Product details

X-band NPN in a tiny SOT-343

The Infineon BFP420H6801 is an NPN silicon RF transistor in a PG-SOT343-4-2 package. It has 25 GHz transition frequency and 21 dB gain.

SOT-343 — orientation and handling

The SOT-343 package is a four-lead supermini. The 150 °C junction temperature rating means it can sit near a hot PA stage.

Sourcing and lifecycle — active, no LTB clock

The BFP420H6801 carries an Active lifecycle status. Infineon still runs this part, so it is suitable for new designs and production replenishment through standard distribution.

Frequently asked questions

What is the maximum power dissipation of BFP420H6801?

The maximum power dissipation is 210 mW. This sets the thermal budget for the SOT-343 package — rely on board copper for heat sinking, not an external heatsink.

What is the gain of BFP420H6801 at typical bias?

The listed gain is 21 dB at a typical bias point. That is enough to lift a -10 dBm signal to +11 dBm into 50 Ω without an extra stage.

What is the maximum collector current of BFP420H6801?

The maximum collector current (Ic) is 60 mA. Combined with the 4.5 V Vce breakdown, this transistor is sized for small-signal stages, not power output.
