Description and Introduction

General Purpose Transistor (NPN Silicon) **Introducing the MMBT3904LT3G: A High-Performance NPN Transistor for Precision Applications**  

The MMBT3904LT3G is a high-performance NPN bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications. Known for its reliability and efficiency, this surface-mount transistor is an excellent choice for engineers working on compact, low-power circuits.  

With a maximum collector current of 200 mA and a collector-emitter voltage rating of 40 V, the MMBT3904LT3G provides robust performance in a variety of electronic designs. Its fast switching speed and low saturation voltage make it ideal for signal amplification, digital logic circuits, and interface applications. The device also features a high current gain (hFE), ensuring stable operation across a wide range of conditions.  

Housed in a compact SOT-23 package, the MMBT3904LT3G is optimized for space-constrained PCB layouts without compromising performance. Its lead-free and RoHS-compliant construction aligns with modern environmental standards, making it a sustainable choice for contemporary electronics.  

Engineers will appreciate the transistor’s consistent performance, even in demanding environments, thanks to its well-balanced electrical characteristics. Whether used in consumer electronics, industrial controls, or communication systems, the MMBT3904LT3G delivers precision and reliability.  

For designers seeking a dependable, high-quality NPN transistor, the MMBT3904LT3G stands out as a versatile and efficient solution. Its combination of performance, compact size, and durability makes it a preferred component for a wide range of electronic applications.

Application Scenarios & Design Considerations

General Purpose Transistor (NPN Silicon)

Alternative Part Number

  • 2N3904 --: Through-hole TO-92 NPN general-purpose transistor with nearly identical electrical characteristics; widely available and a classic drop-in for prototyping.
  • BC847B --: SOT-23 NPN transistor with comparable VCEO and current ratings, commonly used as a surface-mount substitute for the 3904 family.
  • PMBT3904 --: SOT-23 NPN switching transistor with essentially the same 3904 die specifications, offering a direct surface-mount alternative from a different series.
