The 170 MHz transition frequency supports moderate-speed switching up to a few tens of megahertz. ## Last-time-buy — plan the BOM transition Buyers should secure final lifetime quantities or qualify a replacement before the last order window closes. The base product number is BC817; the suffix denotes the hFE grouping and the package variant. ## Package and thermal — PG-SOT23 layout notes The PG-SOT23 package (TO-236-3 / SC-59 / SOT-23-3) is a standard three-lead surface-mount footprint. Maximum power dissipation is 500 mW; at 150°C junction temperature, derating is necessary above 25°C ambient. For continuous operation near 500 mA, ensure adequate copper area on the collector pad to spread heat. The 100 nA maximum collector cutoff current (ICBO) confirms low leakage at room temperature, but expect an order-of-magnitude increase at 150°C junction.","metaTitle":"BC817K16E6327HTSA1 NPN Transistor, 45 V, 500 mA, PG-SOT23","metaDescription":"Infineon BC817K16E6327HTSA1 NPN transistor: 45 V Vce, 500 mA Ic, hFE 100 at 100 mA, 170 MHz fT, PG-SOT23.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Power - Max":"500 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Last Time Buy","Transistor Type":"NPN","lifecycle_stage":"eol_hot","Base Product Number":"BC817","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":"$0.3600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e1198b7a398bf9fcc31ab9c515acedbd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BC817K16E6327HTSA1/alternatives.json"},"ai":{"faq":[{"question":"Is BC817K16E6327HTSA1 obsolete or still available?","answer":"BC817K16E6327HTSA1 is in Last Buy status, meaning production is ending.
