MXLSMCG28AE3 TVS-Diodes

Transient Voltage Suppression (TVS) Diode is a general term for all devices which are able to protect circuits from high voltage transients.Such diode devices provide a low resistance between anode and cathode in normal or forward-biased operation and then switch on in reverse biased operation. when pulses from transient voltage transients exceed the avalanche voltage limit of the diode. MXLSMCG28AE3 is no different in this respect.MXLSMCG28AE3 is a 28V, 4.5W unidirectional device capable of providing transient suppression, ESD and surge protection with minimal energy storage. This device meets the requirements for IEC61000-4-4 EFT, IEC61000-4-2 ESD protection as well as REACH as defined by RoHS2. It also has a low on-state capacitance, high peak pulse current and fast, positive action.MXLSMCG28AE3 application fields include computer and network protection, automotive electrical system, telecommunications and industrial control systems. It can also be used to protect sensitive equipment from transient voltages such as lightning, power-crosses, welding and inductive switching. It should be noted that, like all surge suppressors, this diode should be used in series with lead components to prevent damage to the device caused by large transient voltages.The operating principle of MXLSMCG28AE3 is that when the voltage transient exceeds the device’s avalanche voltage, the electrons native to the diode are excited to a higher energy state. These electrons then combine with the electrons of the surrounding atoms, creating minority carriers. This quickly creates an avalanche current which shorts the device, thereby diverting the transient voltage away from the protected circuit and dissipating its energy safely.The use of MXLSMCG28AE3 does not replace other surge protection devices, such as MOV (Metal Oxide Varistors) or other protective components, but instead provides an additional layer of protection against voltage transients. This helps ensure the safety of the connected system and its occupants by greatly reducing the risk of damage caused by excess voltage.In conclusion, MXLSMCG28AE3 tvs-diodes are devices designed to protect circuits from high-voltage transients. These devices meet IEC61000-4 requirements and have a low on-state capacitance, a high peak pulse current, and fast-acting avalanche behavior. They are widely used in automotive, industrial, and telecommunications applications, providing an additional layer of protection against voltage transients.
