 TVS - Diodes: LXES21DAA4-138 Application Field and Working Principle

TVS - Diodes, also known as Transient Voltage Suppression Diodes, are used to protect circuits from high voltage transients. Commonly used in the automotive, industrial and consumer electronics industries, these diodes are designed to protect circuits from high voltage transients, such as those that can be caused by lightning strikes or high power surges. In this article, we will look at the LXES21DAA4-138, its application field and its working principle.

LXES21DAA4-138 Overview

The LXES21DAA4-138 is a high power TVS - Diode designed to protect circuits from high voltage transients. This device has a high working peak pulse power of 5500 watts. It has a peak pulse surge current of 83A, and a clamping voltage of 137V. It has an operating temperature range of -55°C to 125°C, and has an insulation resistance value of 1000MΩ minimum. It is designed to protect against surges from lightning strikes, as well as other high voltage transients.

LXES21DAA4-138 Application Field

The LXES21DAA4-138 can be used in a wide range of applications. It is often used in the automotive and industrial sectors, as well as the consumer electronics industry. It is often used in automobiles for circuit protection, as it is designed to control transient voltage spikes up to 5500 watts. It can also be used in industrial machines, such as those found in the manufacturing or engineering industries, to protect circuits from power surges. In the consumer electronics industry, the device is often used in AC adaptors, power supply devices, computer peripherals, and other digital products.

LXES21DAA4-138 Working Principle

The working principle of the LXES21DAA4-138 is that when a high voltage transient occurs, it will “clamp” the voltage, effectively lowering the voltage to a level safe for the circuit. The device is designed to dissipate energy, so when it is triggered, it will absorb and dissipate the energy that is causing the surge. This will protect the circuit, and prevent it from being damaged. It also has a low on-state voltage drop, so there is minimal power loss.

Conclusion

The LXES21DAA4-138 is an effective high-power TVS - Diode designed to protect circuits from high voltage transients. It is commonly used in the automotive, industrial, and consumer electronics industries. It has a high working peak pulse power of 5500 watts, and a peak pulse surge current of 83A. It has an operating temperature range of -55°C to 125°C, and has an insulation resistance value of 1000MΩ minimum. Finally, its working principle is that it will “clamp” the voltage, dissipating the energy, and protecting the circuit from damage.
