This is a SOT-23-3 surface-mount device rated for 200 mW power dissipation and 100 mA collector current, with a 50 V collector-emitter breakdown voltage and a 200 MHz transition frequency. The internal resistor network consists of a 10 kΩ base resistor (R1) and a 47 kΩ emitter-base resistor (R2), which eliminates the need for external biasing components and simplifies PCB layout. The part carries AEC-Q101 automotive qualification, making it suitable for under-hood and chassis-domain electronics where temperature cycling and vibration are a concern. ## R1 and R2 values — no external biasing needed The BCR185E6327 integrates a 10 kΩ base resistor (R1) and a 47 kΩ emitter-base resistor (R2). These values set the turn-on threshold and base current limit, so the transistor switches on when the input voltage exceeds roughly 2.5 V at the base pin. For a 5 V logic drive, the base current is limited to about 250 µA, which is well within the 100 mA collector current rating. The 47 kΩ resistor across the base-emitter junction also provides a guaranteed off-state with the input pulled low, reducing leakage to the 100 nA ICBO maximum. ## AEC-Q101 — qualified for automotive and industrial environments The BCR185E6327 is listed with an Automotive, AEC-Q101 qualification. For a buyer sourcing for an ECU, sensor module, or motor drive, this qualification eliminates the need for additional screening. ## SOT-23-3 package — rework and layout notes The BCR185E6327 comes in a PG-SOT23-3-1 package (SOT-23-3 footprint). The small thermal mass means it reflows cleanly with standard lead-free profiles; a hot-air station at 300 °C for a few seconds lifts the part without damaging the board pad. The package has no exposed pad, so the 200 mW power limit is the junction-to-ambient ceiling — keep the copper pour on the collector trace generous if running near the limit.","metaTitle":"BCR185E6327 PNP Pre-Biased Transistor, 200 mW, SOT-23-3","metaDescription":"BCR185E6327 PNP pre-biased transistor with 10 kΩ base resistor and 47 kΩ emitter-base resistor. 200 MHz transition frequency, 100 mA collector current.","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":"200 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Transistor Type":"PNP - Pre-Biased","lifecycle_stage":"eol_hot","Resistor - Base (R1)":"10 kOhms","Frequency - Transition":"200 MHz","Supplier Device Package":"PG-SOT23-3-1","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":"$1.0000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/772207ab758f93e7ef5fd76deb849241.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the resistor values (R1 and R2) of BCR185E6327?","answer":"The base resistor (R1) is 10 kΩ and the emitter-base resistor (R2) is 47 kΩ.
