MXL 1.5KE220CA is a commonly used TVS diode. TVS diode stands for Transient Voltage Suppressor, which is a unidirectional semiconductor component used to protect electrical circuits against overvoltage transients or voltage spikes. Overvoltage transients usually occur due to electric arcs, electric noise, lightning strikes, or induced voltages by power surges.

MXL 1.5KE220CA is a bidirectional diode specially designed for applications in which overvoltage protection is required.

Application Field

MXL 1.5KE220CA can be used in applications such as computers and peripherals, industrial and consumer appliances, automotive systems, telecommunication systems, medical equipment, and power tools. This TVS diode can also be used in high surge and oscillations of the equipment. The diode offers an ideal protection solution to ensure the longevity of the equipment in harsh environments.

Working Principle

When an overvoltage transient occurs, the protection diode begins to conduct, allowing the electrical current to flow like a normal diode. This current carries the transient energy away from the circuit, protecting the device from damage.

The protection diode works by acting as a shunt for the electrical current. It uses a reverse breakdown voltage, which is a combination of a breakdown voltage and a surge current rating. When the transient voltage exceeds the breakdown voltage, the diode turns on and conducts the current away from the protected component.

The protection diode is usually placed between the power source and the protected device. This ensures that the voltage reaching the protected device is within the specified safe range. The protection diode also acts as a limiting device that blocks high levels of current from reaching the protected device.

The protection diode also has short recovery time, which means that it will turn off quickly after the transient voltage dissipates. This helps ensure that the protected device does not remain in the overloaded state.

In conclusion, MXL 1.5KE220CA is a commonly used TVS diode, ideal for protecting electronic devices from overvoltage transients or voltage spikes. The protection diode works by shunting electrical current away from the protected device, ensuring that the voltage level does not exceed the specified safe range. The protection diode also has short recovery times, which helps to prevent the device from remaining in an overloading state.
