Overview
The Diodes Incorporated FMMT718TA is a high-performance PNP bipolar junction transistor (BJT) designed for demanding switching and amplification tasks. Its key strength lies in its robust current handling capability of up to 1.5A, coupled with a low Vce(sat) of 145mV at 2A, making it efficient for power management. A critical design consideration is the trade-off between its high gain (hFE up to 300) at lower currents and its reduced gain at peak current demands, requiring careful biasing to maintain linearity in analog applications or ensure reliable switching transitions in digital circuits.
Key Features
- Collector-Emitter Voltage (VCEO): 20 V
- Continuous Collector Current (IC): 1.5 A
- Power Dissipation (Pd): 625 mW
- Gain Bandwidth Product (fT): 180 MHz
- Collector-Emitter Saturation Voltage (Vce(sat)): 145 mV @ 2A
- Package: SOT-23-3 (3.05mm x 1.4mm x 1mm)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Low-side load switching in battery-powered portable devices
- High-efficiency DC-DC converter pre-regulation stages
- Signal driver for medium-power LEDs and small motors
- Analog signal gain stages in audio preamplifiers
