BFR94AW,115

Overview

The BFR94AW,115 is a discontinued NPN wideband RF transistor manufactured by NXP USA Inc. It operates with a maximum collector-emitter voltage of 15V and a continuous collector current of 25mA. The device features a transition frequency of 5GHz and a maximum power dissipation of 300mW. DC current gain is specified at a minimum of 65 under standard test conditions. Noise performance ranges from 2dB to 3dB within the 1GHz to 2GHz frequency band. The component utilizes an SC-70 (SOT-323) surface-mount package and supports junction temperatures up to 150°C.

Feature Summary

• Wideband operation capability optimized for high-frequency signal processing
• Integrated ESD protection mechanisms for enhanced circuit reliability
• Surface-mount construction in a compact SC-70 footprint

Applications

• RF amplification stages in wireless communication systems
• Broadband signal processing circuits
• High-frequency oscillator applications

Procurement Notes

This component has been officially declared obsolete and is no longer in production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Buyers must confirm the authenticity of existing stock and review datasheet revisions carefully, as specifications may have evolved prior to discontinuation. Compliance with RoHS directives remains relevant for legacy inventory assessment.

Selection Notes

Designers requiring this specific part number must evaluate alternative components due to its end-of-life status. Selection criteria should prioritize matching the original 5GHz transition frequency and 15V breakdown voltage limits. Package compatibility with the SC-70 form factor is essential for board-level replacements. Verify that substitute devices offer comparable noise figures and thermal stability for the intended operating environment.

Part Context

The BFR94AW belongs to the BFR92/BFR94 series of NPN silicon RF transistors designed for broadband applications. This series is characterized by high linearity and low noise performance suitable for multi-standard radio front ends. The '115' suffix indicates the specific tape-and-reel packaging configuration used for automated assembly processes.

Replacement Considerations

Publicly confirmed substitutes include the Rohm Semiconductor 2SC4713KT146R and Infineon Technologies BFP181E7764HTSA1. These alternatives are listed as similar functional replacements in distributor databases.
