It integrates a 10 kΩ base resistor (R1) and a 47 kΩ emitter-base resistor (R2), eliminating two external passives per transistor and simplifying PCB layout in high-density modules. With a 50 V collector-emitter breakdown voltage and 100 mA continuous collector current rating, it comfortably handles 12 V and 24 V automotive loads with derating margin for load-dump transients. The 200 MHz transition frequency supports switching in gate drive, level shifting, and signal conditioning circuits up to the low-MHz range. ## Built-in resistors — what they save on the BOM The integrated 10 kΩ base resistor and 47 kΩ emitter-base resistor mean this single SOT-323 component replaces a discrete PNP transistor plus two chip resistors. For a 100-piece BOM line, that is 200 fewer passives to source, place, and inspect. The resistor ratio sets a fixed base current division, so the saturation voltage is predictable: 300 mV maximum at 500 µA base drive and 10 mA collector current. The DC current gain is a minimum of 70 at 5 mA collector current and 5 V VCE. ## Automotive-grade screening — what AEC-Q101 means for reliability The AEC-Q101 qualification means this part has passed stress tests for temperature cycling, high-temperature reverse bias, and humidity bias, among others. It is rated for the automotive temperature range typical of under-hood and cabin electronics. ## Package and footprint — SOT-323 layout notes The BCR185WH6327 is supplied in the PG-SOT323-3-1 package (SC-70 equivalent), a 3-pin surface-mount package with a 1.3 mm body width and 0.65 mm lead pitch. The collector is the center pin; the base and emitter are on the outer pins. Maximum power dissipation is 250 mW, so thermal design should account for ambient temperature and board copper area. The part is rated for surface-mount assembly and is compatible with standard reflow profiles.","metaTitle":"BCR185WH6327 PNP Pre-Biased Transistor, AEC-Q101, 200 MHz","metaDescription":"Infineon BCR185WH6327 PNP pre-biased transistor in SC-70/SOT-323, AEC-Q101 qualified, 50 V, 100 mA, 200 MHz fT, 250 mW.","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":"PNP - Pre-Biased","lifecycle_stage":"eol_hot","Resistor - Base (R1)":"10 kOhms","Frequency - Transition":"200 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":"$0.0400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a85953cf4f3d8fe4518e840d942b31ea.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the equivalent of BCR185WH6327?","answer":"The BCR185WH6327 is a pre-biased PNP transistor with a specific resistor ratio (10 kΩ base, 47 kΩ emitter-base).
