Part Naming Conventions

Clicking on product's category allows you to see Diodes Part Naming Conventions.

  • Diode (JEITA Registration Products)

    Example of Diode


    1. The value that subtracted 1 from the total number of terminals
    2. S stands for Semiconductor
    3. The kind of diode
      • S: Diode of general-purpose use, detection use, frequency conversion use, and switching use
      • V: Variable capacitance diode
    4. Serial number
      JEITA registration numbers

  • SiC Schottky Barrier Diodes

    Example of SiC Schottky Barrier Diodes

    　

    1. Toshiba SiC Schottky Barrier Diodes
    2. Current rating IF(DC)
      Ex.) 10 : IF(DC) = 10 A
    3. Package
      A : TO-220F-2L
      E : TO-220-2L
      J : TO-3P(N)
      P : DPAK
