Introduction

SMB8J28CHE3/5B is a transient voltage suppressor diode, designed to protect sensitive electronic components from high-voltage spikes. Also known as a “TVS” diode, it is a special kind of semiconductor designed to quickly clamp and limit overvoltage transients to safe levels before they can damage sensitive electronic equipment or components.

Application Field

SMB8J28CHE3/5B is most useful for providing protection for sensitive components in equipment that may be exposed to high transients caused by electrostatic discharge (ESD), fluorescent lighting, and other non-linear loads. It is particularly well suited for providing protection against the most powerful transients that may cause the most damage, such as lightning and power outages. It can be used for consumer electronics, medical devices, communications equipment, aircraft, and other sensitive electronic systems.

Working Principle

When transients occur, SMB8J28CHE3/5B acts as a fast-acting switch, connecting a low-impedance path between the two device terminals to shunt the transient’s energy away from the protected components. When the voltage drops, the diode reverts to a high-impedance state, allowing normal operations to resume. Its efficiency is due to its high-speed switching, which can be as fast as 100 nanoseconds. It also offers considerable clamp voltages and low capacitance to ensure maximum protection.

Advantages

There are many advantages to using SMB8J28CHE3/5B TVS diodes for protection against transients. The most notable benefit is that they offer a much faster and more reliable response time than traditional fuses or voltage-limiting circuits. In addition, they also provide better isolation than electrostatic discharge suppressors when used in a system. And because they are built to withstand high surge voltages, they also offer greater protection against lightning and power outages. Finally, they are relatively low cost, making them a cost-effective solution for most applications.

Conclusion

SMB8J28CHE3/5B TVS diodes are an effective and economical solution for protecting sensitive electronic components from high-voltage transients. With their high response time and reliability, they can provide the needed protection against the most powerful transients that could otherwise cause damage to electronic systems. They are a cost-effective alternative to traditional fuses and voltage-limiting circuits, and they offer better isolation than electrostatic discharge suppressors when deployed in a system.
