The following is a systematic review of mainstream brand manufacturers from the dimensions of technical routes, market positioning, and production capacity layout:
Let's delve into the question of which is "better" between IGBT and MOSFET. It needs to be clear that there is no absolute 'better', only 'more suitable'. The choice of device depends on specific application scenarios, performance requirements, and cost considerations. The following is an original analysis of the characteristics and applicable scenarios of both:
Choosing IGBT (Insulated Gate Bipolar Transistor) and MOSFET (Metal Oxide Semiconductor Field Effect Transistor) as power switching devices is a decision that requires careful consideration of application requirements, performance characteristics, and localization factors. The following is an original and logically clear analytical framework:
Let's compare in detail the core differences between IGBT (Insulated Gate Bipolar Transistor) and MOSFET (Metal Oxide Semiconductor Field Effect Transistor), two power semiconductor devices. They are all voltage controlled switching devices, but the differences in internal structure and working principle result in significantly different performance characteristics and application scenarios.
IGBT has various packaging forms, which can be mainly divided into the following categories based on factors such as power level, application scenario, heat dissipation requirements, and integration degree. Each packaging has its unique structure and application positioning:
There are various classification methods for IGBT (Insulated Gate Bipolar Transistor), and the following analysis will be conducted from different dimensions to present its classification system in a logically clear manner:
IGBT (Insulated Gate Bipolar Transistor) is a composite power semiconductor device that combines the high input impedance of MOSFETs with the low conduction loss characteristics of bipolar transistors (BJTs).

Recommendation: Power modules equipped with SiC MOSFETs and SiC SBDs
Compared with MOSFET, SiC perfectly solves the problem of difficult simultaneous implementation of high voltage and high frequency in silicon-based materials. Based on compatibility with high voltage and medium frequency, SiC MOSFET has become the optimal solution for electric vehicles, charging stations, and photovoltaic inverters (without considering cost) due to its high efficiency and small size;
Gallium nitride (GaN) and silicon carbide (SiC) power transistors, two types of compound semiconductor devices, have emerged as solutions. These devices compete with long-life silicon power lateral diffusion metal oxide semiconductor (LDMOS) MOSFETs and super junction MOSFETs. GaN and SiC devices are similar in some aspects, but there are also significant differences.
