TO-220 Transistor Package - Standard Power Semiconductor Component #294057 (License: Personal Use)

This image depicts a stylized black silhouette of a TO-220 transistor package, featuring a rectangular body with a metal tab for heat dissipation and three protruding leads for electrical connections. The circular marking on the top indicates pin 1 orientation, critical for correct circuit assembly. It represents a standard form factor for medium-to-high power transistors, MOSFETs, and voltage regulators.

Used on electronics component datasheets, educational resources, PCB design guides, and e-commerce product pages to visually identify the TO-220 package type; matches user intent for identifying, selecting, or learning about power semiconductor packaging.
