For the inverter and PWM (pulse width modulation) control circuit in the TIG welding machine, if it is necessary to optimize the circuit for high precision and fast response functions, a high voltage, stable current IGBT single tube is required.

If the TIG welding machine manufacturer is currently using the NGTB25N120FL2WG IGBT single tube and is looking for a domestic IGBT replacement, it is recommended to consider the FHA25T120A single tube model. It can effectively improve product performance and reliability!

Because its short tail current, excellent Vcesat saturation voltage drop, and low turn-off loss product features can make the TIG welding machine operate better!

Specifically, you can check the product parameters of this FHA25T120A from Feihong. It has a current and voltage of 25A and 1200V, with a typical VCEsat value: 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.

The FHA25T120A is a trench gate-stop type IGBT, with other MOSFET brand alternative models: NGTB25N120FL2WG. It is commonly used in various soft and hard switching and PFC circuits such as TIG welding machines, UPS, solar inverters, etc., applicable to switching frequencies of 1~40KHz, etc.

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 domestic IGBT single tube substitution, the domestic model FHA25T120A from Feihong has the following characteristics:

1. High reliability

2. Possessing a fast recovery diode in parallel

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

4. Positive temperature coefficient

5. Tjmax=175℃

6. Switching frequency fsw=40KHz

Modern TIG welding machines typically use IGBTs to achieve more stable arcs, and future development and use will increasingly require high-quality electronic components. Therefore, choosing a reliable and continuously improving domestic IGBT manufacturer is very important. Currently, the IGBT single tube with the FHA25T120A model parameters is a good choice for replacement.

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