TVS - Diodes are a type of component that helps to protect pricey components and electrical systems from becoming victim of stray voltage results from electrostatic discharges (ESDs), electrical overstress, over-voltage and open ground conditions. The MPLAD30KP130AE3 is a diode manufactured by Littelfuse that belongs to this category. It offers enhanced protection from low level surge transients.

The MPLAD30KP130AE3 is a unidirectional, bi-directional, and bidirectional surface mount combo diode, and it is ideal for use for applications such as automotive, consumer electronics, computers, telecommunications, and industrial applications. A distinctive feature of this diode is its firm mechanical construction which allows for an easy automated mounting. It uses two components, consisting of a PN junction diode and a resistor connected in parallel. This diode is characterized by a very low leakage current allowing it to be used in low voltage applications.

The working principle of the MPLAD30KP130AE3 is relatively straightforward. It contributes to the expulsion of transient voltage spikes by triggering a low forward voltage drop across the diode when the applied voltage exceeds its breakdown level. This current then follows a low impedance path that delivers the depolarizing energy away from the sensitive circuit. When the applied voltage is reduced to a safe level, the diode will cut off the current, thereby preventing the voltage from coming back into the circuit. Thus, the MPLAD30KP130AE3 prevents irreversible damage to sensitive electronic components and systems.

Finally, the MPLAD30KP130AE3 has been optimized to provide the most reliable ESD protection against lightning-induced transients. One advantage of this diode is its high clamping voltage which helps reduce secondary breakdowns and subsequently decrease the total energy required to be dissipated. It also features a wide working temperature range of -40°C to 125°C, making it suitable to be used in both cryogenic and extreme hot temperature applications.

In conclusion, the MPLAD30KP130AE3 is an ideal TVS diode for protection against transient voltage spikes in various applications. It offers superior protection from low level surge transients and can be used in contexts where high clamping voltage and wide temperature range are required. The simple yet robust design also makes it one of the most reliable and cost effective solutions for overvoltage and ESD protection.
