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.","metaTitle":"Infineon BFP420H6801 RF Transistor NPN, 25 GHz, 21 dB Gain","metaDescription":"Infineon BFP420H6801 NPN RF transistor in SC-82A SOT-343. 25 GHz fT, 21 dB gain, 1.1 dB noise figure at 1.8 GHz. 210 mW max.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":[],"specifications":{"Gain":"21dB","Package":"Bulk","Power - Max":"210mW","Mounting Type":"Surface Mount","Package / Case":"SC-82A, SOT-343","Transistor Type":"NPN","lifecycle_stage":"eol_hot","Operating Temperature":"150°C (TJ)","Frequency - Transition":"25GHz","Supplier Device Package":"PG-SOT343-4-2","Noise Figure (dB Typ @ f)":"1.1dB @ 1.8GHz","Current - Collector (Ic) (Max)":"60mA","DC Current Gain (hFE) (Min) @ Ic, Vce":"60 @ 20mA, 4V","Voltage - Collector Emitter Breakdown (Max)":"4.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.18","priceTiers":[{"qty":1641,"price":"$0.18000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/379e331d7db033200602e6f58043f713.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BFP420H6801/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum power dissipation of BFP420H6801?","answer":"The maximum power dissipation is 210 mW.
