High-Gain, Low-Power NPN/PNP Transistors in SOT-23-3L Package for Compact Circuit Designs
The SOT-23-3L series small signal transistors offer standard 3-lead surface-mount packages, ideal for high-density PCB layouts. This family includes NPN and PNP single bipolar junction transistors, with collector current up to 2000mA (e.g., FMMT619L), maximum breakdown voltages up to ±60V, and gain (H<sub>FE</sub>) reaching 800. Available in multiple grading levels (Q/R/S/E/F/G), these transistors are ideal for signal amplification, level shifting, switching, and general-purpose logic applications.
