TVS diodes (Transient Voltage Suppression), as the name suggests, are special silicon semiconductor devices whose function is to protect a complex system from various external electric transient voltage and other overvoltage spike sources. The MPLAD 7.5KP12AE3 is one such device.

Overview of the MPLAD 7.5KP12AE3

The MPLAD 7.5KP12AE3 is a unidirectional transient voltage suppressor (TVS) diode, designed to protect sensitive electronic circuit components from ac/dc transient voltages. It is designed using a planar, high-voltage sputtered integrated construction, and is capable of providing high levels of protection from spikes in both positive and negative power or signal lines. It is available in a small 1206 package, and can provide a transmission line protection of up to 500 watts peak power in a single device.

Application Field of the MPLAD 7.5KP12AE3

The MPLAD 7.5KP12AE3 is designed for use in industrial, datacom, automation, and consumer applications where voltage transient protection is needed. It is commonly used in devices that require high levels of protection from overvoltage and undershoot, such as in power supplies, on automotive circuits, and in industrial test and measurement devices. In addition, it can also be used in satellite and cell phone communications, military, and aerospace applications, where high levels of transient protection is required.

Working Principle the MPLAD 7.5KP12AE3

The MPLAD 7.5KP12AE3 works by clipping off transients before they reach sensitive components or circuits. It is designed to dissipate energy through its breakdown voltage while passing current. This helps reduce the voltage and the current at the point of protection.

When a voltage spike occurs, the device acts as a protective fuse and can be triggered at different levels, depending on the type and magnitude of spike. Once the voltage spike exceeds the breakdown voltage of the device, it quickly diverts the surge current away from the protected components or circuits. This reduces the risk of electrical damage caused by transient voltages and allows the components or circuits to return to their normal operating state.

The MPLAD 7.5KP12AE3 is capable of withstanding transient stress up to 500 watts peak power and is able to handle up to 2000 volts of transient voltage at 1.2kA of peak surge current. This makes it effective for use in power supplies, automotive circuits, industrial test and measurement circuits, and communication systems.

Conclusion

The MPLAD 7.5KP12AE3 is an effective TVS diode designed for protection of sensitive components and circuits from external electric transient voltages and other overvoltage spike sources. It provides high levels of protection from overvoltage and undershoot, and can handle up to 500 watts peak power in a single device. The device is commonly used in automotive, industrial, communications, and consumer applications and can provide an invaluable shield against electrical damage caused by transient voltages.
