In general, AC arc welders need to work on AC power. Common circuit designs include filter circuits, rectifier circuits, and inverter circuits. To make the inverter circuit run well, it is necessary to choose a good IGBT.

Besides the NGTB25N120FL2WG model on the market, what other domestic high-quality IGBT models can be used for the inverter circuit of AC arc welders? In fact, the FHA25T120A IGBT single tube from Feihong Semiconductor can already replace it relatively well, with stable production capacity and reliable quality.

Because the FHA25T120A IGBT single tube not only has the high voltage required by AC arc welders, but also has the following characteristics:

1. High reliability

2. It has a fast recovery diode connected in parallel in reverse

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

4. It has a positive temperature coefficient

5. Tjmax=175℃

6. Switching frequency fsw=40KHz

IGBT single tubes need to be safe, stable, and reliable, not only in performance but also in production capacity and supply. Feihong Semiconductor's production line is stable, with good supply quality. The key point is that the parameters of this 25A, 1200V current and voltage FHA25T120A IGBT single tube model are very suitable for use in AC arc welders.

Electronic R&D engineers who have used this IGBT from Feihong know the detailed parameters of this high-quality FHA25T120A domestic IGBT single tube: it has a current and voltage of 25A and 1200V, typical VCEsat value: 1.78V-typ VGE=15V, IC=25A, TJ =25°C; IC (Tc=100℃): 25A; BVCES: 1200V; IF(A)(Tc=25℃): 30A; IF(A)(Tc=100℃): 15A.

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

FHA25T120A is a field trench gate stop-type IGBT, and the alternative model of other MOS tube brands is NGTB25N120FL2WG. It is commonly used in various soft and hard switch and PFC circuits such as AC arc welders and UPS, applicable to switching frequencies of 1~40KHz and other scenarios.

When choosing AC arc welders, not only high cost performance needs to be considered, but also product quality and production capacity. For domestic IGBT replacement products, it is recommended to select the high-quality FHA25T120A IGBT single tube to replace the NGTB25N120FL2WG parameter model for AC arc welder circuits in UPS, so as to gain an advantage in the buyer's market!

For the replacement of 1200V, 25A IGBTs, selecting the right model is very important.
