Infineon lists the BCR148SE6433HTMA1 as obsolete. The 50 V VCEO gives you comfortable headroom for 12 V, 24 V, and most 48 V industrial rails. The 100 mA Ic per transistor handles small relays, LEDs, and logic-level loads. With hFE minimum 70 at 5 mA and Vce(sat) of 300 mV at 10 mA, the part switches cleanly without wasting much voltage across the collector-emitter junction. The 250 mW total power limit means you need to watch the thermal budget if both transistors run near full current simultaneously.","metaTitle":"BCR148SE6433HTMA1 dual NPN pre-biased transistor, 50 V","metaDescription":"Infineon BCR148SE6433HTMA1 dual NPN pre-biased transistor, 50 V VCEO, 100 mA Ic, 250 mW, SOT-363.","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":"250mW","Mounting Type":"Surface Mount","Package / Case":"6-VSSOP, SC-88, SOT-363","Product Status":"Obsolete","Transistor Type":"2 NPN - Pre-Biased (Dual)","lifecycle_stage":"eol_hot","Base Product Number":"BCR148S","Resistor - Base (R1)":"47kOhms","Frequency - Transition":"100MHz","Supplier Device Package":"PG-SOT363-PO","Resistor - Emitter Base (R2)":"47kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"100mA","Current - Collector Cutoff (Max)":"-","DC Current Gain (hFE) (Min) @ Ic, Vce":"70 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/48b524a21f70ba87148fe966031e06a7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BCR148SE6433HTMA1/alternatives.json"},"ai":{"faq":[{"question":"What is a replacement for BCR148S?","answer":"Infineon has not published an official successor for the BCR148S.
