It integrates two 47 kOhm resistors — one in series with the base (R1) and one from base to emitter (R2) — so the designer can drop it into a switching or driver stage without adding external bias resistors. Collector-emitter breakdown is rated at 50 V, continuous collector current at 100 mA, and the transition frequency hits 100 MHz, making it suitable for low-power switching up to medium-speed digital loads like relay coils, small-signal level shifters, or LED drivers in space-constrained consumer and industrial PCBs. The BCR 148F carries an obsolete lifecycle status. Any stock you find will be new-old-stock or pulled from overruns, so traceability and date-code freshness matter. ## SOT-723 footprint — what the package means for rework and layout The SOT-723 package (also designated PG-TSFP-3 by Infineon) is a three-lead, 1.2 mm × 1.2 mm body with a 0.4 mm lead pitch. It is one of the smallest discrete transistor packages available, which saves board area but demands careful stencil design and reflow profiling. For rework, a hot-air station with a fine nozzle is needed; the small body makes hand-soldering impractical. The 250 mW maximum power dissipation is a package-level limit — derate it for ambient temperature above 25 °C, and ensure the PCB copper area provides adequate heat sinking if the part runs near that ceiling.","metaTitle":"BCR 148F E6327 NPN Pre-Biased Transistor, 50 V, 100 mA","metaDescription":"Infineon BCR 148F E6327 NPN pre-biased transistor in SOT-723. 50 V Vce, 100 mA Ic, 47 kΩ integrated resistors, 100 MHz ft.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Power - Max":"250 mW","Mounting Type":"Surface Mount","Package / Case":"SOT-723","Product Status":"Obsolete","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR 148","Resistor - Base (R1)":"47 kOhms","Frequency - Transition":"100 MHz","Supplier Device Package":"PG-TSFP-3","Resistor - Emitter Base (R2)":"47 kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"100 mA","Current - Collector Cutoff (Max)":"100nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"70 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/48b524a21f70ba87148fe966031e06a7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the cross reference for BCR 148F E6327?","answer":"No official cross-reference is listed in the record.
