The 4.2 V collector-emitter breakdown and 45 mA maximum collector current set a low-voltage bias point. The 4-TSFP package keeps parasitic inductance low and suits automated pick-and-place assembly. A 47 GHz transition frequency means the transistor delivers useful gain into the microwave region. The part is rated for operation through 10 GHz based on the noise-figure test points. The 160 mW maximum power dissipation is a board-level constraint. No last-time-buy or end-of-life notices are on record for this order code. For high-volume pick-and-place, verify that the feeder system can handle loose parts, or request the tape-and-reel variant if available under a different suffix.","metaTitle":"BFP740FESDH6327 NPN RF Transistor, 47 GHz fT, 39 dB Gain","metaDescription":"BFP740FESDH6327 NPN RF transistor in 4-TSFP package. 47 GHz transition frequency, 39 dB gain, 0.5 dB noise figure.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":[],"specifications":{"Gain":"39dB","Package":"Bulk","Power - Max":"160mW","Mounting Type":"Surface Mount","Package / Case":"4-SMD, Flat Leads","Transistor Type":"NPN","lifecycle_stage":"eol_hot","Operating Temperature":"150°C (TJ)","Frequency - Transition":"47GHz","Supplier Device Package":"4-TSFP","Noise Figure (dB Typ @ f)":"0.5dB ~ 1.45dB @ 150MHz ~ 10GHz","Current - Collector (Ic) (Max)":"45mA","DC Current Gain (hFE) (Min) @ Ic, Vce":"160 @ 25mA, 3V","Voltage - Collector Emitter Breakdown (Max)":"4.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.17","priceTiers":[{"qty":1745,"price":"$0.17000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/df3e681c19fbf4122854858689856ebb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BFP740FESDH6327/alternatives.json"},"ai":{"faq":[{"question":"Where can I find the datasheet for BFP740FESDH6327?","answer":"The datasheet for the BFP740FESDH6327 is available from Infineon's website or through the product page on this distributor site. It includes the full S-parameter data, noise-parameter circles, and recommended land pattern for the 4-TSFP package."},{"question":"What is BFP740FESDH6327's listed gain?","answer":"The BFP740FESDH6327 is specified for 39 dB gain. That figure is a small-signal gain typically measured at a low frequency (e.g., 100 MHz) and a given bias; at microwave frequencies the gain rolls off according to the S-parameters in the datasheet."},{"question":"What is the recommended operating frequency range for BFP740FESDH6327?","answer":"The noise figure is characterized from 150 MHz to 10 GHz, and the 47 GHz transition frequency supports use well into X-band (8–12 GHz). Practical LNA designs with this transistor commonly cover 0.5 GHz to 6 GHz, with careful layout extending to 10 GHz."},{"question":"Is BFP740FESDH6327 suitable for 5G infrastructure?","answer":"Yes, the 47 GHz fT and low noise figure (0.5 dB at 150 MHz) make it suitable for low-noise amplifier stages in 5G sub-6 GHz and mmWave front-end modules, particularly in the 3.5 GHz and 28 GHz bands where noise figure and gain are critical."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BFP740FESDH6327","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BFP740FESDH6327 when reusing this data.
