It integrates the base bias resistor (R1 = 2.2 kOhms) and a resistor from emitter to base (R2 = 47 kOhms), eliminating two external components per switching node. ## Ratings that define the switching budget Collector current is rated 100 mA maximum, with a collector-emitter breakdown voltage of 50 V — enough for most 12 V and 24 V industrial logic interfaces. The 170 MHz transition frequency means it handles switching up to a few tens of MHz cleanly, though the integrated resistors limit the edge rate compared to a bare transistor. Saturation voltage is specified at 300 mV at 500 µA base current and 10 mA collector current — the pre-bias ratio (R1 / R2 ≈ 0.047) keeps the transistor in saturation with a modest input drive. DC current gain minimum of 70 at 5 mA, 5 V confirms it saturates reliably in the low-current regime. ## NRND — not for new designs Infineon has not announced a direct successor in the BCR108 base product number family, so existing production slots or surplus stock are the sourcing channels. For a BOM line that is still in qualification, this part is still obtainable through independent distribution against an RFQ — but a new design should select a current-production pre-biased NPN in the same SC-70 footprint.","metaTitle":"Infineon BCR108WH6433XTMA1 NPN Pre-Biased Transistor","metaDescription":"Infineon BCR108WH6433XTMA1 NPN pre-biased transistor in SC-70 (SOT-323) package. 100 mA Ic, 50 V VCEO, 170 MHz fT, 250 mW.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","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":"BCR108","Resistor - Base (R1)":"2.2 kOhms","Frequency - Transition":"170 MHz","Supplier Device Package":"PG-SOT323","Resistor - Emitter Base (R2)":"47 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":"70 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.0506","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7495c3884ac1e791d30a362fa78f30ce.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR108WH6433XTMA1 obsolete or NRND?","answer":"It is not fully discontinued, but Infineon advises against using it in new product designs.
