IRFB52N15D
The IRFB52N15D is a 150V N-channel MOSFET that uses HEXFET structure to support efficient switching in industrial and commercial power circuits. It has an on-resistance of 32mΩ and a continuous drain current rating of 51A, allowing stable operation in DC-DC converters, inverters, motor drives, and power supply systems where low conduction loss is required. The TO-220AB package supports standard heatsinking for effective thermal control.
Its switching behavior is supported by a total gate charge of about 60nC at 10V, enabling operation in medium- to high-frequency designs with manageable gate drive demands. The device includes avalanche handling capability and a wide safe operating area, contributing to consistent performance during voltage spikes and transient conditions found in automation, control, and energy systems.
The IRFB52N15D is suitable for power management equipment, renewable energy inverters, battery chargers, and industrial electronics where a durable N-channel MOSFET is needed. For more detailed electrical limits, thermal ratings, and characteristic curves, please refer to the official Infineon datasheet.
