The TVS Transient Voltage Suppressor
Transient Voltage Suppression (TVS) diodes are solid state pn junction devices specifically designed to
protect semiconductors from the damaging effects of transient voltages. The electrical characteristics of
the transient protection circuit are determined by factors such as junction area, doping concentration, and
substrate resistivity. The surge power and surge current capability of the TVS diode are proportional to
the junction area. TVS diodes are constructed with large cross sectional area junctions for absorbing high
transient current. While the VI characteristic curve of the TVS diode is similar to that of a zener diode, TVS
diodes are specifically designed, characterized, and tested for transient voltage suppression. By contrast,
zener diodes are designed and specified for voltage regulation.
