Transition frequency of 85GHz and typical gain of 35dB. ## Package and mounting for RF layout The PG-TSFP-4-1 package is a 4-lead flat-lead SMD with a small footprint — the leads are coplanar with the body, which minimizes parasitic inductance and supports repeatable RF performance up to several tens of gigahertz. Surface-mount assembly is standard; the flat leads require a solder paste stencil aperture sized to the pad geometry in the Infineon application note. The device is rated for a junction temperature of 150°C, so thermal management is straightforward at the 75mW maximum power dissipation. ## Lifecycle and compliance It is ROHS3 compliant, which covers the current EU RoHS exemption list.","metaTitle":"Infineon BFP840FESDH6327XTSA1 RF NPN Transistor, 85GHz","metaDescription":"Infineon BFP840FESDH6327XTSA1 NPN RF transistor with 85GHz fT, 35dB gain, 0.75dB NF @ 5.5GHz.
