Surge protection devices (SPDs) are important components in modern electrical systems. SPDs play a critical role in protecting sensitive electronic components from potential damage due to spikes in power. The 1.5SMC120CA TR13 is a high-performance transient voltage suppression (TVS) diode designed to protect your system from transients caused by electrostatic discharge (ESD), lightning, and other transient events. This article will provide an overview of the 1.5SMC120CA TR13’s application field and working principle.

Application Fields

The 1.5SMC120CA TR13 is a surface mount diode with unidirectional protection and is suitable for board-level protection in a variety of applications. These include line-powered communication systems, consumer electronics, industrial equipment, and automotive applications. It has a response time of less than 10ns and is rated at 1.5A peak current and 800 watts peak power.

The 1.5SMC120CA TR13 is designed to provide protection from voltage transients in a wide range of environmental conditions. It has a working voltage of 12V and can handle voltages up to 150V when subjected to ESD. It also has a low leakage current of 10uA at 100V, which makes it suitable for low-power systems.

Working Principle

The 1.5SMC120CA TR13’s working principle is based on the avalanche breakdown of a semiconductor junction. When an overvoltage is applied to the junction, the diode is “triggered” and the voltage is diverted to ground. This diverts the excess voltage away from sensitive components and protects them from damage.

The diode also provides ESD protection by dissipating the excess charge through its internal structure. When a high voltage is applied to the diode, the potential between the anode and the cathode rises, and electrons are accelerated across the junction. When the electrons collide with the anode, they are collected and the extra energy is dissipated as heat.

The 1.5SMC120CA TR13 is a versatile TVS diode and is designed to protect your system from spikes in power. Its highly reliable design makes it suitable for a variety of applications, including consumer electronics, industrial equipment, and automotive applications. It is capable of withstanding voltages up to 150V and provides low leakage current, making it an ideal choice for low-power systems.
