Introduction

DA112S1 is a transient voltage suppression (TVS) diode device which provides an easy and efficient way of protecting electronic devices from transient overvoltage and overcurrent. This device combines the high performance of a Transient Voltage Suppressor (TVS) diode and the inherent robustness of a Field Effect diode, making it ideal for the protection of I/O interfaces, signal lines and other sensitive components.

Application field

DA112S1 has a wide range of applications. It is commonly used for the protection of signal lines, I/O interfaces, and other sensitive components. It can be used in a variety of automotive, industrial, and consumer applications such as automotive ECUs diagnotic ports, USB and HDMI ports, automotive infotainment systems, and consumer medical devices.

Working principle

When the voltage applied to the DA112S1 exceeds its breakdown voltage, it will conduct current and limit the voltage on the signal line. This is done by releasing stored energy from its proprietary Triswitch protection device. Da112S1 can also be used to protect against high-energy transient overcurrents which can cause a catastrophic failure of the protected system. The diode utilizes a high military-grade “X-treme low leakage current” up to 40 kV, providing excellent protection to the system where it is employed.

Summary

The DA112S1 device is a highly reliable, fast-acting TVS diode. It is ideally suited for the protection of sensitive components, signal lines, and I/O interfaces. With its low leakage current and robust protection, it provides a cost-effective solution for a wide range of automotive, industrial, and consumer applications.
