It integrates a 47 kΩ base resistor (R1) and a 22 kΩ emitter-base resistor (R2), eliminating two external passives from the BOM. Rated for a collector-emitter breakdown of 50 V and a continuous collector current of 70 mA, it suits low-current switching, relay and solenoid drivers, and logic-level interface circuits in 12 V and 24 V automotive systems. ## Integrated resistors simplify the BOM The built-in bias network means the transistor is fully on with a logic-high drive — no external base resistor to size. The 47 kΩ base resistor sets a predictable base current for a given input voltage, while the 22 kΩ emitter-base resistor provides a bleed path to ensure fast turn-off and improve noise immunity. This makes the part a drop-in replacement for discrete transistor-plus-resistor pairs in space-constrained layouts. ## Switching performance and saturation With a transition frequency of 150 MHz, the BCR146E6327 handles low-frequency PWM and digital switching well into the hundreds of kilohertz. Saturation voltage is specified at 300 mV maximum at a base current of 500 µA and collector current of 10 mA, keeping conduction losses low in saturated switching. Minimum DC current gain of 50 at 5 mA, 5 V ensures consistent drive capability across temperature. ## Automotive qualification and temperature range The BCR146E6327 carries AEC-Q101 qualification, meaning it has passed the automotive stress tests for reliability — including high-temperature reverse bias, temperature cycling, and humidity. This makes it suitable for under-hood and cabin electronics where extended temperature range and long service life are required.","metaTitle":"BCR146E6327 NPN Pre-Biased Transistor, 50 V, 70 mA, SOT-23-3","metaDescription":"Infineon BCR146E6327 automotive AEC-Q101 NPN pre-biased transistor, 50 V Vce, 70 mA Ic, 150 MHz ft, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"Automotive, AEC-Q101","Package":"Bulk","Power - Max":"200 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Resistor - Base (R1)":"47 kOhms","Frequency - Transition":"150 MHz","Supplier Device Package":"PG-SOT23-3-3","Resistor - Emitter Base (R2)":"22 kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"70 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":"$0.0300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2c251d99825923f443ba83dcbba01223.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can BCR146E6327 replace a DTA124EKA?","answer":"The DTA124EKA is a PNP pre-biased transistor, while the BCR146E6327 is NPN.
