Each transistor integrates two 47kΩ resistors — one in series with the base (R1) and one from base to emitter (R2) — eliminating the need for external bias resistors in low-current switching applications. With a collector-emitter breakdown voltage of 50V and a maximum collector current of 100mA, it is suited for driving small relays, LEDs, or logic-level loads from a microcontroller output without additional components. The 100MHz transition frequency supports switching up to moderate-speed digital signals. ## Obsolete — sourcing through independent distribution The BCR148SE6327BTSA1 carries an obsolete lifecycle status. ## Key ratings for the BOM decision The 50V collector-emitter breakdown voltage sets the maximum rail voltage for the switching load — adequate for 24V industrial logic or 12V automotive auxiliary circuits. The 100mA collector current limit per transistor means each output drives a load drawing up to 100mA; for higher current, parallel the two NPN stages or select a higher-rated device. The 250mW total power dissipation (package limit) governs thermal derating: at 85°C ambient, derate to roughly 160mW. The 47kΩ base resistor (R1) and 47kΩ base-emitter resistor (R2) provide a fixed bias that turns the transistor fully on with a 3.3V or 5V logic-level input, simplifying the drive interface.","metaTitle":"Infineon BCR148SE6327BTSA1 Dual NPN Pre-Biased Transistor","metaDescription":"Infineon BCR148SE6327BTSA1 dual NPN pre-biased transistor, 50V VCEO, 100mA IC, 250mW.","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":"250mW","Mounting Type":"Surface Mount","Package / Case":"6-VSSOP, SC-88, SOT-363","Product Status":"Obsolete","Transistor Type":"2 NPN - Pre-Biased (Dual)","lifecycle_stage":"eol_hot","Base Product Number":"BCR148","Resistor - Base (R1)":"47kOhms","Frequency - Transition":"100MHz","Supplier Device Package":"PG-SOT363-PO","Resistor - Emitter Base (R2)":"47kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"100mA","Current - Collector Cutoff (Max)":"-","DC Current Gain (hFE) (Min) @ Ic, Vce":"70 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/48b524a21f70ba87148fe966031e06a7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BCR148SE6327BTSA1?","answer":"For a pin-compatible alternative, evaluate other dual NPN pre-biased transistor arrays in the SOT-363 package from Infineon or second-source manufacturers, verifying the resistor values (R1 = 47kΩ, R2 = 47kΩ) and 50V VCEO rating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR148SE6327BTSA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR148SE6327BTSA1 when reusing this data.
