PCB transistor parts for power electronics applications generally include a die-attached metal paddle that can also function as a ground pin.

Other components that are specialized for specific applications are BJT and FET components in surface mount packages, such as the SOT package or even QFN packages. Perhaps the most common discrete transistor for use in analog signaling and power electronics systems is the through-hole MOSFET or similar high-voltage/high-current components. PCB transistors come in a variety of through-hole and surface-mount packages. Understanding PCB Transistor Footprints and Packages When electronic parts search features are accessible alongside standard ECAD tools, a design team can stay productive and access the parts data they need for defect-free manufacturing. The best way to access the supply chain and an accurate PCB footprint transistor is to work in Altium Designer’s integrated design environment. To keep yields high, designers need a complete set of PCB supply chain tools that give them CAD data for transistor parts used in a PCB layout. Designers should be aware of footprint transistor requirements for parts to ensure proper fabrication and solderability during assembly. Every part that gets placed on a PCB needs to have an important set of information to enable front-end design and back-end manufacturability. The industry’s only EDA application that gives designers access to a huge range of transistor parts, supply chain tools, and the industry’s best PCB design features.Įven though CPUs contain billions of transistor footprints, many PCBs still need discrete transistors to operate properly. When you’re designing systems with discrete transistors, use the best PCB supply chain tools in Altium Designer. Altium Designer includes the complete set of PCB supply chain features you need to find transistor parts, including footprints and specifications for discrete transistor footprints. When you use the complete set of PCB design tools in Altium Designer, you can do more than just place existing PCB transistor footprints in your PCB. When you need to find and place transistors in your new design, you need a complete set of PCB supply chain tools for finding transistor parts for your design. Many power electronics products, sensors, low-power analog systems, and other systems requiring high-power switching need transistors to operate properly. Transistors are fundamental devices for everything from power supplies to high-power integrated circuits for embedded computing.
