It is housed in a PG-SOT23 surface-mount package (equivalent to TO-236-3 / SC-59 / SOT-23-3) and rated for a maximum collector current of 500 mA with a collector-emitter breakdown voltage of 45 V. The DC current gain (hFE) at 100 mA / 1 V is a minimum of 100 — the -16 gain group — and the transition frequency is 170 MHz. With a junction temperature rating of 150°C and 500 mW maximum power dissipation, this part is suited for switching and linear amplification in 12 V and 24 V automotive electrical systems, engine control modules, body electronics, and industrial control boards where the AEC-Q101 pedigree provides the PPAP-ready documentation an OEM auditor expects. The 500 mA maximum collector current (Ic) is the continuous rating; the part can handle higher peak currents as long as the junction temperature stays within the 150°C TJ limit. For a typical automotive relay or solenoid driver, leaving 20 % derating margin means sizing the load to 400 mA or less. The 45 V VCEO breakdown provides adequate headroom for 12 V and 24 V systems, including load-dump transients that can exceed 40 V in an unclamped 12 V bus. ## hFE of 100 at 100 mA — gain for saturated switching The minimum DC current gain of 100 at Ic = 100 mA / VCE = 1 V means the base drive requirement is roughly 1 mA per 100 mA of collector current. For a 500 mA load, a base current of 5 mA saturates the transistor with VCE(sat) typically under 700 mV. This gain group (-16) covers hFE values from 100 to 250, giving consistent saturation behaviour across the reel. The 100 nA maximum collector cut-off current (ICBO) ensures negligible leakage at high temperature, important in automotive off-state current budgets.","metaTitle":"Infineon BC817K-16E6327 NPN Transistor, AEC-Q101, 500 mA","metaDescription":"Infineon BC817K-16E6327 NPN transistor, AEC-Q101 qualified, 45 V VCEO, 500 mA Ic, hFE min 100, 170 MHz fT, SOT-23 package, 150°C TJ.","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":"500 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","lifecycle_stage":"eol_hot","Operating Temperature":"150°C(TJ)","Frequency - Transition":"170MHz","Supplier Device Package":"PG-SOT23","Vce Saturation (Max) @ Ib, Ic":"700mV @ 50mA, 500mA","Current - Collector (Ic) (Max)":"500 mA","Current - Collector Cutoff (Max)":"100nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"100 @ 100mA, 1V","Voltage - Collector Emitter Breakdown (Max)":"45 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.0300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b4e378390df63bd31f55c7981ea55926.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BC817K-16E6327 automotive qualified?","answer":"Yes. The BC817K-16E6327 is listed under the Automotive, AEC-Q101 series, meaning it has passed the AEC-Q101 stress tests for discrete semiconductors — including high-temperature operating life, temperature cycling, and humidity bias."},{"question":"What is the maximum collector current of BC817K-16E6327?","answer":"The maximum continuous collector current (Ic) is 500 mA. The part can also handle higher pulsed currents as long as the 500 mW power dissipation and 150°C junction temperature limits are not exceeded. For design margin, derate to 400 mA continuous in a 12 V automotive system."},{"question":"What is the hFE of BC817K-16E6327?","answer":"The DC current gain (hFE) for the -16 gain group is a minimum of 100 at Ic = 100 mA / VCE = 1 V, with a typical spread up to 250. This is the same gain group as the standard BC817-16, so the part is a drop-in replacement for that device in AEC-Q101 applications."},{"question":"Can BC817K-16E6327 be used for switching applications?","answer":"Yes. With a transition frequency of 170 MHz and a VCE(sat) of 700 mV max at 50 mA base / 500 mA collector, it is well suited for saturated switching of relays, solenoids, LEDs, and low-power loads in automotive and industrial circuits. The 100 nA maximum off-state leakage keeps the load off when the base drive is removed."},{"question":"What is the closest pin-compatible alternative to BC817K-16E6327?","answer":"The Infineon BC817-16 (non-automotive grade) is the same die in the same SOT-23 package with identical pinout and DC current gain. The key difference is the AEC-Q101 qualification: the BC817K-16E6327 carries the automotive stress-test pedigree, while the BC817-16 is typically listed as commercial/industrial. For a non-automotive BOM, the BC817-16 is a cost-effective second-source option. For automotive programs requiring AEC-Q101, the BC817K-16E6327 remains the correct choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BC817K-16E6327","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BC817K-16E6327 when reusing this data.
