The integrated bias resistors (R1 = 22 kOhms, R2 = 22 kOhms) eliminate two external resistors, simplifying PCB layout and reducing component count. Rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, it handles common automotive loads like relay drivers, solenoid drivers, and logic-level interface circuits. The 200 MHz transition frequency means it switches cleanly in low-speed PWM or digital on/off applications without excessive switching loss. ## AEC-Q101 qualification — built for automotive reliability This part carries AEC-Q101 qualification, the automotive stress-test standard for discrete semiconductors. That means it has passed rigorous temperature cycling, high-temperature reverse bias, and humidity tests specified for under-hood and chassis-mounted electronics. The Automotive grade confirms the operating temperature range and reliability targets align with OEM requirements for engine control units, body controllers, and transmission modules. For a design targeting automotive PPAP, this qualification is a checkbox item — the BCR191WE6327 already meets it. ## 250 mW power dissipation in a small SMD package Maximum power dissipation is 250 mW in the SC-70/SOT-323 package. The base product number BCR191 covers a family of pre-biased transistors, so if a different resistor ratio or package variant is needed, the family provides drop-in alternatives without requalification.","metaTitle":"Infineon BCR191WE6327 PNP Pre-Biased Transistor, AEC-Q101","metaDescription":"Infineon BCR191WE6327 PNP pre-biased digital transistor, AEC-Q101 qualified, 50 V Vce, 100 mA Ic, 250 mW, SC-70/SOT-323.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Grade":"Automotive","Series":"-","Package":"Bulk","Power - Max":"250 mW","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"SC-70, SOT-323","Product Status":"Active","Transistor Type":"PNP - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR191","Resistor - Base (R1)":"22 kOhms","Frequency - Transition":"200 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":"$0.0200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f5d66bcfa31fa77dda4f957b6d98317c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR191WE6327 AEC-Q101 qualified?","answer":"Yes, it is AEC-Q101 qualified, making it suitable for automotive applications that require this qualification level."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR191WE6327","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR191WE6327 when reusing this data.
