Transil diodes, or TVS diodes, are a form of polymeric positive temperature coefficient (PPTC) voltage regulator designed to protect circuit components from overvoltage transients. The SMA5J13A-E3/61 transistor is a particular type of transient voltage suppression (TVS) diode intended for transient voltage suppression applications such as data lines, power lines, and port protection.

Application Field

The SMA5J13A-E3/61 is typically found in communications, industrial, and consumer electronics, and many other applications where transient voltage suppression is necessary. This type is designed to provide a break down voltage of 5.0 V, which as a maximum repetitive peak pulse reverse current of 1.3 A, making it ideal for protection of delicate devices against voltage and current transient surges.

The SMA5J13A-E3/61 is perfect for limiting the surge voltage in a 5.0 V system, and can be used in applications such as smart grid networks, 4K devices, cellular base stations, laptops, tablets, automotive data lines, and many other sensitive areas.

Working Principle

A SMA5J13A-E3/61 diode works on the principle of a voltage breakdown where electron charge accumulates and passes through the diode. When a voltage or a current surge above a certain threshold occurs, the electrons leaves the N-region and creates a surge of current. This current in turn flows into the P-region and stabilizes the voltage, limiting the surge and protecting the system from damage.

The SMA5J13A-E3/61 diode features a Ultra low capacitance and low leakage current which enables it to provide superior protection against overvoltage transients and current surges.

In addition to voltage regulation, the SMA5J13A-E3/61 also helps in reducing electromagnetic interference (EMI) and radio frequency interference (RFI) as it helps in suppressing voltage fluctuations effectively. This ensures that the system is clean and creates minimal disruptions during data flow or transmission.

Conclusion

The SMA5J13A-E3/61 is an excellent voltage suppressing solution for applications that require transient protection, such as consumer electronics, communications networks, and port protection. It features low capacitance and leakage current, allowing for precise manipulation of voltage and current, and helps prevent against disturbance and damage caused by voltage surges or EMI interference.
