The application of welding machines in the field of industrial processing is very extensive, and their categories include DC welding machines, TIG welding machines, AC arc welding machines, CO2 shielded welding machines, butt welding machines, spot welding machines, etc. For welding machines that use a full-bridge topology structure, today we recommend an excellent IGBT single tube for application in welding machines.

If welding machine manufacturers are currently using NGTB25N120FL2WG single IGBT tubes and are looking for a domestic IGBT replacement, it is recommended to consider the FHA25T120A single tube model. It can effectively solve performance improvement and reliability issues!

Because the short tail current, excellent Vcesat saturation voltage drop, and low turn-off loss product features it possesses can make the full-bridge topology circuit of the welding machine run better!

Specifically, you can see the product parameters of this FHA25T120A from Feihong. It has a current of 25A and a voltage of 1200V, with typical values of VCEsat: 1.78V-typ VGE=15V, IC=25A, TJ =25°C; IC (Tc=100℃): 25A; BVCES: 1200V; IF(A)(Tc=25°C): 30A; IF(A)(Tc=100°C): 15A.

FHA25T120A is a trench gate stop type IGBT, and other MOS tube brand alternative models: NGTB25N120FL2WG. It is commonly used in various soft and hard switch circuits and PFC circuits such as welding machines, UPS, solar inverters, etc., suitable for switching frequencies of 1~40KHz and other applications.

The other parameter values of FHA25T120A are: gate body leakage current IGES(F/R): (VCE=0V, VGE=±30V): ±200nA, reverse transfer capacitance: 67.3pF.

In the process of replacing domestic IGBT single tubes, the Feihong domestic model FHA25T120A is selected to replace the NGTB25N120FL2WG model. It has the following characteristics:

1. High reliability

2. Possesses fast recovery diodes connected in parallel in reverse

3. Trench Field Stop Technology (short tail current, excellent Vcesat saturation voltage drop, low turn-off loss)

4. Has a positive temperature coefficient

5. Tjmax=175℃

6. Switching frequency fsw=40KHz

The development of welding machines has evolved from severe losses in hard-switching to the progress of soft-switching. In the future, development and usage will undoubtedly require more high-quality electronic components. Therefore, choosing a reliable and continuously improving domestic IGBT manufacturer is very important. Currently, the IGBT single tube model FHA25T120A is a good choice for replacement models with parameters.

For the replacement of 1200V, 25A IGBT single tubes, choosing the right model is crucial. The IGBT single tubes from Feihong Semiconductor have been widely applied in motor control, power supply circuits, smart home appliances, new energy electronics sectors: such as automotive electronics, household appliances, LED lighting, electric vehicles, smart speakers, chargers, computer power supplies, and other industries, providing high-quality products and supporting services for domestic electronic product manufacturers.
