This built-in bias network cuts external component count, useful when you need a simple switch or driver on a tight board. Collector current is rated to 100 mA, with a collector-emitter breakdown of 50 V and transition frequency of 130 MHz. ## Sizing the load and drive The 100 mA collector current sets the ceiling for loads like small relays, LEDs, or logic-level interface inputs. Saturation voltage is 300 mV at 500 µA base current into 10 mA collector current, so it switches cleanly with modest base drive. For higher collector currents, check the hFE of 50 minimum at 5 mA, 5 V. ## Package and handling The PG-SOT323-3-1 supplier package is the same footprint. Maximum power dissipation is 250 mW, so keep an eye on the thermal budget if driving near the current limit continuously.","metaTitle":"Infineon BCR141W NPN Pre-Biased Transistor, SC-70, 100 mA","metaDescription":"Infineon BCR141W NPN pre-biased transistor in SC-70 (SOT-323) package. 100 mA collector current, 50 V VCEO, 22 kΩ integrated resistors.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Bulk","Power - Max":"250 mW","Mounting Type":"Surface Mount","Package / Case":"SC-70, SOT-323","Product Status":"Active","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Resistor - Base (R1)":"22 kOhms","Frequency - Transition":"130 MHz","Supplier Device Package":"PG-SOT323-3-1","Resistor - Emitter Base (R2)":"22 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":"50 @ 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/bceb8f6c0f9e9220cd52cade55a1ef6b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum collector current of BCR141W?","answer":"The maximum collector current (Ic) is 100 mA."},{"question":"What is the equivalent of BCR141W?","answer":"The BCR141W uses a unique pre-biased configuration with 22 kΩ base and emitter resistors — any substitution should match those resistor values and the SC-70 package."},{"question":"Is BCR141W RoHS compliant?","answer":"The BCR141W is listed with a Bulk package and an active lifecycle status;"}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR141W","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR141W when reusing this data.
