K120T60 IGBT Transistor 600V, 120A 3V RGB 2835 SMD LED (Pack of 8000) This gear has 51/24 teethK120T60 is an Insulated Gate Bipolar Transistor. It is a Three terminal semiconductor switching device that can be used for fast switching with high efficiency in many types of electronic devices. These devices are mostly used in amplifiers for switching processing complex wave patterns with pulse width modulation (PWM). An IGBT is a fusion between a BJT and MOSFET. The symbol of the IGBT also represents the same, as you can see the input side
