It integrates two 22 kOhm resistors — one in series with the base (R1) and one between the emitter and base (R2) — so it switches on with a positive base voltage relative to the emitter, no external bias resistors needed. Collector-emitter breakdown is rated at 50 V, continuous collector current at 100 mA, and the transition frequency hits 200 MHz, making it suitable for low-speed switching and driver stages in compact, cost-sensitive designs. Infineon has marked the BCR191WE6327HTSA1 as Obsolete. The 50 V VCEO and 100 mA Ic ceiling define the operating window for a substitute. The 300 mV saturation voltage at 500 µA base drive and 10 mA collector current is typical for a pre-biased PNP — a replacement should match or beat that to avoid excess dissipation in the on-state. The 200 MHz fT is adequate for switching up to a few megahertz; a faster device would work but may cost more. The SC-70 footprint is the mechanical constraint — any drop-in alternate must be in the same SOT-323 package.","metaTitle":"BCR191WE6327HTSA1 PNP Pre-Biased Transistor, 50 V, 100 mA","metaDescription":"Infineon BCR191WE6327HTSA1 PNP pre-biased transistor, 50 V VCEO, 100 mA Ic, 200 MHz fT, SC-70 SMD.","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":"250 mW","Mounting Type":"Surface Mount","Package / Case":"SC-70, SOT-323","Product Status":"Obsolete","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","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://www.infineon.com/dgdl/bcr191series.pdf?folderId=db3a30431400ef68011406f3ddb1012e&fileId=db3a30431428a3730114404180e802d7","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR191WE6327HTSA1 obsolete?","answer":"Yes, Infineon lists the BCR191WE6327HTSA1 as Obsolete.
