TVS - Diodes: SMBJ8.5CD-M3/I Application Field and Working Principle

The TVS - Diodes family of protection components includes multiple different configurations that provide reliable, cost-effective circuit protection from overvoltage transients. The SMBJ8.5CD-M3/I is a surface-mount diode analyzer designed for general-purpose applications. It provides 8.5 volt breakdown performance and a 1500 W peak-pulse power dissipation in an ultra-small package. This article will discuss the application field and working principle of the SMBJ8.5CD-M3/I TVS – Diode.

One application that utilizes the SMBJ8.5CD-M3/I is circuit protection for computer and peripheral devices. In these circuits, it is important to protect all device internal wiring and components from damage caused by the fast rise-times of externally sourced voltage change. The SMBJ8.5CD-M3/I provides short-duration protection against voltage spikes up to 8.5V, providing an across-the-board measure of safeguard. The product specification also states that the device provides 1500 W peak-pulse power dissipation, handling energy spikes that could occur during these events.

The device is designed to operate when subjected to voltage transients. It works in the following way. When the operating voltage reaches the breakdown voltage of 8.5V, the TVS diode turns on and begins to conduct electricity. This reduces the voltage across the device, protecting the circuit from further overvoltage. To turn it off, the device requires a significant voltage reduction across the diode, lasting a few microseconds. The device then returns to a low-capacity, non-conductive state, allowing the circuit to return to a safe level. This series of events occurs over a few microseconds and provides a level of circuit protection that may not be achievable with traditional components.

The most important component of the SMBJ8.5CD-M3/I is its ability to provide fast, reliable protection for circuits against dangerously high voltages. This device can be utilized in many different applications where it is important to protect a circuit from high-voltage transients. Its combination of small size and ultra-low capacitance make it an ideal solution for High-Speed transmission lines, as well as a variety of other applications. Additionally, its break-down voltage of 8.5V allows you to tailor the device to the specific needs of each application, ensuring maximum circuit protection.

The SMBJ8.5CD-M3/I is a simple, cost-effective solution for circuit protection throughout many different applications. Its wide range of features, such as a low capacitance design and fast response time, make it an ideal choice for protection from dangerous voltage transients. Its ability to provide reliable protection in Ultra-Small packages make it an attractive solution for a wide variety of applications, from general purpose to High-Speed transmission lines. In addition, the device\'s 1500 W peak-pulse power dissipation provides the user with the assurance that the device will protect their circuits from dangerous overvoltage.
