Introduction to IGBT Parameters: Understanding the Significance of 450A

One of the key parameters used to characterize IGBTs is the current rating, typically denoted by “A” followed by a numerical value. In this context, the parameter “450A” signifies that the IGBT is capable of carrying a continuous collector current of 450 Amperes.
