Procurement Notes

Verify the exact datasheet revision and specific electrical characteristics against the manufacturer's official documentation before integration. Confirm that the TO-247AD package dimensions match the target PCB layout requirements. Ensure thermal management solutions are adequate for the intended operating conditions.

Selection Notes

Select this component when a 900V N-channel RF MOSFET is required in a TO-247AD form factor. Evaluate thermal resistance and gate drive requirements against system specifications. Compare performance metrics with alternative devices if higher current or lower on-resistance is needed.

Part Context

The ARF444 belongs to Microsemi's portfolio of RF power transistors, now part of Microchip Technology Inc. following acquisition. These components target aerospace, defense, and communications sectors, emphasizing reliability and high-performance analog and mixed-signal semiconductor solutions for critical applications.

Replacement Considerations

Consult Microchip's official replacement guide for comparable parts with modified specifications. Verify pinout compatibility and thermal interface requirements when substituting.
