That resistor network eliminates two external passives per channel on the board, which matters when you are packing multiple low-side switches into a tight layout. Rated for 50 V collector-emitter breakdown and 500 mA continuous collector current, it handles general-purpose switching in loads like relays, solenoids, small motors, and indicator LEDs. The 150 MHz transition frequency keeps switching losses low for PWM up to a few hundred kilohertz. Infineon has marked the BCR573E6327HTSA1 as Last Buy. That means the manufacturer is taking final orders before the part is discontinued — there is a finite window to secure production quantities or to qualify a drop-in replacement. For a BOM that already uses this part, the procurement action is to assess remaining lifetime demand and place a last-time buy, or to begin evaluating a pin-compatible pre-biased PNP from the same or another supplier. ## Sourcing reality — quoted to order Because the BCR573E6327HTSA1 is in Last Buy, standard distributor stock may be limited or already depleted. If you have a BOM line that needs filling, send the quantity and target date-code window and we will check the open market.","metaTitle":"Infineon BCR573E6327HTSA1 PNP Pre-Biased Transistor, 50 V","metaDescription":"Infineon BCR573E6327HTSA1 PNP pre-biased digital transistor in SOT-23. 50 V VCEO, 500 mA Ic, 1 kΩ base / 10 kΩ emitter-base resistors.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Power - Max":"330 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Last Time Buy","Transistor Type":"PNP - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR573","Resistor - Base (R1)":"1 kOhms","Frequency - Transition":"150 MHz","Supplier Device Package":"PG-SOT23","Resistor - Emitter Base (R2)":"10 kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 2.5mA, 50mA","Current - Collector (Ic) (Max)":"500 mA","Current - Collector Cutoff (Max)":"100nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"70 @ 50mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.0736","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.infineon.com/dgdl/bcr573.pdf?folderId=db3a30431428a373011440769fd70304&fileId=db3a30431428a373011440841409030e","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy BCR573E6327HTSA1?","answer":"The BCR573E6327HTSA1 is in Last Buy status."},{"question":"What is the equivalent of BCR573E6327HTSA1?","answer":"The BCR573 base number covers the pre-biased PNP family. A pin-compatible alternative would be another pre-biased PNP in SOT-23 with the same resistor values (R1 = 1 kΩ, R2 = 10 kΩ) and similar voltage/current ratings. Check Infineon's own BCR573 series siblings or cross-reference with a supplier like Nexperia or Rohm for a direct substitute."},{"question":"Can I use BCR573E6327HTSA1 to replace a standard PNP transistor?","answer":"Yes, but only in circuits designed for the integrated bias resistors. The 1 kΩ base resistor and 10 kΩ emitter-base resistor are fixed — you cannot change the base drive. If your circuit expects an external base resistor or a different bias network, a standard PNP without internal resistors is the correct choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR573E6327HTSA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR573E6327HTSA1 when reusing this data.
