It handles a continuous collector current up to 500 mA with a collector-emitter breakdown voltage of 50 V, and a transition frequency of 100 MHz. This part is designed for switching and interface applications where the built-in bias resistors eliminate the need for external base and emitter resistors, shrinking the BOM and board area. ## Obsolete — plan your BOM move now Infineon lists the BCR 512 B6327 as obsolete. If you are managing a legacy BOM line, now is the time to evaluate a replacement or secure a last-time-buy quantity. ## Saturation voltage and gain — what matters for the switch The Vce(sat) is specified at 300 mV maximum with a base current of 2.5 mA and collector current of 50 mA — a typical operating point for logic-level drive. The DC current gain (hFE) is a minimum of 60 at 50 mA and 5 V Vce, giving you a solid drive margin. The 100 nA maximum collector cutoff current (ICBO) ensures low leakage in off-state, important for battery-powered or high-impedance circuits.","metaTitle":"BCR 512 B6327 NPN Pre-Biased Transistor, 500 mA, 50 V","metaDescription":"BCR 512 B6327 NPN pre-biased transistor, 500 mA collector current, 50 V breakdown, 330 mW, SOT-23-3.","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 512","Resistor - Base (R1)":"4.7 kOhms","Frequency - Transition":"100 MHz","Supplier Device Package":"PG-SOT23","Resistor - Emitter Base (R2)":"4.7 kOhms","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":"60 @ 50mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8b4949fc3275c1867dcd49982212015a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BCR 512 B6327?","answer":"Infineon does not list a direct successor for the BCR 512 B6327.
