SM5S14AHE3/2D

TVS - Diodes, or Transient Voltage Suppressors, are protective devices used to guard against electrical spikes or surges. These electrical ”spikes” can cause damage to equipment and sensitive electronic components in a number of ways. A TVS diode is specially designed to provide protection from high frequency transient voltage spikes.

SM5S14AHE3/2D is an example of TVS Diode which offers a high power surge protection in a miniature, low-profile form factor. This device provides an ESD protection with protection capability of 14A at 8/20 micro seconds and power dissipation of 5W, with a peak square pulse power rating of 50W. The working principle of the SM5S14AHE3/2D is simple; it triggers an avalanche breakdown when an over voltage occurs, allowing the voltage to be clamped to its breakdown voltage.

The primary application field of the SM5S14AHE3/2D is over-voltage and over-current protection in consumer electronics like mobile phones, tablets, and other handheld devices. It is designed for high power applications where maximum surge protection is a requirement. Other applications can include servers, telecom, DVRs, and embedded systems, which require reliable protection for any surges coming from the input side. This diode can also be used for lightning protection, where transients need to be prevented or kept under control.

In multiple circuit applications, two or more TVS arrays will be used in conjunction. These arrays can be placed in a daisy chain, thus forming a greater protection coverage with smaller SMT footprints. This can be beneficial in a number of situations since protection arrays allow for individual protection of different parts of a circuit, while saving costs and space.

Overall the SM5S14AHE3/2D is a perfect solution for high power applications which require a reliable protection from over-voltage and over-current. The low profile and miniature footprint makes it ideal for consumer electronics as well, and with the correct implementation of protection arrays, it can be an effective tool in numerous applications.
