TVS-Diodes are an important type of diode which are used for transient voltage suppression. This type of diode is particularly useful in applications where a high level of transient voltage performance is required. The SMP24A-M3/84A is a particular type of transient voltage suppressor diode which is designed for high frequency operations. This article will discuss the application field and working principle of the SMP24A-M3/84A.

The SMP24A-M3/84A is designed for protection of data lines, sensors, and other I/O interfaces from electrostatic discharge (ESD) and other transient voltage events. It is particularly well suited for electrostatic discharge protection up to 30kV, with a clamping voltage of less than 30V at 1.0 Amp. It is also suitable for EMI/RFI noise control in high speed communications. Additionally, the SMP24A-M3/84A is suitable for protecting automotive electronics, consumer electronics, industrial equipment, personal computers, telecommunication equipment, and other digital systems.

The working principle of the SMP24A-M3/84A is based on its modular construction. A multi-level guard ring protects against transient pulses up to 30 kV. This modular construction combines a selection of three components to optimize protection from ESD events: a low-voltage Zener diode, a blocking diode, and a varistor. The low-voltage Zener diode acts as a shunt device to route excess voltage away from the protected component, while the blocking diode acts as an electrolytic capacitor, storing some of the energy produced by the transient event. The varistor then dissipates the remaining energy, providing additional protection.

The SMP24A-M3/84A has a high peak pulse power rating of up to 60W, and a low leakage current of less than 5uA. This ensures that the diode is able to handle large transient voltage events without significant degradation of the signal integrity. Additionally, the SMP24A-M3/84A is able to operate quickly, enabling fast response times for the protection of sensitive components.

In summary, the SMP24A-M3/84A is a high performance transient voltage suppressor ideal for ESD protection up to 30kV. Its modular construction allows for high speed operation, and its high peak pulse power rating and low leakage current ensure that it is able to protect sensitive components from large transient voltage events. Additionally, its broad range of applications makes it an ideal choice for use in both industrial and consumer electronics.
