TO-220 Transistor Component - High-Power NPN/PNP Semiconductor Device #3874913 (License: Personal Use)

This image shows a typical TO-220 transistor package, featuring a black epoxy body, three metallic leads (collector, base, emitter), and a silver metal tab for mounting to a heatsink. The tab often connects electrically to the collector (in NPN types) and provides mechanical stability and thermal management. Widely employed in power supplies, motor drivers, and audio amplifiers.

Used in electronics documentation, datasheets, educational content, and e-commerce product pages for discrete semiconductors; matches user intent for identifying, selecting, or learning about power transistors.
