TVS diodes, also known as Transient Voltage Suppressors (TPSs), are semiconductor devices often used to protect sensitive electronic components from excessive voltage. The SM8LC15E3/TR13 is a classic example of a TVS diode, and it is commonly used in a wide range of applications. In this article, we will look at the working principle behind this particular TVS diode and its typical application fields.

Working Principle

At its core, the SM8LC15E3/TR13 is made up of two components: a Silicon avalanche diode and a metal-oxide varistor (MOV). The Silicon avalanche diode, also known as a Zener diode, is a semiconductor device that uses a reverse biased voltage to induce an avalanche breakdown effect. This breakdown effect causes the diode to suddenly conduct current, creating a voltage drop in the process.

The metal-oxide varistor (MOV), on the other hand, is a special type of varistor that is made up of several layers of oxide between two metal plates. It functions as a voltage dependent resistor with adjustable resistance, creating a non-linear resistance-voltage relationship. When a voltage surge occurs, the resistance of the MOV increases dramatically, limiting the amount of current that can flow and providing additional protection to the system.

By combining these two components, the SM8LC15E3/TR13 is able to provide an efficient and reliable solution for voltage and current sensing in quite a wide range of applications. It can quickly and effectively limit the amount of voltage and current going through the system, while also reducing electromagnetic interference and other undesirable side-effects.

Typical Applications

The SM8LC15E3/TR13 is often used in consumer and industrial electronics, such as computers, tablets, and scientific equipment. It is also commonly used in automotive applications, like airbag deployment and power steering control systems. It is even used in medical equipment, such as cardiac and neuromuscular stimulator systems.

In general, this TVS diode can be used in any application where a device needs to be protected from sudden and unexpected voltage surges. By quickly limiting the amount of current that can flow, the SM8LC15E3/TR13 can help prevent damage to the device, as well as reduce the amount of electromagnetic interference that might be generated.

Conclusion

The SM8LC15E3/TR13 is a classic example of a TVS diode, and it is commonly used in a wide variety of applications, including consumer and industrial electronics, automotive applications, and medical equipment. Its efficient design, which is based on a combination of a Si avalanche diode and a metal-oxide varistor, allows it to quickly detect and limit the amount of voltage and current going through the system, while also reducing electromagnetic interference and other undesirable side-effects. Thanks to its versatility and reliability, the SM8LC15E3/TR13 is an ideal solution for voltage and current sensing in quite a wide range of applications.
