TVS - Diodes

A Transient-Voltage Suppressor (TVS) Diode is a diode, which helps protect sensitive electronic components from high-energy, large voltage surges. It is an essential part of circuits designed to provide protection against electrostatic discharge (ESD) and voltage transient events. Also known as surge suppressor diodes, they subdivide into different categories, such as - clamping diodes, line surge suppressors, protection diodes, and avalanche diodes. In this article, we’ll discuss the features, applications, and working principle of the SAC12-E3/73 TVS Diode.

Features

The SAC12-E3/73 is an unidirectional transient voltage suppressor (TVS) diode, which clamps at the maximum peak surge current at 12V and offers an excellent protection against ESD, latch-up, and voltage transients. The TDK SAC12-E3/73 diode is available in a 3mm x 3mm package, making it ideal for small-space and portable devices. It also features a low clamping voltage, fast-acting response time, high surge capability, and low leakage current.

Applications

The SAC12-E3/73 diode is typically used in applications such as - consumer electronics, automotive, industrial, and telecom equipment. It can be used as a protection device in data lines, Vcm, VDD, and ground lines. It is also suited for use in power converters, power supply integrity, signal line, and I/O protection.

Working Principle

When the SAC12-E3/73 diode is exposed to a transient surge, it quickly acts to reduce the voltage at its junction. The voltage is then dissipated in the form of current to the ground, protecting the sensitive components from damage. The diode works by clamping the peak voltage to a safe level, thus preventing the voltage from reaching the protected components.At the time of the transient surge, a large part of the energy is dissipated in the diode. This prevents a further rise in the voltage & the diode turns off until the surge current reaches 0, at which point, the diode is reset and begins to function again. The working principle of any TVS diode is based on this same phenomenon.

Conclusion

The TDK SAC12-E3/73 is an unidirectional transient voltage suppressor (TVS) diode, which provides excellent surge performance & fast response time. It has many applications, such as in data lines, Vcm, VDD, and ground lines. It works by clamping the peak voltage to a safe level and dissipating the voltage in the form of current to the ground, thus protecting the sensitive components from damage.
