Introduction

Transient Voltage Suppressors (TVS) Diodes are designed and manufactured to rapidly limit voltage transients to a level that will not damage downstream components. The UPT17R/TR13 device is an innovative, high-performance, two-line transient voltage suppressor (TVS) diode specifically designed for applications involving high voltages and current. In this article, we will discuss the application field of the UPT17R/TR13 and its working principle.

Application Field

The UPT17R/TR13 is a two-line TVS diode, designed to protect against high transient voltages and currents. It is an ideal solution for automotive and transportation applications, where electronic devices have to be operated reliably in harsh environmental conditions. Typical applications include engine control units, multiplex networks, electrical power steering, active suspension systems, airbag restraints, as well as other automotive and transportation systems. The UPT17R/TR13 is also suitable for power line overvoltage protection. It is able to protect against high surge currents on ac/dc power lines, and can be used in high-power telecom transmission and distribution networks. Other applications include protection for power supplies and equipment in industrial automation, power electronics, and lighting equipment.

Working Principle

The UPT17R/TR13 two-line TVS diode uses a unique technology that allows current to be rapidly controlled during a transient or surge event. It works by clamping the voltage on both the positive and negative sides of the power supply. The device is triggered when the voltage on the power supply exceeds its maximum clamping voltage, limiting the peak voltage to a predetermined level. It is designed to reduce switching transients, and is able to respond quickly to voltage spikes. The UPT17R/TR13 offers improved performance compared to conventional TVS diodes, due to its unique reverse-side triggering feature. The device has an operating temperature range of -40°C to +125°C, and a maximum clamping voltage of 41 volts. It is also RoHS compliant, meaning that it does not contain hazardous substances such as lead or mercury.

Conclusion

The UPT17R/TR13 is a two-line TVS diode, designed for applications involving high voltages and current. It is suitable for applications in the automotive and transportation industry, as well as industrial automation and lighting equipment. In operation, the device uses a unique technology that allows current to be rapidly controlled during a transient or surge event. It offers improved performance compared to conventional TVS diodes, and has a maximum clamping voltage of 41 volts.
