It integrates two bias resistors — 47 kΩ base (R1) and 22 kΩ emitter-base (R2) — so a single GPIO pin can drive the base directly without external resistors. Collector current is rated 70 mA max, Vce breakdown at 50 V, and transition frequency hits 150 MHz, making it a fit for low-power switching and interface buffering in industrial and consumer boards. ## Last Buy — plan the BOM now Infineon has placed the BCR146E6327HTSA1 in Last Buy status. That means a final order window is open — once it closes, the part will no longer be manufactured. If this transistor is on your BOM, secure inventory or qualify a replacement before the LTB deadline passes. ## Switching and saturation — what the numbers mean Vce saturation is 300 mV at 500 µA base drive and 10 mA collector current — typical for a small-signal pre-biased transistor. DC current gain (hFE) minimum is 50 at 5 mA, 5 V. The 100 nA collector cutoff (ICBO) keeps leakage negligible in off-state. With a 200 mW power limit and SOT-23 footprint, thermal derating matters above a few tens of mA continuous; the part is sized for low-duty-cycle or lightly loaded outputs.","metaTitle":"BCR146E6327HTSA1 NPN Pre-Biased Transistor, 150 MHz, SOT-23","metaDescription":"Infineon BCR146E6327HTSA1 NPN pre-biased transistor, 50 V, 70 mA, 150 MHz, built-in 47k/22k resistors, PG-SOT23.","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":"200 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":"BCR146","Resistor - Base (R1)":"47 kOhms","Frequency - Transition":"150 MHz","Supplier Device Package":"PG-SOT23","Resistor - Emitter Base (R2)":"22 kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"70 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":"$0.3700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.infineon.com/dgdl/bcr146series.pdf?folderId=db3a30431400ef68011406f3ddb1012e&fileId=db3a30431428a373011440120c6802b7","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR146E6327HTSA1 obsolete?","answer":"Infineon has marked BCR146E6327HTSA1 as Last Buy, not fully obsolete.
