Discrete IGBT devices are power semiconductor products in which a single IGBT chip is integrated with a free-wheeling diode (FWD) through a packaging process to form a single, independent device; they serve as the fundamental core components of IGBT modules and intelligent power modules (IPMs).

       Common packages include D2PAK, TO-247, TO-220, and TO-247, covering applications ranging from low power to high power (such as current ratings up to 160 A). They are widely used in general-purpose variable-frequency drives, solar inverters, uninterruptible power supplies (UPS), induction heating equipment, home appliances, and switching power supplies (SMPS), among others.
