    Molybdenum Discs and Squares

    Molybdenum discs and squares are widely used as contact materials in silicon controlled rectifier diodes, transistors and thyristors. Molybdenum has similar coefficients of thermal expansion (CTE) to silicon combined with moderate thermal conductivity, and are therefore suitable for large area power devices where considerable heat is generated.

    Further applications include the use of molybdenum as heat sink bases in IC’s, LSI’s and hybrid circuits.

    Applications

    • Silicon Controlled Rectifiers Diodes
    • Transistors
    • Thyristors (GTO ‘s)
