This means the base and emitter bias network is already on-chip, so you drop the two external resistors from the BOM. It is rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, with a transition frequency of 130 MHz. Typical use: switching loads in 5 V or 12 V logic-level circuits, relay and solenoid drivers, or as an inverter in industrial control I/O. The SOT-323 (SC-70) footprint is small enough for dense boards and easy to hand-place if needed. ## 50 V breakdown, 100 mA Ic — what the ratings mean on site The 50 V VCEO gives you a solid safety margin on 24 V industrial supplies — no need to derate for transients unless you are seeing spikes above 60 V. The 100 mA collector current handles small relays, LEDs, and optocoupler inputs without breaking a sweat. Saturation voltage is 300 mV at 500 µA base and 10 mA collector, so the transistor stays cool in low-duty-cycle switching. Infineon lists the BCR141WH6327 as Active (current product status). No single-source risk; the pre-biased transistor family has multiple density options if you need to adjust the resistor ratio.","metaTitle":"Infineon BCR141WH6327 NPN Pre-Biased Transistor, 50 V","metaDescription":"Infineon BCR141WH6327 NPN pre-biased transistor in SC-70/SOT-323. 50 V VCEO, 100 mA Ic, 130 MHz fT, built-in 22 kΩ resistors.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Bulk","Power - Max":"250 mW","Mounting Type":"Surface Mount","Package / Case":"SC-70, SOT-323","Product Status":"Active","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Resistor - Base (R1)":"22 kOhms","Frequency - Transition":"130 MHz","Supplier Device Package":"PG-SOT323-3-1","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bceb8f6c0f9e9220cd52cade55a1ef6b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does BCR141WH6327 have built-in bias resistors?","answer":"Yes — it integrates a 22 kΩ base resistor (R1) and a 22 kΩ emitter-base resistor (R2), so no external bias network is needed."},{"question":"What is a good replacement or equivalent for BCR141WH6327?","answer":"Within the same Infineon pre-biased NPN family, the BCR135WH6327 is a common cross-shop candidate — it uses different internal resistor values (10 kΩ R1 / 10 kΩ R2 versus the BCR141's 22 kΩ / 22 kΩ), so the turn-on threshold and base drive differ.
