ARF445

Overview

The ARF445 is an RF power MOSFET manufactured by Microsemi Corporation, designed for high-voltage and high-frequency applications. It features a maximum drain-source voltage of 900V and is housed in a TO-247 package. The component is part of the ARF444/ARF445 symmetric pair, intended for push-pull configurations in RF power amplifiers.

Feature Summary

Designed for high-voltage RF power amplifier environments
Symmetric pair configuration with ARF444 for push-pull operation
Suitable for scientific, commercial, medical, and industrial RF applications

Applications

Scientific RF power amplifiers
Commercial RF power amplifiers
Medical RF power amplifiers
Industrial RF power amplifiers

Procurement Notes

Verify the manufacturer source carefully as the ARF445 is a specialized RF component. Confirm the package type is TO-247 and that it is sourced as part of the symmetric pair with ARF444 if push-pull functionality is required. Check for authenticity due to potential availability issues.

Selection Notes

Select the ARF445 when a high-voltage (900V) RF MOSFET is needed for power amplification. Ensure compatibility with the ARF444 for balanced push-pull designs. Consider thermal management requirements associated with the TO-247 package in high-power scenarios.

Part Context

The ARF445 belongs to Microsemi's lineup of RF power transistors. It is specifically engineered alongside the ARF444 to form a matched pair, facilitating efficient design of symmetrical RF circuits. This series targets demanding applications requiring robust high-frequency performance.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Microsemi or authorized distributors for direct replacements or updated equivalents.
