The MPLAD15KP18AE3 TVS-Diodes are designed for installed protection against surge pulses on differential and common-mode interfaces. These PulseGuard® products offer an alternative to other types of safety features, such as circuit breakers and fuses, as they can be easily integrated into electronic circuits in the production line. This makes the MPLAD15KP18AE3 ideal for use in a wide range of applications, from automotive to medical and industrial.

The MPLAD15KP18AE3 is a two-terminal device primarily designed to protect against surge pulses of very short duration. The device consists of a low impedance laterally diffused metal oxide semiconductor (LDMOS) diode and an internal protection element. The LDMOS diode provides the reverse conduction protection to ensure the integrity of the interface, and the protection element helps to absorb the energy of the surge pulses with minimal additional degradation.

The MPLAD15KP18AE3 has a maximum operating voltage of 18 volts and a maximum continuous forward current of 15 amperes. It has a total power dissipation of 0.15 watts, and a very low clamping voltage of 6 volts. The device is highly reliable and has an operating temperature range of -30°C to +85 °C. It also has a very wide surge protection range, up to 400 watts.

In terms of its working principle, the MPLAD15KP18AE3 acts as a voltage clamp. When a surge pulse is detected, the LDMOS diode is driven into conduction and the protection element acts as a shunt, causing current to flow around the circuit and absorb the energy of the surge. This helps to maintain the high reliability of the interface and protect it from surge damage.

As such, the MPLAD15KP18AE3 is an ideal choice for applications that require protection from differential and common-mode surge pulses in a variety of industries. Its high reliability and low clamping voltage make it ideal for automotive, medical, and industrial applications. It is also suitable for applications that require additional support for systems with weak power supplies, as it can absorb more surge energy than other types of protection.

Overall, the MPLAD15KP18AE3 is a highly reliable and versatile device designed to protect electronics from surge pulses. Its two-terminal design and low clamping voltage make it suitable for use in a wide variety of applications, including automotive, medical, and industrial.
