RF NPN transistor for low-noise front-ends and driver stages
The Infineon BFR35APE6327HTSA1 is an NPN silicon RF transistor in a SOT-23-3 surface-mount package, with a 5 GHz transition frequency and gain range of 10.5 dB to 16 dB. The noise figure sits at 1.4 dB to 2 dB across 900 MHz to 1.8 GHz.
Key ratings and what they mean for the BOM
Collector-emitter breakdown is rated at 15 V. Maximum collector current is 45 mA. Power dissipation maxes at 280 mW. DC current gain is a minimum of 70 at 15 mA, 8 V — a consistent beta that simplifies bias network design across the production spread.
Package and mounting
Supplied in the standard SOT-23-3 footprint (TO-236-3 / SC-59), with supplier device package PG-SOT23. The part is surface-mount only; no through-hole variant exists. Tape & Reel or Cut Tape options cover both prototype and volume reflow.
