Product details

9 GHz RF transistor in a SOT-23 — what you get

The BFR505215 is an NPN RF transistor with a 9 GHz transition frequency. Noise figure is 1.2 dB to 2.1 dB at 900 MHz. Collector current max is 18 mA, Vceo max is 15 V. Package is SOT-23.

Active lifecycle — no obsolescence watch needed

The BFR505215 carries an Active lifecycle status. That means NXP is still manufacturing it, no last-time-buy notice, no NRND flag. For a BOM freeze or a long-production-run design, this part does not carry supply-chain risk from obsolescence.

Frequently asked questions

Is BFR505215 obsolete?

No — the lifecycle status is Active. NXP is still producing this part; there is no last-time-buy or end-of-life notice.

What is the max frequency of BFR505215?

The transition frequency (fT) is 9 GHz. That is the frequency at which current gain drops to unity — practical amplifier gain is useful well below that, typically up to 2–3 GHz in a common-emitter stage.

Is BFR505215 equivalent to BFR92?

The BFR92 is also an NPN RF transistor in SOT-23, but its fT is typically 5 GHz, lower than the 9 GHz of the BFR505215. The BFR505215 offers higher gain at UHF frequencies. They are not drop-in equivalents — check the bias conditions and gain requirements before substituting.
