This eliminates two external passives from the board, saving placement cost and PCB area in simple switching applications like relay drivers, LED indicators, or logic-level interface circuits. ## 50 V breakdown, 100 mA collector — typical low-side switch The 300 mV saturation voltage at 10 mA collector current and 500 µA base drive means it switches cleanly into saturation with minimal dissipation in the on-state. ## Sourcing an obsolete part — what to expect Infineon lists the BCR148E6433HTMA1 as Obsolete.","metaTitle":"BCR148E6433HTMA1 Infineon NPN Pre-Biased Transistor, 50 V","metaDescription":"Infineon BCR148E6433HTMA1 NPN pre-biased transistor, 50 V VCEO, 100 mA IC, 47 kΩ resistors, SOT-23, obsolete.","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":"200 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":"BCR148","Resistor - Base (R1)":"47 kOhms","Frequency - Transition":"100 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":"$0.1300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/48b524a21f70ba87148fe966031e06a7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BCR148E6433HTMA1/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for BCR148E6433HTMA1?","answer":"Infineon has not published a direct successor order code for the BCR148E6433HTMA1.
