It integrates a 22 kOhm base resistor (R1) and a 47 kOhm emitter-base resistor (R2), eliminating the need for external bias components in low-current switching and driver applications. Rated for 100 mA collector current and 50 V collector-emitter breakdown, it suits relay drivers, LED switches, and logic-level interface circuits where board space is at a premium. ## Built-in resistors simplify the BOM The DC current gain (hFE) is a minimum of 70 at 5 mA, 5 V, which means a 100 µA base current from the logic pin can saturate the transistor with 10 mA of collector load. The 300 mV Vce saturation at 500 µA base, 10 mA collector confirms low on-state voltage drop for efficient switching. ## Switching speed and leakage Transition frequency is 150 MHz. Collector cutoff current is 100 nA maximum. ## Active and available to source No direct pin-compatible replacement is listed, but the BCR 142 family includes other pre-biased NPN variants in different resistor ratios or packages — verify the resistor values match your drive requirements before substituting.","metaTitle":"Infineon BCR 142T E6327 NPN Pre-Biased Transistor, 100 mA","metaDescription":"Infineon BCR 142T E6327 NPN pre-biased transistor, 100 mA Ic, 50 V Vce, 150 MHz fT, built-in 22 kΩ / 47 kΩ resistors, SC-75 SMD package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Power - Max":"250 mW","Mounting Type":"Surface Mount","Package / Case":"SC-75, SOT-416","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR 142","Resistor - Base (R1)":"22 kOhms","Frequency - Transition":"150 MHz","Supplier Device Package":"PG-SC-75","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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/360648298a8dc3d85c4fd17e8e02823d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the collector current rating of BCR 142T E6327?","answer":"The maximum collector current (Ic) is 100 mA.
