Rated for 500 mA continuous collector current and 50 V collector-emitter breakdown, it handles low-side switching and driver loads in industrial and consumer gear where board space is tight. ## 330 mW power limit — derating in the SOT-23 footprint Maximum power dissipation is 330 mW in the PG-SOT23 package — the limiting factor is the copper pad area under the transistor, not the silicon. At 500 mA the Vce(sat) is 300 mV typical at 2.5 mA base drive, so conduction loss stays under 150 mW in saturation. Transition frequency is 100 MHz, adequate for switching up to a few MHz in relay drivers, solenoid coils, and logic-level translators. ## Last Buy — plan the LTB quantity now Infineon lists the BCR533E6327HTSA1 as Last Buy — the final order window is open, and once it closes the part moves to end-of-life with no factory replenishment. For a BOM that needs this pre-biased NPN, the LTB quantity should cover the remaining production run plus a service-spare buffer.","metaTitle":"BCR533E6327HTSA1 NPN Pre-Biased Transistor, 500 mA, 50 V","metaDescription":"Infineon BCR533E6327HTSA1 NPN pre-biased transistor, 500 mA Ic, 50 V Vce, 330 mW, SOT-23-3.","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":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR533","Resistor - Base (R1)":"10 kOhms","Frequency - Transition":"100 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":"$0.4800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e889f8fb7ff2c1b43bf13e9b8e8c89c1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR533E6327HTSA1 obsolete or end of life?","answer":"Infineon has classified the BCR533E6327HTSA1 as Last Buy.
