It integrates a 10 kOhm base resistor (R1) and a 47 kOhm emitter-base resistor (R2), eliminating two external components on the board. The part is rated for 50 V collector-emitter breakdown, 100 mA continuous collector current, and 200 mW maximum power dissipation. With a transition frequency of 200 MHz, it handles switching applications well into the low-MHz range. Typical uses include inverter and interface circuits, relay and LED drivers, and general-purpose switching in consumer and industrial equipment where a single PNP switch with built-in bias is needed. ## Obsolete — sourcing through independent distribution The BCR185E6433HTMA1 carries an obsolete lifecycle status.","metaTitle":"BCR185E6433HTMA1 PNP Pre-Biased Transistor, 50 V, 100 mA","metaDescription":"Infineon BCR185E6433HTMA1 is a PNP pre-biased digital transistor in SOT-23. 50 V VCEO, 100 mA IC, 200 mW, 200 MHz fT.","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":"Not For New Designs","Transistor Type":"PNP - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR185","Resistor - Base (R1)":"10 kOhms","Frequency - Transition":"200 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":"$0.0474","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/66701357389c2165763e8a31e7820059.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BCR185E6433HTMA1?","answer":"Infineon has not published an official successor order code for the BCR185E6433HTMA1.
