It integrates two bias resistors — a 4.7 kΩ base resistor (R1) and a 47 kΩ emitter-base resistor (R2) — so you can drive it directly from a microcontroller GPIO without adding external resistors. The collector-emitter breakdown is rated at 50 V, and continuous collector current is 100 mA, with a total power dissipation ceiling of 250 mW. Typical applications include low-current relay drivers, LED switching, and level shifting in 5 V or 12 V logic systems. ## Bias resistors save board space With R1 = 4.7 kΩ and R2 = 47 kΩ already on-chip, the BCR116 eliminates two external passives per channel. That matters when you are packing multiple switching stages into a tight layout — the SC-70 footprint is about 2.0 mm × 1.25 mm, and every resistor you remove frees up real estate. The pre-biased topology also guarantees a consistent base drive regardless of the GPIO voltage, as long as the input stays within the transistor's safe operating area. ## NRND — plan the transition now That means it is still available for existing production runs, but the manufacturer intends to phase it out.","metaTitle":"Infineon BCR116WH6327XTSA1 NPN Pre-Biased Transistor, 50 V","metaDescription":"Infineon BCR116WH6327XTSA1 NPN pre-biased transistor, 50 V VCEO, 100 mA Ic, 250 mW max.

The BCR116 family includes several variants with different R1/R2 ratios (e.g., 10 kΩ / 10 kΩ, 22 kΩ / 22 kΩ) that share the same SC-70 footprint. Check the BCR116 series datasheet for a resistor combination that matches your drive current requirements."},{"question":"Can I use BCR116WH6327XTSA1 in a 5V circuit?","answer":"Yes. The collector-emitter breakdown is 50 V, so 5 V logic is well within the safe operating area. The built-in 4.7 kΩ base resistor limits base current from a 5 V GPIO to roughly 1 mA, which is enough to saturate the transistor at collector currents up to 100 mA. The 47 kΩ emitter-base resistor ensures the transistor turns off cleanly when the GPIO goes low."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR116WH6327XTSA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR116WH6327XTSA1 when reusing this data.
