The FMMT589 is a NPN/PNP small outline transistor (SOT-23) designed and manufactured by Shikues, a leading electronic components manufacturer. This RoHs compliant transistor is designed for power and switching electronic applications, and is suitable for use in low-power supplies, switching and driver stages, and digital circuits. The in-built protection circuit prevents accidental forward-bias and heat dissipation, enabling the device to handle heavy and inductive loads. This device features high speed switching capability, excellent thermal stability, and low power consumption making it suitable for a wide range of electronic applications. It also provides efficient performance with minimal harmonic distortion and low voltage droop. The package is small and allows for easy and convenient hand-soldering.
