Additional Details:

The IRF6623TR features a trench MOSFET structure. Its DirectFET® package has a very low parasitic inductance, contributing to its excellent high-frequency performance. It typically operates with a drain-source voltage (Vds) of up to 30V and a continuous drain current (Id) that can vary depending on the specific operating conditions and heatsinking. The operating junction temperature ranges typically from -55°C to +175°C. Always refer to the manufacturer's datasheet for detailed specifications and application guidelines.
