TVS - Diodes: LXES11DAA2-137 application field and working principle

Transient Voltage Suppressor (TVS) diodes are used to protect electronic circuits from voltage transients induced by lightning and other electrical transients, and the LXES11DAA2-137 is an example of this protective diode. The LXES11DAA2-137 is a two-terminal "unidirectional" (single direction) diode which acts as a voltage regulator when the input voltage is higher than the breakdown voltage of the diode. It is composed of an N-type material with a thin P-type layer on its surface. This P-type material has a higher voltage breakdown rating, so when a transient voltage passes through the diode, the P-type layer will break down and allow the voltage to be clamped to a safe level. The peak power dissipated by the diode can be greatly reduced due to the new lower voltage level. This prevents any damage to the components of the electronic circuit.

The LXES11DAA2-137 is used in a variety of applications, such as automotive systems, consumer electronics, power supplies, and industrial equipment. It is also used in point-of-load (PoL) circuits for system power, as well as in applications such as renewable energy, solar, and other power conversion systems. It can also be used for transient voltage protection in power supply lines, as well as vehicle electronic control units and power controllers.

The LXES11DAA2-137 is part of a family of TVS diodes (LXES series) which offers a variety of features and benefits. It has a unique ceramic isolation that offers excellent electrical insulation and better heatsink performance. Its small size makes it easy to use in limited space, and its low power dissipation combined with high surge capability makes it suitable for a range of applications. It also provides regeneration capability, allowing the device to be self-protecting, which is particularly advantageous in renewable energy and charging systems.

In terms of performance, the LXES11DAA2-137 provides a wide range of protection, from transient voltage surges up to an energy level of 200W peak power (10/1000μs waveform). It has a breakdown voltage of 11V, and a peak pulse current rating up to 30A. Its clamping voltage is from 9.2-11.2V, making it suitable for a range of applications. In addition, the LXES11DAA2-137 has a low operating temperature and a fast response time, both of which are important considerations for any TVS diode.

The LXES11DAA2-137 is a widely used and versatile TVS diode with many advantages. Its low power dissipation, high surge capability, small size, and wide range of protection make it suitable for use in a variety of applications. Its ceramic isolation and fast response time also make it an attractive choice for many circuit protection systems. Ultimately, the LXES11DAA2-137 is an excellent option for protecting against transient voltage surges in a variety of devices.
