Lightning and surge protection has become increasingly crucial for electronic systems, especially for advanced and connected devices. To prevent overvoltage damages, transient voltage suppression (TVS) diodes play an important role. This article will introduce the application field and working principle of the highly reliable exceptional SMB10J6.5A-E3/52 TVS diode.

As the evolving sophistication of electronic equipment and the escalating number of destroy incidents due to lightning surges, the application of TVS diodes has become necessary for modern electronic systems. TVS diodes are semiconductor components that can provide a variety of voltage limit protection devices for both the power and the signal line. This protection is not only limited to the transient voltage induced by lightning but also to internal transients.

The SMB10J6.5A-E3/52 is a surface mount silicon diode designed specifically for Telecommunications, Automotive and Industrial applications. It has a breakdown voltage of 6.5 V, transil time and peak pulse current capability of 8/20 μs at 10A respectively. With a response time of less than 1 ns, the device can provide high voltage surge protection. Its bidirectional design can protect against both the transient peak reverse voltage and voltage rise, helping to ensure that the device will not be damaged during excessive instantaneous currents.

The SMB10J6.5A-E3/52 diode works on the principle of avalanche breakdown. When a small reverse voltage is applied to the diode, electrons accumulate at thin p-n junction. This accumulation accelerates the current that is then able to inundate the junction with current, and break the atoms and molecules apart. This breakthrough generates additional electrons and holes in the junction region, creating an avalanche effect. This effect enables the device to handle higher voltage. This property makes the diode particularly suitable for protection against transient overvoltage and overcurrent.

The SMB10J6.5A-E3/52 diode is a perfect fit for applications that require robust protection against over-voltage. It is used in various automotive, industrial, and telecommunications systems, such as mobile communication, LAN, CATV, lightning protection, and automotive electronic control systems. It has a high reliability, rated with endurance of up to 10,000 hours, and a wide operational temperature range of -55℃ to +150℃.

In conclusion, TVS diodes are essential in protecting electronic systems from transient overvoltages and overcurrents, and the highly reliable SMB10J6.5A-E3/52 is the perfect choice. Its low breakdown voltage, fast response time, and wide operating temperature range make it ideal for various applications.
