DF400R12KE3HOSA1 is an insulated gate bipolar transistor (IGBT) module developed by Infineon. It possesses an industry-standard 3-level inverse diode pre-mount scheme and a high integration level, among other features.

IGBTs are hybrid components that combine the features of both MOSFETs and bipolar transistors, and their most typical application is to boost power supply voltage. They are preferred over IGBTs with lower voltage ratings because of their higher efficiency and power handling capabilities. Furthermore, their gate resistance rating is much lower than that of bipolar transistors, thus reducing total gate charge losses and making them suitable for applications requiring low-temperature operation.

DF400R12KE3HOSA1 is an IGBT module with a 3-level inverse diode pre-mount scheme. This design offers higher efficiency than 2-level designs and is suitable for applications such as AC-DC power conversion and motor drives. Furthermore, the high integration level of the module reduces external component count and improves efficiency by using single-drive center tap control.

The working principle of DF400R12KE3HOSA1 is based on the IGBT basic concept, which combines MOSFET and bipolar transistor elements. The module combines a gate-emitter voltage, a collector-emitter current, and a base-collector voltage. The gate-emitter voltage acts as an on/off switch for the IGBT, allowing for the control of the collector voltage. By applying a controlled gate-emitter voltage, the collector-emitter current can be adjusted. This in turn leads to an adjustment of the base-collector voltage, thus allowing for precise control of the IGBT.

The DF400R12KE3HOSA1 is a suitable component for a variety of products with moderate to high power ratings. Its suits a wide range of applications, including AC-DC power conversion, variable speed motor drives, UPS systems, welding equipment and power modules.

Its integration level and pre-mount scheme enable it to provide high efficiency and performance. Moreover, its lower gate resistance reduces total gate charge losses and the low temperature operation makes it suitable for low temperature applications. Overall, the DF400R12KE3HOSA1 is an ideal choice for moderate to high power applications.
