Transient voltage suppressor diodes (TVS) are a type of unidirectional components generally used for suppressing transient over voltages. The MXSMCGLCE48AE3 is a TVS diode that serves as a reliable surge protectors and also as a perfect protection device for high-power applications. This device is fabricated in a planar multilayer bridge configuration with excellent thermal design, offers high surge capability and precise triggering overvoltage protection. This diode is mainly used in portable electronic devices, consumer electronic products, home equipment, telecom systems, computer motherboards and solar panels.

The MXSMCGLCE48AE3 diode is a wide capacitance voltage surge protection product with ESD and surge protection characteristics. This TVS diode is a monolithically integrated structure and contains a Zener diode with a unipolar junction transistor. The device is fabricated with the monolithic technology, guarantees a low dynamic resistance and a high surge peak current capability. The diode can withstand high voltage transient surges up to 1kV at pulse width of 8/20μs.

The main application of the MXSMCGLCE48AE3 diode is to protect electronic systems and components against damages from ESD, EFT and surges. The device has the ability to handle a wide range of applications by providing a wide range of power current options ranging from 0.8A to 1.6A. Besides, it has low thermal resistance and wide capacitance up to 150pF in a SOD-123 package.

The working principle of this TVS diode is based on a fast reverse-connecting mechanism between the terminals of the diode and the voltage line experiencing transients. This reverse connection is active when the voltage of the line exceeds a certain threshold, established by the zener voltage. Once the voltage level reaches the zener voltage, the circuit turns into a low impedance path which allows the current to flow from the line to the diode terminals.

When transient over voltage events occur, the MXSMCGLCE48AE3 diode then turns on and clamps the voltage value in the safe level. Depending on the power capability of the diode, the device will then dissipate the excess of voltage as heat, keeping the termination safe from damages. This diode also broadens the protection from one line to multiple, giving added protection and improved performance to the entire system.

In conclusion, the MXSMCGLCE48AE3 TVS diode is an excellent protection device for protecting electronic systems. It is a low cost and reliable protection offering high capabilities at pulse widths of 8/20μs. Additionally, it has the ability to dissipate a wide range of power current, making it suitable for a variety of high power applications. As mentioned previously, the device is suitable for applications such as consumer electronics, home equipment, telecom systems, solar panels and computer motherboards.
