The 250 MHz transition frequency supports switching into the tens of MHz range. ## hFE of 125 at 2 mA — drive margin for low-current loads The minimum DC current gain of 125 at only 2 mA collector current means this transistor delivers solid gain even in low-bias conditions. For a 10 mA load, a base drive of just 80 µA suffices, keeping the upstream driver (GPIO pin or previous stage) lightly loaded. The gain is specified at 5 V Vce, which matches typical 5 V logic rails. If the application runs at 3.3 V, the gain will be slightly lower, but the 125 floor at 5 V still provides comfortable headroom for most small-signal switching. For BOM planning, the active status means standard lead times through distribution apply, and no allocation or LTB scheduling is required. ## SOT-23-3 footprint and 330 mW power ceiling The transistor is supplied in a PG-SOT23-3-1 package (standard SOT-23-3 footprint). The 330 mW maximum power dissipation at 25 °C ambient is typical for this package. For continuous operation near the 100 mA collector current, derate for ambient temperature: at 85 °C the allowable dissipation drops to roughly 200 mW (derating ~2.8 mW/°C above 25 °C). The 150 °C junction temperature rating allows short-duration excursions in under-hood or engine-bay environments, but sustained high-current operation should be verified against the thermal resistance.","metaTitle":"Infineon BC856AE6327 PNP Transistor, AEC-Q101, 65 V, 100 mA","metaDescription":"Infineon BC856AE6327 PNP general-purpose transistor, AEC-Q101 qualified, 65 V Vceo, 100 mA Ic, hFE 125 min at 2 mA, 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":"125 @ 2mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"65 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.0200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BC856AE6327/alternatives.json"},"ai":{"faq":[{"question":"What is the hFE of BC856AE6327?","answer":"The minimum DC current gain (hFE) is 125 at a collector current of 2 mA and collector-emitter voltage of 5 V.
