TVS - Diodes Overview

TVS - Diodes are electronic components that act as a voltage-regulating device, protecting electronic equipment from high-voltage transients and spikes. Transient voltage suppressors, commonly known as TVS diodes, are widely used in industrial, automotive and medical applications due to their high surge protection levels and durability.TVS - Diodes are made up of a junction device that can provide a variety of protection levels. These include junction breakdown voltage, reverse polarity protection, reverse-bias blocking capability, transient protection, and ESD protection. A common use of TVS diodes is to provide a clamping voltage for overvoltage protection. These diodes can be used in both unipolar and bipolar protection applications.The SMLJ48CA-QH is a bipolar TVS diode, designed to protect against voltage transients and surges. It can be used in an array of applications, such as AC power line protection, surge suppression, AC motor relay switching, AC power line transient protection and EMI/RFI interference suppression. It is an active, unidirectional device which acts like a reverse-biased diode. When a voltage surge occurs, the SMLJ48CA-QH provides a fast acting clamping action and discharges the transient energy, minimizing the effect of the surge on the protected equipment.
