About Transient Voltage Suppressor Diodes (TVS)

Transient voltage suppressor (TVS) diodes are designed to limit over-voltages. They can dissipate high amounts of transient power in a short period of time. Transient voltage suppressor diodes are available in single-chip configurations or diode arrays. A single-chip TVS consists of one diode built into the chip. A TVS diode array is composed of multiple, discrete, usually unconnected diodes on a single silicon chip. Transient voltage suppressor diodes also differ in terms of direction. Unidirectional TVS diodes provide protection when current moves in only one direction. Bidirectional TVS diodes provide protection when current moves in both directions. Transient voltage suppressor diodes that are sold in Europe must comply with the Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive from the European Union (EU). The pin count and the number of embedded TVS diodes are factors to consider when specifying an integrated circuit (IC) package. 

Performance specifications for transient voltage suppressor diodes include peak pulse power, maximum working voltage, maximum peak impulse current, clamping voltage, peak forward surge current, breakdown voltage, terminal capacitance, and operating temperature. Peak pulse power is the maximum power that transient voltage suppressor diodes can protect. The maximum working voltage is the continuous (DC) or peak voltage that can be applied to the device over the operating temperature range. When selecting a TVS, this voltage should be larger than the voltage of the device to be protected. Clamping voltage is the peak voltage across the suppressor, or the maximum voltage that the TVS will prevent. Peak forward surge current is the maximum allowable surge value of forward current without repetition. Breakdown voltage is the reverse voltage at which a small increase in voltage results in a sharp rise of reverse current.

Products & Services Related to Transient Voltage Suppressor Diodes (TVS)

Current Limiting Diodes
Current limiting diodes (CLD) regulate current over a wide voltage range. There are several types of current limiting diodes (CLD). Examples include a current regulator diode, constant current diode, and current limit diodes.
General Purpose Diodes
General-purpose diodes are electric components that conduct electric current in only one direction, functioning similarly to a one-way valve.
High Voltage Diodes
High voltage diodes are designed for use in high-voltage applications.
Rectifier Diodes
Rectifier diodes are designed for use in rectification circuits. Rectifiers are used to convert AC to DC.
Schottky Diodes
Schottky diodes in their simplest form consist of a metal layer that contacts a semiconductor element. The metal / semiconductor junctions exhibit rectifying behavior (i.e., the current passes through the structure more readily with one polarity than the other).
Step Recovery Diodes
Step recovery diodes produce an abrupt turn-off (step) time by allowing a very fast release of stored charge when switching from forward to reverse bias, and from reverse to forward bias.
Zener Diodes
Zener diodes are PN junction devices that are designed to operate in the reverse-breakdown region.
