BFP740FH6327XTSA1

Overview

The BFP740FH6327XTSA1 is a wideband NPN RF heterojunction bipolar transistor (HBT) manufactured by Infineon Technologies using Silicon-Germanium-Carbon (SiGe:C) technology. It operates with a maximum collector-emitter voltage of 4.0 V and a total power dissipation of 160 mW. The device features a transition frequency (fT) of 45 GHz at 25 mA. Key AC characteristics include a minimum noise figure of 0.4 dB at 450 MHz and a maximum power gain of 32 dB at the same frequency. It is housed in a TSFP-4-1 surface-mount package.

Feature Summary

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the received parts match the ordering code BFP740FH6327XTSA1 and the marking R7s on the TSFP-4-1 package. Ensure handling procedures account for ESD sensitivity as specified in the datasheet to prevent damage during assembly.

Selection Notes

Select this component for designs requiring low noise amplification in the sub-10 GHz range. The device is optimized for operation at 3 V supply voltage. Consider the thermal resistance of 300 K/W when designing heat dissipation strategies. Verify that the required bias current aligns with the optimal noise and linearity points defined in the electrical characteristics tables.

Part Context

This part belongs to the BFP740 series of RF bipolar transistors from Infineon Technologies. The suffix H6327 indicates specific tape-and-reel packaging configuration. The device is qualified for industrial applications according to JEDEC standards. It serves as a core active element in RF front-end modules where signal integrity and gain are critical parameters.

Replacement Considerations

Direct replacement requires matching the TSFP-4-1 package and pinout configuration. Substitutes must exhibit comparable fT values and noise figures within the target frequency band. Verify that alternative components support the required 4.0 V collector-emitter voltage rating and similar power dissipation limits.
