TVS - Diodes

Model MXLSMBJSAC75 is a type of transient voltage suppressor (TVS) diode which is designed to provide efficient protection for power lines, circuit boards, electronics components and appliances against voltage transients caused by lightning, electrostatic discharges and electrical fast transients. This diode is both small in size and light in weight with excellent anti-surge capability, making it ideal for applications that require both high power protection and lightweight, portable equipment. It is typically used in fields, such as, automotive, industrial, computer, communications, consumer electronics, and information technology.

Applications

The MXLSMBJSAC75 diode can be used in numerous applications, including: Automotive current protection, industrial power lines, power supply modules, smart phone protection, computer peripherals, LCD panels, digital cameras, TVs, in-vehicle navigation systems, USB ports, communications & consumer electronics devices, and semiconductor technology. Furthermore, due to its high surge capability, it can be used to protect power supply circuits and electronic components, including MOSFETs.

Working Principle

The working principle of the MXLSMBJSAC75 TVS diode is based on the Zener diode mechanism, which provides protection against transient voltage surges by conducting current when the voltage value surpasses its breakdown voltage. This breakdown voltage is usually set around 60V or higher, depending on the application and the device specifications. When an overvoltage event occurs, the diode starts conducting current and reduces the overvoltage to a manageable level. During the conducting period, the diode is able to absorb the current and dissipate the energy, thus preventing it from damaging the protected circuit or components.

Conclusion

The MXLSMBJSAC75 diode is very useful for protecting against transient voltage surges in automotive, industrial, computer, communications, consumer electronics, and information technology fields. It is made of light material, and is small and efficient enough to be used in portable equipment, while still having high surge capability. Its working principle is based on the Zener diode mechanism, and its breakdown voltage is usually set around 60V. The MXLSMBJSAC75 is able to absorb current during overvoltage events, dissipating the energy and preventing it from affecting the protected circuit or components.
