TVS (transient voltage suppressors) diodes, also known as protective Thyristors, are semiconductor components designed to quickly and reliably reduce the magnitude of transient voltage and current events that could otherwise cause severe damage to sensitive electronic components and systems. The TPSMP8.2HM3/84A is a type of TVS diode, and in this article we will discuss its application field and working principle.

The TPSMP8.2HM3/84A is a low-capacitance, unidirectional diode intended for use in a variety of applications. Its impressive transient voltage suppression capability combined with its low leakage current makes it suitable for robust operation in automotive, telecom/data, and industrial applications. It is typically used on power supply lines, data lines, and ESD lines as a means to protect against lightning and electrostatic discharge.

In terms of physical configuration, the TPSMP8.2HM3/84A is constructed in a 4-lead S0-8 package. This package features a small body, allowing it to be installed in partially populated applications. Additionally, since the device is RoHS compliant, it can be used safely in various hazardous locations.

The working principle of the TPSMP8.2HM3/84A involves the operation of its integrated Zener diode and silicon avalanche diode. The Zener diode works by allowing a certain amount of current to flow when the surge voltage exceeds its rated voltage. This normally happens in a fraction of a second thereby limiting the total energy absorbed by the TVS diode. The silicon avalanche diode then works by cutting off other voltage above the Zener diode\'s rated voltage and shunts excessive current away from sensitive components.

In short, the TPSMP8.2HM3/84A is an impressive TVS diode designed for quick and reliable voltage and current suppression. Its low capacitance and low leakage current make it ideal for automotive, telecom/data, and industrial applications, while its small size and RoHS compliance make it suitable for installation in a variety of hazardous locations. It works by combining the operation of its Zener diode and silicon avalanche diode to effectively limit the energy absorbed by the device.
