BFP 740F E6327

Overview

The BFP 740F E6327 is an NPN silicon-germanium (SiGe) RF bipolar transistor manufactured by Infineon Technologies. It operates at a transition frequency of 42 GHz with a maximum collector-emitter voltage of 4 V and an emitter-base voltage of 1.2 V. The device supports a continuous collector current of 30 mA and dissipates up to 160 mW of power. It is housed in a TSFP-4 surface-mount package, suitable for automated SMD/SMT assembly. The component functions as a single configuration transistor within the BFP740 series.

Feature Summary

• Utilizes SiGe technology for high-frequency performance
• Designed for RF applications requiring low noise characteristics
• Qualified for automotive electronics via AEC-Q100 standards

Applications

• Low-noise amplifier stages in wireless communication systems
• Front-end modules for WLAN and GNSS receivers
• RF signal processing in automotive infotainment units

Procurement Notes

Verify end-of-life status before integration. Confirm RoHS compliance details through official documentation. Check for alternative packaging options such as cut tape or reel if standard availability is limited. Ensure design-in compatibility with existing PCB footprints for the TSFP-4 package type.

Selection Notes

Compare against the BFP 740F H6327 variant for potential upgrades or replacements. Evaluate thermal management requirements given the 160 mW power dissipation limit. Consider the 42 GHz frequency specification when designing matching networks for target operating bands.

Part Context

This component belongs to the BFP740 series of RF bipolar transistors. It shares architectural similarities with other members like the BFP 740 E6327 but utilizes specific suffix codes indicating manufacturing lot or packaging variations. The TSFP-4 package distinguishes it from SOT-343 variants found in the broader family.

Replacement Considerations

The BFP 740F H6327 is listed as a possible replacement. Verify pinout and electrical parameter equivalence before substitution.
