Transient Voltage Suppression (TVS) diodes are a type of semiconductor that can be used for overvoltage protection. PTVS3-058C-SH is a type of TVS diode that has a wide range of applications. This article will explore the characteristics of the PTVS3-058C-SH diode and explain its working principle.

Product Overview

The PTVS3-058C-SH is a molded-case, low capacitance, unidirectional TVS diode designed to protect sensitive circuitry from overvoltage transients. Its design uses Enhanced Thermal Performance (ETP™) packaging, which provides superior thermal performance and reliability in short-circuit protection. The device is compliant with IEC 60747-5-2 and IEC 60747-5-5.

The PTVS3-058C-SH diode has a bidirectional working voltage of 5.8V, with a peak pulse power rating of 1250 W. The diode is rated for an operating temperature range of -50°C to +125°C. It has a minimum breakdown voltage of 6.5V, and a maximum clamping voltage of 11V. The operating current of this diode is 4A.

This diode has a low capacitance of 0.08pF across ports, which makes it ideal for high-speed data transmit applications. The leakage current is also extremely low, making it suitable for low power applications. The device is also RoHS compliant and meets UL and cUL standards.

Working Principle

The working principle of the PTVS3-058C-SH diode is based on the working principle of most other semiconductor TVS diodes, which is to absorb a surge of current and convert it into a voltage. The device is designed to offer a very low resistance to the current flow when the voltage is below a threshold level, which is known as the clamping voltage. When the voltage rises above this level, the diode will begin to conduct and absorb the energy, effectively raising the clamping voltage and preventing the surge from damaging the protected circuit.

The way in which the device handles the absorbed current is also important. It has been designed with a built-in thermal protection circuit, which is activated when the internal temperature of the device reaches its maximum limit. The circuit will reduce the amount of current that the diode can absorb, preventing it from overheating and potentially damaging the circuit.

Applications

Due to its design, the PTVS3-058C-SH diode can be used in a wide range of applications. It is commonly used for overvoltage protection of sensitive circuits, such as laptops, tablets, or mobile phones. It is also a reliable protection option for automotive, avionics, and industrial components, which can be exposed to voltage surges.

It can also be used in data transfer applications, such as USB data cables or networking cables. Its low capacitance and low leakage current make it a suitable option for these types of applications. Additionally, its RoHS compliance makes it a suitable choice for electronics that must meet strict certification standards.

Conclusion

In conclusion, the PTVS3-058C-SH diode is a reliable and cost effective option for overvoltage protection. It can be used in a wide range of applications, from high speed data transfer to automotive and industrial components. Additionally, its low capacitance and leakage current, as well as its RoHS compliance, make it an even more attractive choice for many applications.
