STAC2932BW

Overview

The STAC2932BW is an N-channel RF power MOSFET manufactured by STMicroelectronics, designed for high-frequency applications up to 175 MHz. It operates with a drain-source voltage of 50 V and delivers a typical output power of 390 W at this frequency. The device features a gain of approximately 21 dB under standard test conditions. Packaged in the STAC244F air-cavity format, it supports surface mount installation. Key electrical parameters include a continuous drain current rating of 40 A and a maximum power dissipation capability suited for large signal operations.

Feature Summary

• Utilizes ST air-cavity STAC packaging technology for superior thermal management
• Features gold metallization for enhanced reliability and performance
• Designed for common source push-pull configurations
• Provides excellent thermal stability for consistent operation

Applications

• HF/VHF/UHF RF power amplification

Procurement Notes

Verify component authenticity through authorized channels. Confirm RoHS3 compliance status prior to integration. Check manufacturing date codes against project timelines. Ensure proper handling procedures are followed due to sensitivity. Validate datasheet revisions match the specific batch received.

Selection Notes

Compare output power requirements against the 390 W specification at 175 MHz. Evaluate thermal resistance characteristics for heat sink design. Consider the STAC244F package dimensions for PCB layout constraints. Assess gate drive requirements relative to the N-channel configuration. Verify compatibility with existing circuit topologies.

Part Context

This component belongs to the STAC2932 series of RF power transistors. It shares architectural similarities with models like the STAC2932FW but differs in specific packaging or testing variants. The series targets robust performance in demanding radio frequency environments.

Replacement Considerations

The STAC2932FW is a documented variant within the same product family. Verify pinout compatibility and thermal interface requirements before substitution. Confirm that the alternative meets the 390 W output power specification at the target frequency.
