It integrates a 4.7 kOhm base resistor (R1) and a 4.7 kOhm emitter-base resistor (R2) on-chip, eliminating two external passives from the board. Collector-emitter breakdown is rated 50 V, continuous collector current 100 mA, and the package dissipates up to 250 mW. Transition frequency is 140 MHz, and saturation voltage is 300 mV at 500 µA base drive with 10 mA collector current. ## Last Buy — final procurement window is open Infineon has classified the BCR112WH6327XTSA1 as Last Buy, meaning the manufacturer has announced end-of-life and this is the final production run. Buyers should secure lifetime or bridge-buy quantities now; after the last-time-buy window closes, supply will shift to independent-distribution surplus only. ## Package and mounting With both R1 and R2 at 4.7 kOhms, this transistor is configured for a fixed base-drive ratio. The pre-biased design sets the on/off threshold and guarantees the transistor is fully off when the input is low, without an external base resistor. It reflows cleanly with a standard lead-free profile; just watch the 250 mW dissipation limit if you're running it near 100 mA continuous in a tight layout.","metaTitle":"Infineon BCR112WH6327XTSA1 NPN Pre-Biased Transistor, 50 V","metaDescription":"Infineon BCR112WH6327XTSA1 NPN pre-biased transistor in SC-70 (SOT-323). 50 V VCEO, 100 mA IC, 250 mW max. 4.7 kOhm base and emitter 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)","Power - Max":"250 mW","Mounting Type":"Surface Mount","Package / Case":"SC-70, SOT-323","Product Status":"Not For New Designs","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR112","Resistor - Base (R1)":"4.7 kOhms","Frequency - Transition":"140 MHz","Supplier Device Package":"PG-SOT323","Resistor - Emitter Base (R2)":"4.7 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":"20 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.0501","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.infineon.com/dgdl/bcr112series.pdf?folderId=db3a30431400ef68011406f3ddb1012e&fileId=db3a30431428a37301143a34902e01d0","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR112WH6327XTSA1 obsolete or still available for purchase?","answer":"Infineon has marked the BCR112WH6327XTSA1 as Last Buy.
