MSMCJ28CA Circuit Protection

TVS-Diodes are the go-to devices for protecting electronic devices from surge and transient voltages. The MSMCJ28CA is a Surface Mount type of Transient Voltage Suppressor (TVS) Diode, designed to protect electronic devices from voltage surges and transient voltages. This device is capable of safely dissipating energy up to 5 watts at both peak and continuous power, while being capable of withstanding high levels of transient voltage up to 28 volts. For many applications, the MSMCJ28CA is the ideal choice for low voltage protection.

The MSMCJ28CA is a unidirectional dual-channel diode device, meaning that it is designed to protect circuits in only one direction. It consists of two separate diodes attached parallel to each other, separated by a PN junction, and each diode is electrically equivalent. This PN junction allows for the device to conduct current in one direction and block current in the other.

The MSMCJ28CA\'s primary application field is in the protection of power supply circuits from electrical surges or transient voltage events. This type of device is typically used in power supplies, UPS systems, or other types of switching applications. These devices can be used to protect a circuit from overvoltage or overcurrent events, which if not properly managed can cause significant damage to a circuit. The protection offered by the MSMCJ28CA can help to mitigate damages caused by these events, as it can safely dissipate the energy generated by these events and reduce current and voltage levels to a safe level for the circuit.

The working principle of the MSMCJ28CA is based on avalanche breakdown. When a surge voltage greater than the rated voltage is applied to the device, electron-hole pairs are generated which causes a high current flow. This current flow is then dissipated and absorbed into the substrate material, which results in a decrease in the voltage across the device. The device will then continue to absorb higher levels of transients until it reaches its dissipation limit, where it will then reset and return to its original state.

The MSMCJ28CA also has additional characteristics that make it an ideal choice for many applications. The device is rated to withstand high levels of transient voltages up to 28 volts and is capable of dissipating energy up to 5 watts at both peak and continuous power. The device is also offered in both standard and custom voltage packages, allowing for it to be tailored to specific applications. Additionally, the device has a low thermal resistance and low leakage current, making it a great choice for applications where constant power dissipation is needed.

The MSMCJ28CA is a great choice for many applications, and can be used to protect circuits from transient voltages and surges. It offers advantages such as high dissipation, low thermal resistance, and high transient voltage capability, making it an ideal choice for many applications. With its wide range of features, the MSMCJ28CA is sure to be the ideal device for protecting power supplies and other circuits from high voltage or current events.
