The MMBT5551 with Transistors (NPN/PNP) SOT-23-3 RoHS is a low-cost transistor manufactured by Youtai. It is a dual-sided NPN/PNP small outline transistor, or SOT-23-3, which measures just 2.9 x 1.3 x 0.95mm in size. This RoHS compliant device is well suited for use in digital and linear applications. The MMBT5551 offers excellent electrical characteristics such as low saturation voltage, high gain, and high switching speed for its size. It also features low base-emitter voltage and low collector-base leakage current, making it a reliable option for use in high-frequency, low-power electronic devices.
