Application Field

The SMB10J8.0HE3/52 is widely used in automotive electronics, including both vehicles and electronic control units. It is an ideal solution for providing fast over-voltage protection against ESD, EFT and other high surge voltages. It is designed for use in a wide variety of electronic protection tasks, such as motherboard protection, cell phone protection, and protection against potential micro-cracks in electronic devices. Moreover, it is also suitable for high-speed communication systems, such as LTE/GSM/3G, gigabit Ethernet links, 10G SFP+, and high-definition television. It can meet the surge protection requirements from 0.5A to 14A.

Working Principle

The SMB10J8.0HE3/52 consists of two avalanche breakdown diodes with integrated over-voltage protection. When a surge voltage is encountered, the avalanche breakdown diodes clamp the voltage to a predetermined level, limiting the amount of current that is able to flow. This ensures that the unprotected devices are not damaged as a result of the surge voltage. The integrated over-voltage protection ensures that the devices can cope with an over-voltage situation without any permanent damage. Furthermore, the device also contains thermal capacitor protection, which ensures that the device is able to withstand the high temperatures that can occur during a surge event. This ensures that the device is able to maintain its protection capabilities even during very high temperature events.

Conclusion

The SMB10J8.0HE3/52 is a versatile TVS Diode which is ideal for a range of applications. It is capable of providing fast over-voltage protection against ESD, EFT and other high surge voltages. Furthermore, it also features integrated over-voltage protection and thermal capacitor protection, ensuring that the device is able to withstand the high temperatures that can occur during a surge event.
