It integrates a 22 kΩ base resistor (R1) and a 47 kΩ emitter-base resistor (R2), eliminating two discrete passives from the BOM and shrinking the layout. Collector-emitter breakdown is rated at 50 V, continuous collector current at 100 mA, and transition frequency at 150 MHz — a general-purpose switching transistor for low-power loads up to 200 mW. ## Last Buy — plan the BOM transition now Infineon has placed the BCR142E6327HTSA1 into Last Buy status, meaning final production orders are being accepted for a limited window. After that, the part will be discontinued. For new designs or long-running production, identify a pin-compatible pre-biased NPN in the same SOT-23 footprint with matching resistor values — several Infineon BCR series parts share the pinout. For existing BOMs, the surplus and broker channel remains the supply path once the LTB window closes. The 22 kΩ base resistor sets the turn-on threshold: with a 5 V logic signal, base current sits around (5 V − 0.7 V) / 22 kΩ ≈ 195 µA, enough to saturate the transistor with Ic up to 10 mA. The 47 kΩ emitter-base resistor provides a hard pull-down when the drive is off, keeping leakage below 100 nA. Vce(sat) is 300 mV at 500 µA base drive and 10 mA collector current — low enough for logic-level switching without excessive dissipation. The 150 MHz fT means it handles PWM into the low-MHz range cleanly.","metaTitle":"Infineon BCR142E6327HTSA1 NPN Pre-Biased Transistor, 50V","metaDescription":"Infineon BCR142E6327HTSA1 NPN pre-biased transistor in SOT-23, 50V Vce, 100mA Ic, 150MHz fT.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"-","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Part Status":"Last Time Buy","Power - Max":"200 mW","Manufacturer":"Infineon Technologies","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR142","Resistor - Base (R1)":"22 kOhms","Frequency - Transition":"150 MHz","Supplier Device Package":"PG-SOT23","Resistor - Emitter Base (R2)":"47 kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"100 mA","Current - Collector Cutoff (Max)":"100nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"70 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/15916323a0294a8799b1bb4314e88a75.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BCR142E6327HTSA1?","answer":"Infineon does not list a direct official replacement. For a pin-compatible pre-biased NPN in SOT-23 with similar resistor values, look at other Infineon BCR series parts or a broad portfolio from Nexperia or Rohm. Confirm the resistor divider ratio (R1/R2) and Vce/Ic ratings match your application."},{"question":"Is BCR142E6327HTSA1 compatible with 5V logic?","answer":"Yes. With a 22 kΩ base resistor, a 5 V logic high delivers roughly 195 µA base current, which saturates the transistor for collector currents up to 10 mA.
