Selenium Suppressors

Selenium suppressors are a popular choice for engineers, they are designed to protect semiconductors from damage caused by transient surges. Selenium suppressor ratings are determined by the cell size and number of cells in a series similar to the power rectifier, they are also rated by their voltage clamping factor and by the amount of reverse energy in joules that they can absorb.

GD Rectifiers' range of transient suppressors are used in a wide selection of applications that require protection of components in the circuit, such as motor generators and inductive components.
