The built-in bias network — a 2.2 kΩ series base resistor (R1) and a 47 kΩ base-emitter resistor (R2) — eliminates the need for two external passives per transistor, shrinking board area and reducing pick-and-place cost in high-density modules like engine control units, transmission controllers, or body electronics. Collector current is rated to 100 mA, and the collector-emitter breakdown voltage holds at 50 V, covering 12 V and 24 V automotive rails with margin. The 170 MHz transition frequency means this part switches cleanly into the low-MHz range, suitable for gate-drive interface, level translation, and relay or solenoid pre-driver stages. ## Saturation and gain — the real-world switching numbers Vce(sat) is specified at 300 mV maximum with a 500 µA base drive and 10 mA collector load — a typical forced-beta condition that tells you the part saturates hard enough to keep dissipation low in a logic-level switching job. Minimum DC current gain is 70 at 5 mA Ic and 5 V Vce, so the pre-biased resistor divider is designed to guarantee adequate base overdrive across the 100 mA operating range. Collector cutoff current is just 100 nA maximum, which matters for low-leakage automotive off-state requirements. The AEC-Q101 qualification certificate and the datasheet are manufacturer-published and current.","metaTitle":"Infineon BCR108WE6327 NPN Pre-Biased Transistor, AEC-Q101","metaDescription":"Infineon BCR108WE6327 NPN pre-biased transistor, AEC-Q101 qualified, 100 mA Ic, 50 V Vceo, 170 MHz fT, SC-70 SOT-323 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"Automotive, AEC-Q101","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)":"2.2 kOhms","Frequency - Transition":"170 MHz","Supplier Device Package":"PG-SOT323-3-1","Resistor - Emitter Base (R2)":"47 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":"70 @ 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/3ecc5f821fdc053cf6f765e4d80f9f0f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR108WE6327 automotive qualified?","answer":"Yes, it is listed under the Automotive series and carries AEC-Q101 qualification, making it suitable for automotive-grade applications including under-hood and cabin electronics."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR108WE6327","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR108WE6327 when reusing this data.
