TVS - Diodes – PESD24VS2UQ,115 Application Field and Working Principle

TVS (Transient Voltage Suppression) diodes are devices developed by semiconductor manufacturers for the purpose of suppressing voltage transients. They are intended to protect sensitive equipment or circuits from the damaging effects of electrical disturbances such as electrostatic discharge, inductive load switching, lightning strikes, and electrical fast transients. The PESD24VS2UQ,115 is a small, low-power, low-leakage, non-polarized TVS diode with an operating voltage of 115V and a dynamic resistance of 5-5000Ω. It is a economical solution for transient voltage protection applications, and can be used with both AC and DC. Additionally, it features a wide operating temperature range from −65°C to +175°C and can withstand up to 500W peak pulse power. The PESD24VS2UQ,115 consists of a junction, anode and cathode. The junction is formed by a “Zener”-type junction, which is a piece of material doped with impurities of opposite types on either side. This creates an electric field in the junction which can be controlled by adjusting the doping level. When a voltage is applied to the anode and the cathode, the electric field in the junction increases until it reaches a breakdown voltage, causing current to flow through the device. This current limits the voltage rise across the junction. When a transient voltage arrives, the transient voltage causes a current to flow in the device, resulting in a voltage drop across the device. The device then dissipates the energy of the transient as heat. As a result, the voltage across the junction is limited and the transient is suppressed. As the transient voltage dissipates, the current flowing through the device drops to nearly zero volts. The diode is then ready to protect the next transient voltage spike. The PESD24VS2UQ,115 is a highly beneficial device for applications requiring protection against voltage transients. It is an economical solution for applications that require an operating voltage of 115V with a dynamic resistance of 5-5000Ω. Additionally, it has a wide operating temperature range of −65°C to +175°C and can withstand up to 500W peak pulse power. As a result, it is a reliable device for transient voltage suppression applications.
