Its headline figures — 22 dB gain at 900 MHz, 0.7 dB noise figure at the same frequency, and an 11 GHz transition frequency — make it a fit for receiver front-ends, VCO buffer stages, and driver amplifiers in automotive RF modules (telematics, keyless entry, tire-pressure monitoring) and industrial wireless links. At 900 MHz the BFU530XAR delivers 22 dB of gain with a noise figure of 0.7 dB. In a typical LNA stage that means the transistor adds very little noise while providing enough gain to overcome the noise floor of a following mixer or SAW filter. The 11 GHz fT gives headroom for designs up to 2.4 GHz or higher with derated gain — useful for dual-band automotive receivers that cover both sub-GHz ISM and 2.4 GHz bands. ## Automotive-grade qualification and temperature range AEC-Q101 qualification means the part has passed the stress tests required for automotive-grade discrete semiconductors: HBM ESD, pre-conditioning, high-temperature reverse bias, and temperature cycling. ## Active lifecycle — no LTB concern If a second-source or pin-compatible alternative is needed for dual-sourcing, no direct cross-reference is confirmed here — the SOT-143B footprint is shared with other NXP RF transistors. ## SOT-143B footprint and automated assembly The SOT-143B package is a four-lead variant of the SOT-143 with a collector pad layout common among NXP RF transistors.","metaTitle":"NXP BFU530XAR RF Transistor NPN 12V 11GHz SOT143B, AEC-Q101","metaDescription":"NXP BFU530XAR RF NPN transistor, 22 dB gain at 900 MHz, 0.7 dB noise figure, AEC-Q101 qualified, SOT143B.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Gain":"22dB","Grade":"Automotive","Package":"Tape & Reel (TR); Cut Tape (CT)","Power - Max":"450mW","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"TO-253-4, TO-253AA","Transistor Type":"NPN","lifecycle_stage":"eol_hot","Operating Temperature":"-40°C ~ 150°C (TJ)","Frequency - Transition":"11GHz","Supplier Device Package":"SOT-143B","Noise Figure (dB Typ @ f)":"0.7dB @ 900MHz","Current - Collector (Ic) (Max)":"40mA","DC Current Gain (hFE) (Min) @ Ic, Vce":"60 @ 10mA, 8V","Voltage - Collector Emitter Breakdown (Max)":"12V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.48","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.49000","currency":"USD"},{"qty":10,"price":"$0.41800","currency":"USD"},{"qty":25,"price":"$0.39040","currency":"USD"},{"qty":100,"price":"$0.31220","currency":"USD"},{"qty":250,"price":"$0.28992","currency":"USD"},{"qty":500,"price":"$0.24530","currency":"USD"},{"qty":1000,"price":"$0.18956","currency":"USD"},{"qty":3000,"price":"$0.17283","currency":"USD"},{"qty":6000,"price":"$0.16168","currency":"USD"},{"qty":15000,"price":"$0.15053","currency":"USD"},{"qty":30000,"price":"$0.14273","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2a40b9805dfad537f6aa1a018ebbf8cf.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BFU530XAR AEC-Q101 qualified for automotive use?","answer":"Yes, the BFU530XAR is AEC-Q101 qualified, making it suitable for automotive-grade applications including under-hood and exterior modules."},{"question":"Does BFU530XAR come in tape and reel for automated assembly?","answer":"Yes, the BFU530XAR is available in Tape & Reel (TR) packaging, which is suitable for automated pick-and-place assembly.
