Each transistor includes built-in bias resistors — 47 kΩ base (R1) on both sides, plus a 47 kΩ emitter-base resistor (R2) on the NPN — so you save board space and eliminate up to four external resistors per channel. This is a common building block for low-power switching, level shifting, and driver stages where the load current stays under 70 mA (NPN) or 100 mA (PNP) and the collector-emitter voltage never exceeds 50 V. ## Obsolete — what that means for procurement Infineon lists the BCR48PNE6433BTMA1 as obsolete. The only supply path is the surplus and independent distribution market — sealed factory reels, mixed date-code lots, or customer inventory resale. For a BOM line that depends on this exact order code, the procurement decision is straightforward: qualify a surplus lot against the original spec and order what the market holds, or plan a redesign around a current-production equivalent. ## Key ratings — what they mean for fit The 50 V collector-emitter breakdown sets the rail voltage ceiling. The 250 mW package dissipation limits continuous current; at 5 V rail and 70 mA on the NPN side, derating is necessary. The 300 mV saturation at 500 µA base / 10 mA collector is typical for a pre-biased part. The 100 MHz / 200 MHz transition frequencies are adequate for switching up to a few megahertz.","metaTitle":"BCR48PNE6433BTMA1 Infineon Dual Pre-Biased Transistor, 50V","metaDescription":"Infineon BCR48PNE6433BTMA1 dual NPN/PNP pre-biased transistor. 50V VCEO, 70/100mA Ic, 250mW, 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":"1 NPN, 1 PNP - Pre-Biased (Dual)","lifecycle_stage":"eol_hot","Base Product Number":"BCR48PN","Resistor - Base (R1)":"47kOhms, 2.2kOhms","Frequency - Transition":"100MHz, 200MHz","Supplier Device Package":"PG-SOT363-PO","Resistor - Emitter Base (R2)":"47kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"70mA, 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/61cef50cc2758f0381116840d381739a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy BCR48PNE6433BTMA1?","answer":"Submit an RFQ for current availability and pricing — we confirm both at quote time from our surplus and broker network."},{"question":"Is BCR48PNE6433BTMA1 obsolete?","answer":"Yes, Infineon lists the BCR48PNE6433BTMA1 as obsolete.
