TGL41-82A-E3/97

TVS diodes are designed to protect sensitive electrical components from transient voltage surges, such as those caused by lightning strikes or power grid fluctuations. The TGL41-82A-E3/97 is a popular TVS diode for surge protection. This article will discuss the application field and working principle of the TGL41-82A-E3/97.

Application Field

The TGL41-82A-E3/97 is frequently used to protect communications and signal circuits, as well as DC power supplies. Typical applications include power grids, telecom, and data communications networks, cloud services, medical equipment, data and communication equipment, and industrial control systems. The device can also be used as part of a larger system for industrial and automotive applications.

The TGL41-82A-E3/97 is highly durable and able to withstand multiple surges over a long period of time. This makes the TGL41-82A-E3/97 suitable for applications that are subject to high lightning activity, since it reduces the possible damage from transient surges. The device is also designed to handle heavy current surges, and is able to switch off certain areas of the circuit if needed.

Working Principle

The TGL41-82A-E3/97 is a Transient Voltage Suppression (TVS) diode. It works by limiting the amplitude (voltage) of electrical transients during surges. When the diode is triggered, it begins to conduct, and voltage is diverted away from sensitive electrical components in the circuit. The device is designed to protect against both bidirectional and unidirectional transients.

The TGL41-82A-E3/97 uses an ultra-fast silicon carbide avalanching diode to limit the amplitude of transient surges. The device has a low clamping voltage of 4.7V, which is also referred to as the "breakover" voltage. This means that the diode will be activated when the voltage at the protected circuit exceeds 4.7V. It also has a current rating of 100A, which means that it can handle up to 100A of current surge.

In addition, the TGL41-82A-E3/97 is designed to be extremely temperature-stable. The device is manufactured to have a temperature coefficient of less than 20ppm/°C. This means that its characteristics will not change significantly when the ambient temperature changes. This stability is extremely important for applications that will be subject to wide temperature ranges.

Conclusion

The TGL41-82A-E3/97 is a popular TVS diode for surge protection. It is intended for a variety of applications, such as power grids, telecom, and data communications networks, as well as DC power supplies. The device is also highly durable and able to handle multiple surges over a long period of time. The device works by limiting the amplitude of electrical transients during surges, and is also extremely temperature-stable.
