Pre-packaged kits of surface mount and through-hole discrete semiconductors are curated for evaluation, demonstration, and experimentation purposes. These kits, housed in books, boxes, or plastic bins with bin guides, include assortments of MOSFETs, rectifier diodes, transistors, or Zener diodes. They are organized based on the required number of values and quantities for each value, providing a convenient solution for accessing a range of semiconductor components essential for various technical assessments and prototyping activities.
