H20R1203 transistor


H20R1203 is 1200V, 20A, IGBT. A reverse conducting IGBT (Insulated Gate Bipolar Transistor) with a monolithic body diode is a type of IGBT that incorporates a built-in or integrated diode within its structure. This diode, also known as a body diode or freewheeling diode, provides a low-loss path for current flow in the reverse direction when the IGBT is in the off state.

The IGBT is a power semiconductor device that combines the features of a MOSFET (voltage-controlled operation) and a bipolar transistor (low on-state voltage drop). It is commonly used in power electronics applications for high-power switching and amplification.

Reverse conducting IGBTs with monolithic body diodes are commonly used in various applications, including motor drives, power inverters, uninterruptible power supplies (UPS), and industrial power systems. They offer efficient and reliable switching performance while simplifying circuit design and reducing component count.
