TVS-diodes or Transient Voltage Suppression diodes are a specialized type of protective semiconductor designed to protect electronic circuits from voltage transients and other electrical disturbances in order to maintain proper performance and data integrity. The SZESD7351HT1G is a popular TVS diode that is used in many applications. This article will discuss the application field and working principle of the SZESD7351HT1G.

The SZESD7351HT1G is a fast, dual-channel, high-voltage transient voltage suppressor designed to protect against electromagnetic interference from high-frequency noise, as well as overvoltage conditions up to 330V. It is capable of dissipating up to 800W/600W of power per channel, making it an ideal choice when a higher power level is desired. The device consists of two Schottky-style diodes in parallel for a nominal breakdown voltage of 30V and has a fast clamping response time of 5ns. It also features a low thermal resistance junction-to-ambient heatsink of 1°C.

The SZESD7351HT1G is commonly used in telecom, automotive, industrial, and consumer electronics. In telecom applications, the device is used to protect against overvoltage and transient voltage surges on copper lines, as well as air gaps. In automotive and industrial applications, the device is often used to provide surge protection in the power supply systems of electronic systems, preventing the system from damage due to excessive current. And in consumer electronic products, the device is commonly used to ensure proper protection against voltage transients in systems such as portable computers, tablet PCs, digital cameras, and portable sensors.

The SZESD7351HT1G works by detecting when a voltage transient exceeds its breakdown voltage, at which point it quickly conducts electric current away from the line to ground. The resulting current flow is known as the "clamping voltage", which is determined by the product of the unit\'s breakdown voltage and its transient current ratings. This clamped voltage is then sustained until the voltage transient falls back within a safe range.

The SZESD7351HT1G is a highly reliable and versatile TVS diode that can be used in a wide range of applications. It is an effective device for providing protection against voltage transients in a wide variety of electronic systems. It is also capable of withstanding high power levels and is easy to install and use. This makes it an ideal choice for those looking for a reliable and cost-effective solution for protecting their electronic systems.
