The base resistor (R1) is 4.7 kΩ and the emitter-base resistor (R2) is 47 kΩ. Rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, with a DC current gain (hFE) minimum of 70 at 5 mA, 5 V. Transition frequency is 160 MHz, so it handles modest-speed switching cleanly. The SC-75 (SOT-416) package is about 1.6 mm x 0.8 mm — roughly half the footprint of an SOT-23. That saves board area but means the part is small under the tweezers and the hot-air nozzle. Power dissipation is 250 mW, so keep the duty cycle and ambient in check if you push near the current limit.","metaTitle":"BCR 166T E6327 PNP Pre-Biased Transistor, SC-75, 160 MHz","metaDescription":"BCR 166T E6327 PNP pre-biased transistor in SC-75 (SOT-416) package. 50 V Vce, 100 mA Ic, 160 MHz fT, integrated 4.7 kΩ / 47 kΩ resistors.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Power - Max":"250 mW","Mounting Type":"Surface Mount","Package / Case":"SC-75, SOT-416","Transistor Type":"PNP - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR 166","Resistor - Base (R1)":"4.7 kOhms","Frequency - Transition":"160 MHz","Supplier Device Package":"PG-SC-75","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/17bf34f43e30d6794a6e75cf0214e897.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the specifications of BCR 166T E6327?","answer":"It is a PNP pre-biased transistor in a SC-75 (SOT-416) surface-mount package.

The BCR 166T E6327 is the SC-75 variant. Other members of the BCR 166 family in different packages (e.g., SOT-23, SOT-323) are electrically identical but differ in footprint, so they are not pin-compatible without a board layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR-166T-E6327","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR-166T-E6327 when reusing this data.
