FMMTL618TA DIODES Single

The FMMTL618TA from Diodes Incorporated is a NPN bipolar transistor optimized for low-saturation switching and small-signal amplification in space-constrained designs. With a continuous collector current of 1.25A and a low Vce(sat) of just 350mV at 200mA, it delivers efficient power control with minimal voltage drop, making it ideal for driving relays, LEDs, small motors, and solenoids in consumer electronics and portable devices. Its 195MHz transition frequency and DC current gain of 250 ensure stable amplification for audio preamps, sensor interfaces, and low-frequency communication circuits. Housed in an industry-standard SOT-23-3 surface-mount package, it also serves effectively in overcurrent protection, load switching, and simple power management circuits where board space and thermal performance are critical. Operating from -55°C to +150°C with 500mW dissipation, this RoHS-compliant transistor provides a reliable, cost-effective solution for general-purpose switching and linear applications.
