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 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.","metaTitle":"BFR505215 NPN RF Transistor, 9 GHz fT, SOT-23","metaDescription":"BFR505215 NPN RF transistor, 9 GHz transition frequency, 1.2 dB noise figure at 900 MHz, 150 mW max power, SOT-23 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":[],"specifications":{"Package":"Bulk","Power - Max":"150mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Transistor Type":"NPN","lifecycle_stage":"eol_hot","Operating Temperature":"175°C (TJ)","Frequency - Transition":"9GHz","Supplier Device Package":"SOT-23 (TO-236AB)","Noise Figure (dB Typ @ f)":"1.2dB ~ 2.1dB @ 900MHz","Current - Collector (Ic) (Max)":"18mA","DC Current Gain (hFE) (Min) @ Ic, Vce":"60 @ 5mA, 6V","Voltage - Collector Emitter Breakdown (Max)":"15V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.15","priceTiers":[{"qty":2061,"price":"$0.15000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d2be4db43356949cc84bd2aea4956a06.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BFR505215/alternatives.json"},"ai":{"faq":[{"question":"Is BFR505215 obsolete?","answer":"No — the lifecycle status is Active. NXP is still producing this part; there is no last-time-buy or end-of-life notice."},{"question":"What is the max frequency of BFR505215?","answer":"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."},{"question":"Is BFR505215 equivalent to BFR92?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp/BFR505215","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp/BFR505215 when reusing this data.
