In industrial applications, by precisely controlling a single IGBT chip, the inverter can achieve stepless adjustment of the fan speed, meet different ventilation volume requirements, and optimize the energy utilization efficiency of the system.

Therefore, the single IGBT chip is the most critical power switch element in the fan inverter. Commonly used single IGBT chips in the market for fan inverters include Fairchild's FGH40N60SFD. But are there any interchangeable single IGBT chips?

Why consider replacing the IGBT chip? It's mainly because domestic IGBTs have gradually matured and can perfectly replace foreign IGBT products. Therefore, to ensure product stability and safety, using domestic IGBTs has become increasingly urgent.

For this issue, Feihong Semiconductor tells you that in addition to the commonly used parameter model FGH40N60SFD, you can also choose the model FHA40T65A.

Why is this particular IGBT product? Because FHA40T65A has a fast recovery diode connected in reverse parallel, possesses high reliability, Trench Field Stop Ⅱ technology (very short tail current, excellent Vcesat saturation voltage drop, low turn-off loss), and has a positive temperature coefficient.

From the above characteristics, it is known that the parameters of this FHA40T65A model IGBT chip with 40A, 650V current and voltage can be directly used in the circuit of the fan inverter.

Of course, in application, our inverter R&D engineers must understand the detailed parameters of this excellent domestic FHA40T65A IGBT single chip: it has 40A, 650V, typical VCEsat value: 1.51V, <1.85V; IC (Tc=100℃): 40A; Bvces: 650V; IF (Tc=25℃): 40A; IF (Tc=100℃): 20A.

FHA40T65A is an N-channel trench gate IGBT, using Trench Field stop Ⅱ technology and optimized processes to achieve extremely low VCEsat saturation voltage drop, and make good trade-offs between conduction loss and turn-off loss (Eoff).

Outstanding on-state voltage drop and very short tail current provide strong assistance for customers in optimizing system efficiency. Additionally, FHA40T65A has excellent short-circuit characteristics, providing sufficient margin for motor drive circuits when handling emergencies.

Currently, the FHA40T65A model IGBT single chip is widely applicable to various products such as fan inverters, UPS, inverters, welding machines, etc. It can replace other brand models: Fairchild's FGH40N60SFD.

The package form of the FHA40T65A is TO-3PN. The parameters of this product are: Vcesat-typ (@Ic=40A): 1.51V; IC: 40A; Bvces: 650V, Vge: ±30V;.

In addition to changing the frequency, the IGBT single chip can also adjust the modulation method of the IGBT to change the effective value of the output voltage, thereby controlling the torque output of the motor, further enhancing the advantages of the fan inverter. For replacing the FGH40N60SFD parameter model IGBT single chip, it is recommended to use the FHA40T65A parameter model.

Selecting the right model for 650V, 40A IGBT replacement is crucial. Feihong Semiconductor's FHA40T65A model IGBT is not only widely used in fan inverters but also applicable to photovoltaic inverters, UPS, welding machines, white goods, and other terminal application scenarios.
