A Transient voltage suppressor (TVS) diode is a type of electronic passive component that is capable of providing protection against transient voltage spikes on an electrical power line. TVS diodes are commonly used in a wide variety of applications, including automotive, industrial, and consumer electronics. The SM8LC15/TR13 is a transient voltage suppressor (TVS) diode specifically designed for automotive and industrial applications. This device offers a UL approved peak power of 1.5kW at 1ms, and a minimum breakdown voltage of 18V.

Overview

The SM8LC15/TR13 is a unidirectional Transient voltage suppressor (TVS) diode specifically designed for automotive and industrial applications. It is capable of providing protection against transient voltage spikes on an electrical power line, helping to prevent damage to electrical and electronic components. The device has a peak power of 1.5kW at 1 ms and a minimum breakdown voltage of 18V. In addition, the SM8LC15/TR13 has a forward voltage of 900mA and a reverse leakage current of 10µA, making it suitable for various applications.

Application Fields

The SM8LC15/TR13 is suitable for a wide range of applications, including automotive, industrial, and consumer electronics. It is particularly suited for applications that require a high level of transient voltage protection, such as automotive power lines, industrial power lines, and telecommunications networks. Additionally, the device can also be used in applications that require low capacitance and ESD protection, such as portable medical equipment, USB ports, and other sensitive electronic components.

Working Principle

The SM8LC15/TR13 works by using a combination of a breakdown diode and a Zener diode in series. The breakdown diode holds the voltage on the line at a steady level until it receives a brief surge in voltage. The Zener diode then keeps the voltage from exceeding the breakdown voltage, causing the current to be diverted and safely dissipated as heat. The SM8LC15/TR13 is designed with a low capacitance so that it can react quickly to protect the power line from voltage spikes.

Advantages

The SM8LC15/TR13 has several advantages, including its high peak power of 1.5kW, its UL approved rating, its low forward voltage of 900mA, and its low reverse leakage current of 10µA. It also has a fast response time and is protected against overvoltage. In addition, it is RoHS compliant, and its small package size makes it suitable for a wide range of applications.

Conclusion

The SM8LC15/TR13 is a Transient voltage suppressor (TVS) diode specifically designed for automotive and industrial applications. It is capable of providing protection against transient voltage spikes, and it has a peak power of 1.5kW at 1 ms and a minimum breakdown voltage of 18V. Additionally, the device has a low forward voltage of 900mA and a reverse leakage current of 10µA. The SM8LC15/TR13 is suitable for a wide range of applications including automotive, industrial, and consumer electronics, due to its fast response time, high peak power, and small package size.
