SelenDioden
SelenDioden, or selenium diodes, are rectifier devices that use elemental selenium as the rectifying medium. They were widely employed in early to mid-20th-century power supplies and radio and television equipment, before silicon-based rectifiers became dominant.
A selenium rectifier is typically built as a stack of discs or plates in which a layer
Characteristics and performance
SelenDioden have a comparatively high forward voltage drop and moderate to high reverse leakage, making them
Selenium rectifiers were common from the 1930s through the 1950s and into the early 1960s, used in
