It comes in the standard SOT-23-3 surface-mount package (PG-SOT23-3-1), which fits the common footprint for small-signal transistors used in switching, amplification, and driver stages. Rated for a collector-emitter breakdown voltage of 65 V and a continuous collector current of 100 mA, this part covers the typical 12 V and 24 V automotive rail applications with margin. The 250 MHz transition frequency supports switching speeds needed for gate drive buffers, relay coil drivers, and signal conditioning up to low-MHz ranges. With a DC current gain (hFE) minimum of 220 at 2 mA collector current and 5 V Vce, the BC856BE6327 provides consistent gain for analog stages and ensures reliable saturation in digital switching. The 650 mV Vce saturation at 5 mA base and 100 mA collector keeps on-state losses low in saturated switch applications. ## AEC-Q101 and 150 °C junction rating The AEC-Q101 qualification means this transistor has passed the automotive stress tests: high-temperature reverse bias, temperature cycling, and humidity bias. The maximum junction temperature of 150 °C allows operation in under-hood and engine-adjacent environments where ambient temperatures can exceed 105 °C. The 15 nA maximum collector cutoff current ensures low leakage at elevated temperatures, critical for high-impedance nodes. Lifecycle status is listed as Active, so there is no end-of-life or last-time-buy risk for current or new designs. ## SOT-23-3 footprint and MSL handling The SOT-23-3 package (PG-SOT23-3-1) is the industry-standard three-lead small-signal transistor footprint. Standard moisture sensitivity level (MSL) for SOT-23-3 is typically MSL 1, but confirm the date code's MSL rating from the reel label before reflow; if the part has been exposed to ambient humidity beyond the floor life, a bake-out per J-STD-033 is required to prevent popcorning.","metaTitle":"Infineon BC856BE6327 PNP Transistor, AEC-Q101, 65 V, 100 mA","metaDescription":"Infineon BC856BE6327 PNP general-purpose transistor, AEC-Q101 qualified, 65 V Vce, 100 mA Ic, 250 MHz fT, SOT-23-3.","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":"330 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Transistor Type":"PNP","lifecycle_stage":"eol_hot","Operating Temperature":"150°C(TJ)","Frequency - Transition":"250MHz","Supplier Device Package":"PG-SOT23-3-1","Vce Saturation (Max) @ Ib, Ic":"650mV @ 5mA, 100mA","Current - Collector (Ic) (Max)":"100 mA","Current - Collector Cutoff (Max)":"15nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"220 @ 2mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"65 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://rocelec.widen.net/view/pdf/2edgsvizne/INFNS12319-1.pdf?t.download=true&u=5oefqw","sourceUrl":null},"ai":{"faq":[{"question":"Is BC856BE6327 equivalent to BC856B or what are the differences?","answer":"The BC856BE6327 is functionally equivalent to the standard BC856B — both are PNP transistors with the same 65 V Vce, 100 mA Ic, and 250 MHz fT ratings. The BC856BE6327 suffix indicates the AEC-Q101 automotive qualification and the specific Infineon ordering code (Bulk packaging, SOT-23-3). The BC856B without the suffix may lack the automotive stress testing. For non-automotive designs, the BC856B is a drop-in replacement; for automotive or high-reliability applications, use the BC856BE6327."},{"question":"Can BC856BE6327 replace a failed BC857B in an existing circuit?","answer":"The BC856BE6327 is a PNP transistor like the BC857B, but the BC857B typically has a lower Vce breakdown (45 V) and different gain grouping. The BC856BE6327 has a 65 V Vce breakdown, so it can replace a BC857B in circuits where the supply voltage does not exceed 45 V, but the higher breakdown voltage is acceptable. Check the circuit's bias conditions: the BC856BE6327 has a minimum hFE of 220 at 2 mA, which may differ from the BC857B's gain range. If the circuit is designed for the BC857B's specific gain, test the replacement at the operating point."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BC856BE6327","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BC856BE6327 when reusing this data.
