The integrated 4.7 kOhms base resistor (R1) eliminates the external base resistor, saving board space and reducing component count in switching and driver applications. With a 500 mA maximum collector current and 50 V Vce breakdown, it suits low-to-medium current loads in industrial control, relay drivers, and logic-level interface circuits. The 100 MHz transition frequency supports moderate-speed switching up to a few megahertz. The 330 mW maximum power limit sets the thermal budget for this PG-SOT23 package. At 500 mA collector current, even a 300 mV Vce saturation drop dissipates 150 mW, leaving 180 mW headroom under the limit at 25 °C ambient. In a cramped board with limited copper area, derating is necessary — the junction-to-ambient thermal resistance of a SOT-23 on standard FR4 is typically around 300 °C/W, so the 330 mW ceiling corresponds to roughly a 100 °C junction rise above ambient. For continuous operation above 85 °C ambient, reduce the load current accordingly. ## Obsolete — sourcing path for the BOM Infineon lists the BCR 519 E6327 as obsolete. No official replacement order code is provided in the lifecycle record. For new designs, a pin-compatible pre-biased NPN in the same SOT-23 footprint should be selected after verifying base resistor value and current rating.","metaTitle":"BCR 519 E6327 NPN Pre-Biased Transistor, 500 mA, 50 V","metaDescription":"Infineon BCR 519 E6327 is an NPN pre-biased transistor in a PG-SOT23 package. 500 mA collector current, 50 V Vce breakdown, 100 MHz transition frequency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Power - Max":"330 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Obsolete","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR 519","Resistor - Base (R1)":"4.7 kOhms","Frequency - Transition":"100 MHz","Supplier Device Package":"PG-SOT23","Vce Saturation (Max) @ Ib, Ic":"300mV @ 2.5mA, 50mA","Current - Collector (Ic) (Max)":"500 mA","Current - Collector Cutoff (Max)":"100nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"120 @ 50mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2ce8d90a93823407d062b22ad262735f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the exact specifications of BCR 519 E6327?","answer":"The BCR 519 E6327 is an NPN pre-biased transistor with a 4.7 kOhms base resistor, 500 mA maximum collector current, 50 V Vce breakdown, 100 MHz transition frequency, 300 mV Vce saturation at 2.5 mA base and 50 mA collector, minimum DC current gain of 120 at 50 mA and 5 V, and a maximum collector cutoff current of 100 nA.
