The integrated 4.7 kOhm base resistor (R1) eliminates one external component per switching node, simplifying board layout and reducing pick-and-place cost. It is designed for low-current switching and interface applications where a single transistor with a defined base drive is needed — common in relay drivers, logic-level translators, and small-signal amplification stages in industrial and consumer electronics. The 50 V collector-emitter breakdown voltage (VCEO) comfortably handles 24 V and 48 V industrial supply rails with margin. The 100 mA maximum collector current (IC) suits driving small relays, LEDs, or logic inputs — not power loads. The 150 MHz transition frequency (fT) is adequate for switching up to several megahertz, though the pre-biased nature limits the switching speed compared to a discrete transistor with a tailored base drive. The BCR 119 E6433 is listed as obsolete by Infineon. No official successor order code appears in the available records.","metaTitle":"BCR 119 E6433 NPN Pre-Biased Transistor, 50 V, 100 mA","metaDescription":"BCR 119 E6433 NPN pre-biased transistor with 4.7 kOhm base resistor, 50 V VCEO, 100 mA IC, 150 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":"200 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Obsolete","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR 119","Resistor - Base (R1)":"4.7 kOhms","Frequency - Transition":"150 MHz","Supplier Device Package":"PG-SOT23","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":"120 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/91bbf69fe60ecf56e9af4e7244456730.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR 119 E6433 obsolete?","answer":"Yes, Infineon lists the BCR 119 E6433 as obsolete."},{"question":"What is the base resistor value for BCR 119 E6433?","answer":"The integrated base resistor (R1) is 4.7 kOhms.
