TVS (Transient Voltage Suppressors) diodes are used to protect underground cables from overvoltage transients generated by lightning, electrostatic discharge, switching transients and other events. In order to achieve this high voltage protection, diode manufacturers have developed a range of specialized diodes, such as the popular 1.5KE36A.

1.5KE36A Application Field

The 1.5KE36A diode is widely used in all kinds of fast-transitioning electronic circuits, circuit boards, power supplies and telecommunications systems. It is designed to protect telecommunication systems, undersea cables and electronic circuits from the hazard of overvoltage transients generated by lightning, electrostatic discharge and switching transients.

The 1.5KE36A diode has a sharp response and is capable of suppressing voltage transients from up to 5KA (Kilo Amps). This makes it particularly suitable for applications that involve high-information protection and require fast switching. Furthermore, its 36V breakdown voltage allows it to withstand higher voltage transients. As such, it can be used in power supplies and high-current environments.

In telecommunications systems, the 1.5KE36A diode is used to protect against power and radio-frequency surges. It can be used to provide protection from both in- and out-of-band surges. This makes it an excellent choice for critical telecom systems, where a high level of protection is essential.

1.5KE36A Working Principle

The 1.5KE36A diode is an non-linear voltage device which operates based on the avalanche breakdown effect. The avalanche effect occurs when large electric fields are applied to the junction of a diode. These fields cause a point of high electric field across the junction. This then leads to an increase in current which can cause the diode to break down.

When the 1.5KE36A diode is exposed to an overvoltage transient, the avalanche breakdown phenomenon will occur and it will begin to conduct current. A large amount of current can be conducted without any potential damage to the diode due to its sharp reverse recovery times. The 1.5KE36A also provides a large thermal limit which allows it to conduct very large transients without any failure.

The 1.5KE36A also utilizes an internal metal-oxide-silicon (MOS) gate system to increase its response time. The MOS gate system not only reduces the switching time of the diode but also helps to limit the voltage when the diode is exposed to a high-transient event.

Conclusion

The 1.5KE36A diode provides excellent protection from overvoltage transients which can damage and disrupt electronics equipment. Its sharp response time, high thermal limit and MOS gate system make it a great choice for electrical circuits, power supplies and telecom systems.
