SD2933-03W

Overview

The SD2933-03W is an N-channel RF power MOSFET transistor manufactured by STMicroelectronics. It utilizes silicon technology and is housed in a bulk package. The device is designed for HF, VHF, and UHF applications, delivering a minimum output power of 300 W with a gain of 15 dB at a frequency of 175 MHz. It operates within the standard semiconductor temperature range and complies with RoHS directives.

Feature Summary

• Gold metalization for enhanced thermal stability
• Common source configuration design
• Thermally enhanced packaging to reduce junction temperatures

Applications

• Industrial, Scientific, and Medical (ISM) equipment
• High-frequency radio frequency amplification circuits
• VHF/UHF transmitter stages

Procurement Notes

Verify the specific suffix -03W against the official datasheet to confirm the 175 MHz operational frequency and 15 dB gain characteristics. Ensure the bulk packaging format aligns with assembly requirements. Confirm RoHS compliance status through the manufacturer's latest documentation before integration.

Selection Notes

Select this component for designs requiring high power output at UHF frequencies. Compare the 175 MHz gain specification against system bandwidth needs. Evaluate the thermal management capabilities of the package relative to the 300 W power dissipation requirements in the target application environment.

Part Context

This part belongs to the SD2933 series of RF power transistors. It shares the gold metalized construction and ruggedness features with other members like the SD2933W, but differs in its optimized frequency response for higher UHF operations compared to lower frequency variants in the same family.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Consider the SD2933W for similar power levels if the operating frequency can be reduced to 30 MHz. Verify pin compatibility and thermal resistance parameters when evaluating alternative RF MOSFETs from the same manufacturer.
