SAC8.5 TVS - Diodes Applications and Working Principles

Transient Voltage Suppressors (TVS) - diodes are a family of integrated circuit (IC) devices, one of the most integral components of modern electronics. TVS - diodes provide protection against overvoltage conditions, such as those caused by electrical transients, inadequate AC line filtering, or Electrostatic Discharge (ESD). They are designed to absorb rapid voltage surges and dissipate them as heat, preserving the integrity of the system into which they are incorporated. This article will provide a description of the properties and applications of the SAC8.5 TVS - diode, and explain how it works.

The SAC8.5 TVS - diode is a popular device used in modern electrical systems. Its low on-state resistance (RDS(on)) makes it ideal for use in both high-current and low-current systems. Additionally, its tight voltage clamp protects up to 8.5 volts, limiting the voltage across the input/output terminals. Its 50 V reverse voltage rating ensures reliable protection against overvoltage conditions. As a result, it is widely used in a variety of consumer and industrial applications, such as automotive electronics, healthcare devices, power supplies, computers, and networking equipment.

The SAC8.5 TVS - diode is constructed from a pair of metal-oxide varistors (MOVs). Each MOV acts as a nonlinear resistance, dropping its resistance with increasing voltage. The MOVs are connected in parallel, providing a low on-state resistance and high breakdown voltage. When a transient voltage is applied, the TVS - diode acts as a short circuit, diverting the current away from the system and dissipating it as heat. The time-dependent dissipation is enabled by the internal capacitance of the TVS - diode, which slowly releases the absorbed energy. This dissipates the surge energy in a controlled manner, preventing it from damaging other components in the system.

The SAC8.5 TVS - diode is also equipped with an internal clamping voltage mechanism that ensures stability of its response. This ensures that it can handle large transient voltages without creating secondary transients in the circuit. Additionally, its surge current rating is tailored to meet specific application requirements, allowing it to handle large transient currents without damage to the device.

In summary, due to its tight voltage clamp, low on-state resistance, high reverse voltage rating, surge current capability, and built-in transient suppression mechanism, SAC8.5 TVS - diodes are widely used in modern electrical systems for protection against overvoltage conditions. They are an indispensable component in the construction of many consumer and industrial products, providing reliable protection for the system in which they are installed.
