TVS-Diodes

TVSs (Transient Voltage Suppressors) are semiconductor components used for protecting sensitive electronic circuits and components against over voltages. They are available in a variety of styles and packaging configurations, as well as fabrication technologies such as SCRs, zeners, TVSs, and other devices. One of the most popular TVS products is the 15KP48A. This component features low clamping voltages and ultra-low capacitance, making it ideal for protecting highspeed digital circuits.

15KP48A Application Field

The 15KP48A has been designed for use on mobile and other LVDS interfaces, which carry data at high speeds and high voltages. It can also be used for overvoltage protection applications in a variety of other fields, such as automotive electrical systems, communications systems, and consumer electronics.

15KP48A Working Principle

The 15KP48A has a two-stage protection system. In the first stage, the integrated electrostatic discharge (ESD) protection, which consists of a diode pair, is used to dissipate ESD transients faster than normal ESD on LVDS lines, as well as peak rapid transients. All thresholds are adjustable, providing fine-tuning for specific protection requirements. In the second stage, the TVS component is used to absorb the remaining ESD pulses which may exceed the trip points of the integrated ESD protection. The 15KP48A has a clamping voltage of 17V and is designed to operate at a peak power dissipation of 15W. It is also available in various package sizes to accommodate different application requirements.

Conclusion

The 15KP48A is a versatile transient voltage suppressor, which is suitable for both high-speed LVDS and other overvoltage protection applications. Its two-stage protection system ensures reliable performance, and its adjustable thresholds make it easy to customize the protection levels for different applications. Its low capacitance and low clamping voltage make it an attractive solution for protecting high-speed digital circuits.
