That pre-biased arrangement cuts external component count — no separate resistor needed per transistor — which matters when you are squeezing a switching function into a tight layout. Each transistor handles up to 50V collector-emitter breakdown and 100mA continuous collector current, with a transition frequency of 150MHz. The 250mW power ceiling covers both transistors combined, so keep the total dissipation in mind when driving both channels simultaneously. ## Where it fits — low-current digital switching This dual transistor is a fit for board-level switching where you need to invert or buffer logic signals, drive a small relay coil, or level-shift a few milliamps. The integrated base resistor means the base drive is set by the 10kΩ value — the transistor turns on when the input exceeds roughly 0.7V plus the drop across that resistor. Surface-mount assembly in the SOT-363 footprint keeps the placement cost low.","metaTitle":"BCR129SE6327HTSA1 Dual NPN Pre-Biased Transistor, 50V 100mA","metaDescription":"Infineon BCR129SE6327HTSA1 dual NPN pre-biased transistor, 50V VCEO, 100mA IC, 150MHz fT, SOT-363.","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","Resistor - Base (R1)":"10kOhms","Frequency - Transition":"150MHz","Supplier Device Package":"PG-SOT363-PO","Resistor - Emitter Base (R2)":"-","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"100mA","Current - Collector Cutoff (Max)":"-","DC Current Gain (hFE) (Min) @ Ic, Vce":"120 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3231f9fc17c6083a26de9556ff594490.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR129SE6327HTSA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR129SE6327HTSA1 when reusing this data.
