QM75DY-HB Circuit Diagram

QM75DY-HB Circuit Diagram

The QM75DY-HB circuit diagram represents a dual IGBT (Insulated Gate Bipolar Transistor) module designed for high-power switching applications, such as motor drives, power inverters, and industrial power supplies. The schematic illustrates two IGBT switches arranged in a half-bridge configuration, which allows efficient and high-speed switching of large currents.

Each IGBT has a freewheeling diode connected in parallel to handle reverse current and protect against voltage spikes caused by inductive loads. The gate drive circuitry, consisting of resistors and diodes, ensures controlled switching behavior, minimizing power losses and enhancing reliability. The circuit includes multiple connection points (B1, B2, E1, E2, and C1), which define the electrical paths for current flow between the IGBTs and their respective load connections.

The C2E1 node in the middle suggests a shared connection between the two IGBTs, forming a bridge topology that is commonly used in DC-AC inverters and motor control applications. The additional diodes and resistors near the gates indicate built-in protection features, such as voltage clamping and soft switching, to enhance the lifespan and efficiency of the module.

Overall, this IGBT module provides high efficiency, fast switching speed, and thermal stability, making it an ideal choice for industrial power electronics and motor drive systems.

QM75DY-HB Outline Drawing

The QM75DY-HB packaging dimension diagram provides a detailed mechanical layout of the IGBT module, specifying its physical size, terminal positions, and mounting features. The module has an overall width of 94mm, a height of 31mm, and a depth of 34mm, making it compact yet suitable for high-power applications.

The top view illustrates four main connection terminals labeled C2E1, E2, C1, and E1, each spaced 20mm apart, ensuring convenient electrical connections. The terminals are secured with M5 screws, providing a firm and reliable electrical contact. The mounting holes, with a diameter of 6.5mm, are positioned 80mm apart, allowing stable fixation on a heat sink or circuit board.

From the side view, the module's height distribution is clearly defined. The tab terminal (#110, t=0.5mm), extending 7mm from the casing, is used for auxiliary connections such as gate drive signals. The base section, designed for heat dissipation, ensures efficient thermal management when mounted onto a cooling surface.

This compact and well-structured design makes the QM75DY-HB ideal for applications requiring efficient heat dissipation, secure mounting, and high-power handling.
