DIOFZT705TA
Overview
The FZT705TA is a high-performance PNP Darlington transistor housed in a SOT-223 surface mount package. It is designed to handle a continuous collector current of 2A and provides a high breakdown voltage of 120V, making it suitable for medium-power switching applications. The Darlington configuration ensures high current gain, allowing the device to be driven directly by low-power integrated circuits or microcontrollers.
Why Choose This Part
With a transition frequency of 160MHz and a high gain-bandwidth product, this device offers faster switching speeds than many standard Darlington transistors. Its SOT-223 package provides excellent thermal performance, supporting a power dissipation of up to 2W in a compact footprint.

Key Specifications
Getting Started
When integrating this PNP Darlington, ensure sufficient copper area is provided on the PCB collector pad for heat sinking to achieve the 2W power rating. Use a base resistor to limit input current, keeping in mind the 2.5V Vce saturation voltage at 2A when calculating thermal losses.
