The device is housed in a standard SOT-323 (SC-70) surface-mount package, with a power dissipation ceiling of 500 mW. The 170 MHz transition frequency gives enough bandwidth for moderate-speed switching applications such as PWM fan control, lamp dimming, and low-frequency DC-DC converter drive stages. The '16' suffix in the order code denotes a DC current gain (hFE) of 100 minimum at 100 mA collector current with 1 V Vce. This is the medium-gain bin in the BC817K family, offering a good balance between saturation voltage and drive current. At the rated test point, Vce saturation is a maximum of 700 mV at 50 mA base current and 500 mA collector current, which keeps conduction losses manageable in a saturated switch. Substituting a different gain group without adjusting the base resistor may shift the saturation depth or switching speed. ## Lifecycle and sourcing posture For dual-sourcing flexibility, the BC817K family includes pin-compatible gain-group variants that share the same SOT-323 footprint and AEC-Q101 qualification, though the hFE bin differs. ## Package and reflow considerations The SOT-323 (SC-70) package is a small three-lead surface-mount body. It is compatible with standard lead-free reflow profiles.","metaTitle":"Infineon BC817K-16WH6327 NPN Transistor, AEC-Q101, 45 V","metaDescription":"Infineon BC817K-16WH6327 NPN transistor, AEC-Q101 automotive grade, 45 V Vce, 500 mA Ic, hFE 100 min, 170 MHz ft, SOT-323.","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":"SC-70, SOT-323","Product Status":"Active","lifecycle_stage":"eol_hot","Operating Temperature":"150°C(TJ)","Frequency - Transition":"170MHz","Supplier Device Package":"PG-SOT323-3-1","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b4e378390df63bd31f55c7981ea55926.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the hFE of BC817K-16WH6327?","answer":"The DC current gain (hFE) is a minimum of 100 at 100 mA collector current with 1 V Vce.
