reason for choosing Feihong Semiconductor:

He intended to enhance the power switch capability of the electric welder. Feihong Semiconductor solved Mr. Xun's requirements, so he chose the FHA75T65A IGBT model.

Feihong Semiconductor provides high-voltage IGBT OEM services, solving the high-voltage IGBT needs for electric welders, and the quotations for domestic high-voltage IGBTs are reasonable.

Mr. Xun mentioned that Feihong Semiconductor approached the customization of high-voltage IGBTs with a warm and determined attitude. He hopes they continue to persevere, strive for success, and provide high-quality FHA75T65A model parameters.

The domestic FHA75T65A model can be used for electric welders.
