This built-in bias network eliminates two external resistors per channel, saving board area in high-density designs like relay drivers, logic-level translators, and low-current load switches. The transition frequency of 150 MHz is adequate for switching up to several megahertz. Date-code provenance and condition should be confirmed at quote time, especially for stock surfacing well after the last-time-buy window. The built-in 4.7 kΩ base resistor sets the base current for a given drive voltage — at 3.3 V logic, base current is roughly (3.3 V – 0.7 V) / 4.7 kΩ ≈ 550 µA, which with a minimum DC current gain of 70 at 5 mA collector current gives plenty of drive headroom for switching a 10 mA load. The 47 kΩ emitter-base resistor ensures the transistor is held off when the base drive is open or high-impedance, which is useful in mixed-voltage or power-sequencing applications. Vce(sat) of 300 mV max at 10 mA collector current keeps conduction losses low in saturated switching. The 250 mW power dissipation limit in the SOT-323 package means derating is needed above about 85 °C ambient if running near the full 100 mA.","metaTitle":"BCR116WE6327BTSA1 NPN Pre-Biased Transistor, 50 V, 100 mA","metaDescription":"Infineon BCR116WE6327BTSA1 NPN pre-biased transistor in SOT-323. 50 V, 100 mA, built-in 4.7 kΩ base resistor, 150 MHz transition frequency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR116","Resistor - Base (R1)":"4.7 kOhms","Frequency - Transition":"150 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":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BCR116WE6327BTSA1/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for BCR116WE6327BTSA1?","answer":"No official replacement has been published by Infineon. A functionally equivalent pre-biased NPN in SOT-323 with the same 4.7 kΩ base and 47 kΩ emitter-base resistor values would be the closest substitute — confirm pin compatibility and electrical ratings before substituting."},{"question":"What is the difference between BCR116 and BCR119?","answer":"The BCR119 is also a pre-biased NPN in SOT-323 but uses different resistor values: typically 10 kΩ for the base resistor and 47 kΩ for the emitter-base resistor. The BCR116 uses 4.7 kΩ and 47 kΩ respectively, so the base drive current at a given logic voltage will differ — the BCR116 pulls more base current for a given input voltage, which can matter in low-drive or high-noise environments."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR116WE6327BTSA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR116WE6327BTSA1 when reusing this data.
