TVS-Diodes, or Transient Voltage Suppressors, are an important component in many electronic devices and systems. The SESD0402Q2UG-0030-088 is an example of a TVS-Diode that offers excellent protection against transient voltage events like ESD, lightning surges, and inductive spikes. In this article, we will take a look at the SESD0402Q2UG-0030-088’s application field and its working principle to understand its use better.

Application Field for the SESD0402Q2UG-0030-088 TVS-Diode

The SESD0402Q2UG-0030-088 is designed to protect highly sensitive digital circuits from high frequency transient voltage events. It is ideal for use in automotive and industrial applications, and can be found in a wide variety of consumer electronics like computers, laptops, video game systems, and cell phones. The device also works well in applications that require surge and over-voltage protection such as medical devices, power supplies, and energy-efficiency systems. In addition, it can provide protection against ESD, lightning surges, and inductive spikes.

The SESD0402Q2UG-0030-088 is a low-capacitance device that can withstand high voltages for extended periods of time. Because of its low capacitance, it will not cause high frequency interference or create ground loops. This makes it an ideal choice for protection against high frequency signals and transient voltage events. In addition, the device is RoHS and REACH compliant, making it a safe and reliable choice for many applications.

Working Principle of the SESD0402Q2UG-0030-088

TVS-Diodes are used to protect sensitive circuits from high voltage events. The SESD0402Q2UG-0030-088 is designed with a robust design that incorporates a special bi-directional thyristor. This thyristor will detect the incoming voltage and activate an internal reverse current path that will draw the incoming voltage away from the sensitive circuits. This protects the circuits from damage due to transient over-voltage and surge events.

The device also includes an internal zener diode, which will draw the excess voltage away from the protected circuits and direct it to ground. This helps to limit the amount of damage that can be caused by transient events. The device is also designed with an internal ESD clamp, which helps to protect against electrostatic discharge (ESD).

Conclusion

The SESD0402Q2UG-0030-088 is a robust and reliable TVS-Diode that offers excellent protection against ESD, lightning surges, and inductive spikes in automotive and industrial applications. It is a low-capacitance device that does not create any high frequency interference or ground loops. In summary, the device is RoHS and REACH compliant, making it a safe and reliable choice for many sensitive applications.
