TVS - Diodes

Transient voltage suppressors (TVS) are components designed to protect electrical and electronic equipment against voltage transients. TVS are available in either unidirectional or bidirectional models depending on the required protection. They are also available in a variety of form factors, including axial-leaded diodes, SMD diodes, IGBT modules, etc., allowing easy integration in various circuit designs. One popular form factor for TVS diodes is the SM05-TP.

SM05-TP Application Field

The SM05-TP is a 3-pin transient voltage suppressor that provides protection against electro-static discharge (ESD) and other transients. It is suitable for use in equipment for applications such as personal computers, servers, LCD TVs, printers, and set-top boxes. The ability to handle both ESD and other transients makes the SM05-TP ideal for applications where electrical overstress (EOS) protection is needed.

SM05-TP Working Principle

The SM05-TP features a specially designed semiconductor junction that is able to conduct the high levels of current associated with transients. The transient voltage is clamped to a maximum voltage by the TVS diode, preventing further voltage increases and protecting the equipment from EOS. In addition, the SM05-TP also features a reverse-bias current limit, which acts to reduce inrush current during power-up, thus improving circuit reliability in the long run.

Conclusion

The SM05-TP is a great choice for applications where transient protection is needed. Its three-pin design makes it easy to integrate into circuit designs and the specially designed semiconductor junction ensures quick response to transient voltages. In addition, the reverse-bias current limit improves circuit reliability by limiting inrush current. All in all, the SM05-TP is a great choice for applications looking for reliable and robust transient protection.
