BFP740FESD H6327 – INFINEON

The BFP740FESD H6327 is a silicon NPN bipolar RF transistor manufactured by Infineon Technologies, fabricated using their advanced high-frequency process. It’s housed in a TSFP-4-1 (Thin Small Flat Package with 4 leads) offering a compact footprint for space-constrained applications. This transistor is specifically designed for low-noise and high-gain amplification in the GHz frequency range. Key performance parameters include a transition frequency (fT) typically exceeding 80 GHz and a maximum oscillation frequency (fmax) around 90 GHz. The integrated ESD protection circuitry provides robustness against electrostatic discharge events, enhancing reliability during handling and operation. Typical applications include low-noise amplifiers (LNAs) in wireless communication systems such as WLAN, GPS, and cellular infrastructure, as well as high-frequency oscillators and mixers. The TSFP-4-1 package exhibits low parasitic inductance and capacitance, contributing to the device’s excellent high-frequency performance.
