TVSs, or Transient Voltage Suppressors, are amazing components that have revolutionized the protection of circuits from transient voltages. This article focuses on one specific type of TVS, an V14H140P. We will detail its primary application field and its working principle.

V14H140P Application Field

The V14H140P is a 14-lead, high-performance, surface mount TVS which is often utilized for various protection applications. It is designed to offer circuit protection of waveform shifting and overvoltage transients. This component\'s primary application field is to provide over temperature protection in offline power supplies. The layout and design of the V14H140P make it suitable for broad range of power management applications such as desktops, servers and monitors.

The V14H140P is also accepted for several military-level applications that involve EMI/RFI, ESD, and transient overvoltage protection. Not only is it suitable for high-density board layouts, it\'s also well-suited for audio-video equipment, telecommunications, automotive and avionics systems.

V14H140P Working Principle

The working principle of the V14H140P is simple and efficient. The component employs the Surge-At-A-Time-Mode (SATM) principle of operation to provide over-temperature protection in offline power supplies. This component helps the electronics protect against transients caused by intermittent short circuits and production related noise.

The device clamping response is controlled by the back-to-back zener diodes in combination with an N-channel MOSFET, all which are controlled by the peak voltage of the illegal voltage clamps. The back-to-back zener diodes work as reference voltage sources, while the MOSFET provides the clamping action. The V14H140P typically operates in the single-pulse mode in which the protection is only activated when the voltage spike is greater than the rated clamp voltage.

Conclusion

The V14H140P is an important component for providing over temperature protection in offline power supplies. Its primary application field is to provide protection in a variety of industries ranging from automotive and avionics, to audio-video and information technology. The component employs an N-channel MOSFET and paired back-to-back zener diodes in order to provide efficient over-temperature protection.
