This eliminates two external passive components from the BOM for simple switching and interface applications — the transistor turns on when the base drive exceeds the resistor divider threshold, with no external bias network to design or place. Rated for 50 V collector-emitter breakdown and 70 mA continuous collector current, with a transition frequency of 150 MHz. ## SC-75 SOT-416 footprint Packaged in the 3-pin SC-75 (SOT-416) case — supplier device code PG-SC75-3D — this is a small surface-mount footprint suited for dense PCB layouts. The 250 mW power dissipation ceiling limits continuous current in free-air; derate per the thermal resistance for the board copper area you allocate. ## Obsolete — sourcing reality Infineon lists the BCR 146T as Obsolete. Sourcing is limited to the independent distribution channel — new-old-stock and surplus inventory only.","metaTitle":"BCR 146T E6327 NPN Pre-Biased Transistor, 50V 70mA 150MHz","metaDescription":"BCR 146T E6327 NPN pre-biased transistor from Infineon. 50 V Vceo, 70 mA Ic, 150 MHz fT, integrated 47 kΩ base and 22 kΩ emitter-base resistors.","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":"SC-75, SOT-416","Product Status":"Obsolete","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR 146","Resistor - Base (R1)":"47 kOhms","Frequency - Transition":"150 MHz","Supplier Device Package":"PG-SC75-3D","Resistor - Emitter Base (R2)":"22 kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"70 mA","Current - Collector Cutoff (Max)":"100nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"50 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/595f0465aa4fdf992e12507312ef2506.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BCR 146T E6327?","answer":"Infineon has not published an official successor for this order code.
