Overview of FMMT489TA

The FMMT489TA is a versatile small-signal BJT that is well-suited for a variety of switching and amplification applications. With a maximum collector current of 1.5A and a peak current of 3A, this PNP transistor offers reliable performance in a compact SOT-23 package, making it ideal for space-constrained electronic designs. Its maximum collector-emitter voltage rating of 50V and a DC current gain (hfe) of 250 ensure stable operation in a range of scenarios, while the low saturation voltage of 0.3V at a collector current of 1A makes it an excellent choice for low-power dissipation applications
