TVS (Transient Voltage Suppressor) diodes are used to protect sensitive electronic circuitry from transient voltage surges. The MSMLJ90AE3 is a bidirectional 5-12V TVS diode, which includes several series and package types depending upon component selection requirements. This article will focus on the application fields and working principle of MSMLJ90AE3, and shed light on how this component is used in various industries.

The MSMLJ90AE3 is mainly used in communication and automotive electronics for the protection of sensitive electronic components from over-/under-voltage or electrostatic discharge. The component has a working voltage exceeding its maximum avalanche energy by many orders of magnitude, which makes it highly reliable for voltage peak clamping. Its wide range of operating temperature (from -65°C to +150°C) make it suitable for harsh environment and allows to improve the reliability and working life of various electronic systems.

The MSMLJ90AE3 diode works on the principle of two electric fields which are encountered when a current passes through it. In the reverse direction, it works as a Zener diode which creates a breakdown voltage. Similarly, in the forward direction, it works as a avalanche diode which generates an avalanche voltage. When a voltage surge of more than the breakdown or avalanche voltage is applied across the diode, both fields interact to reduce the voltage. This allows the diode to absorb and dissipate the energy of the surge, thus protecting the underlying system.

The MSMLJ90AE3 diode is used in a variety of applications. It is commonly used to protect circuit elements in solar inverters, uninterruptible power supplies, and DC/DC converters. It is also suitable for protecting sensitive components in automotive, consumer electronics, and industrial equipment. In the medical computer system industry, the diode can be found in portable medical monitoring equipment, ventilators and imager systems.

In the communications industry, the MSMLJ90AE3 diode is used to provide protection from over-/under-voltage surges and electrostatic discharge in the networking infrastructure. Telecom equipment including base stations, fiber-optic systems, and test equipment can all benefit from the use of this component. Similarly, in the computing industry, the diode can be found in the circuits connecting PCs, servers, and laptops.

Finally, the MSMLJ90AE3 diode can be used in the aerospace Industry, where it can provide lightning and surge protection in commercial and military planes and satellites. Its low power dissipation, low operating current and high surge capability make it especially well-suited for this particular application.

In summary, the MSMLJ90AE3 diode is a very versatile component which offers excellent protection against voltage surges and electrostatic discharges while providing excellent reliability and longevity for electronic systems. It is commonly used in computing, automotive, medical, and aerospace industries, and its broad operating temperature range makes it an ideal choice for harsh environments.
