STGB10NB37LZ

STGB10NB37LZ Description

The STGB10NB37LZ from STMicroelectronics is a high-performance N-channel IGBT (Insulated Gate Bipolar Transistor) designed for power switching applications. With a collector-emitter breakdown voltage (V_CES) of 440V and a maximum collector current (I_C) of 20A, this device is optimized for efficiency and reliability in medium-power circuits. It features a low V_CE(on) of 1.8V @ 4.5V, 10A, ensuring minimal conduction losses, and offers fast switching characteristics with turn-on/off delays of 1.3µs and 8µs, respectively. The PowerMESH™ technology enhances thermal performance, supporting a maximum power dissipation of 125W. Packaged in a D2PAK (TO-263) surface-mount format, it is suitable for automated assembly processes.

STGB10NB37LZ Features

• High Voltage & Current Handling: 440V V_CES and 20A I_C (40A pulsed) for robust performance.
• Low Switching Losses: 2.4mJ (on) and 5mJ (off) switching energy improves efficiency in high-frequency applications.
• Optimized Gate Drive: 28nC gate charge reduces drive requirements, enabling faster switching.
• Thermal Efficiency: PowerMESH™ design ensures superior heat dissipation.
