How to identify IGBT insulated gate bipolar transistors? 2

4. Pin connection: The pin connection of IGBT transistors is also crucial for identification. Usually, the collector pin is the largest pin, the gate pin is the middle pin, and the emitter pin is the smallest pin. In addition, according to the pin layout diagram provided in the manual, the function of the pins can be further confirmed.

5. Package type: The package type of IGBT transistors is also an important factor in identification. Different packaging types are suitable for different application scenarios. Common packaging types include TO-220, TO-247, SOT-223, etc.

6. Brand logo: IGBT transistors usually have a brand logo, which can be confirmed by checking brand information to identify the brand of the device. Some common IGBT transistor brands include Infineon, Fairchild, STMicroelectronics, etc.

In summary, identifying IGBT insulated gate bipolar transistors requires reference to multiple factors such as device appearance characteristics, model queries, electrical parameters, pin connections, packaging types, and brand identification. By integrating the above information, the model and specifications of IGBT transistors can be accurately identified.
