Today, a wide variety of protection circuits are used in modern electronic designs. TVS Diodes, or Transient Voltage Suppressors, are one of the most commonly used form of protection circuits. In this article, we will discuss the application field and working principle of the SMB8J6.5CAHE3/5B, which is a form of TVS diode.

Most of the times, ordinary diodes are used for protection purposes, such as in circuit protection and overvoltage protection. However, TVS diodes offer more protection than regular diodes do.The SMB8J6.5CAHE3/5B is a breakdown voltage of 6.5V with a peak pulse power rating of 250W. The diode, as a surge protection device, is rated for 1A of continuous forward current.

When it comes to applications, the SMB8J6.5CAHE3/5B can be used for a variety of different types of electronic circuits including communication systems, power supplies, industrial automation systems, and automotive electronics. The diode is designed for use in various locations such as the input of the power amplifier, parallel lines, power control, line protection, and bus bars. Furthermore, it can be used for both AC and DC circuits. Additionally, this diode has the capacity to suppress transient overvoltage overshoot with low clamping voltage and high peak current. This makes it highly suitable for suppressing the ESD (electrostatic discharge) of devices.

The working principle behind a TVS diode is based on the breakdown voltage of the component. When the voltage is increased beyond the diode’s breakdown voltage, the current will begin to increase exponentially. This increase in current is what allows the diode to suppress voltage transients. The SMB8J6.5CAHE3/5B, specifically, has a peak pulse power rating of 250W, making it suitable for suppressing high voltage transients.

The SMB8J6.5CAHE3/5B is a highly reliable form of protection circuit and it is only further made more reliable by the integrated temperature sensing. This temperature sensing allows the diode to sense when the temperature of the surrounding environment is increasing to a notable level. When this happens, the diode will automatically switch off to prevent the surrounding area from further absorbing the excess heat. This feature makes the SMB8J6.5CAHE3/5B even more reliable and secure.

In conclusion, the SMB8J6.5CAHE3/5B is an excellent form of TVS diode and it is highly suitable for a broad range of applications. Thanks to its integrated temperature sensing, the diode is even more reliable than a regular diode, making it one of the most commonly preferred protectant circuits today.
