TVS (Transient Voltage Suppressors) Diodes are a type of voltage suppressing device. They can limit an over-voltage spike to an acceptable level by clamping action, protecting circuits from damage. With faster response time than most other types of circuit protection, this makes TVS diodes useful for protecting against very fast and often damaging voltage transients, such as lighting, inductive load switching and electrostatic discharge.

TVS diodes are used extensively for protection across more sensitive data lines on computer, communication , industrial, consumer electronics and automotive markets .DOWO independently develops, manufactures and sells TVS diodes , various types, full models, spot stock, lightning delivery, free samples. It is a power and technology co-existing circuit protection device supplier.
