BFP780H6327XTSA1

BFP780H6327XTSA1 Description

The BFP780H6327XTSA1 is an NPN RF bipolar transistor from Infineon Technologies, designed for high-frequency applications up to 900MHz transition frequency. With a collector-emitter breakdown voltage of 6.1V and a maximum collector current of 120mA, it delivers robust performance in RF amplification circuits. Packaged in a SOT343 (SC-70) surface-mount form factor, it is optimized for compact, high-density PCB designs. Although marked as obsolete, it remains a reliable choice for legacy systems due to its low noise figure (1.2dB–2.4dB @ 900MHz–3.5GHz) and high gain (27dB).
