This eliminates two external passives per switching node, shrinking the PCB footprint and reducing pick-and-place cost. Rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, it suits low-side switching in 5 V to 24 V logic-level loads — relay coils, indicator LEDs, small solenoids. ## Last Buy — plan your final order Infineon has placed the BCR141E6327HTSA1 in Last Buy status. This means the manufacturer has announced end-of-life; remaining production windows and distributor inventory are finite. Once the last-time-buy window closes, the part will no longer be manufactured. For production lines that already qualify this transistor, securing a final lot against the BOM quantity is the immediate priority. ## SOT-23 footprint and thermal budget Packaged in a standard SOT-23-3 (PG-SOT23), the device lands on a 0.95 mm pin pitch footprint common across small-signal transistors. Maximum power dissipation is 250 mW; the thermal limit is set by the copper pad area on the PCB, not the package itself.","metaTitle":"BCR141E6327HTSA1 NPN Pre-Biased Transistor, 50V, 100mA","metaDescription":"BCR141E6327HTSA1 NPN pre-biased transistor, 50 V Vce, 100 mA Ic, 22 kOhm base and emitter resistors, 130 MHz ft, SOT-23.","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":"250 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Not For New Designs","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR141","Resistor - Base (R1)":"22 kOhms","Frequency - Transition":"130 MHz","Supplier Device Package":"PG-SOT23","Resistor - Emitter Base (R2)":"22 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":"50 @ 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/4a143be0858abe3a797ba5cb60ada74a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BCR141E6327HTSA1?","answer":"For a pin-compatible pre-biased NPN in SOT-23, check the BCR141 series base number (BCR141) — other variants may differ in resistor values or package suffix.
