MXLSMLJ20CAE3 Circuit Protection

The MXLSMLJ20CAE3 is a TVS – Diodes device, that provides a wide range of protection from high voltage transients. It is a low-leakage, high energy plated Silicon Avalanche Diode, with a unidirectional rated stand-off voltage of 20V. This diode provides low leakage current at peak voltage of up to 10V, and a low voltage transient differential of less than 1V. Due to its ability to provide protection across a wide range of applications, the MXLSMLJ20CAE3 is often used in high voltage applications such as cellular phones, notebook PCs, PDAs, and medical equipment.The application field and working principle of the MXLSMLJ20CAE3 can be broken down into five primary segments; breakdown voltage, peak pulse current, peak pulse reverse path power dissipation, leakage current, and clamping voltage. The breakdown voltage of the device, also known as the ‘Clamping Voltage’, is the voltage at which current will start to flow through the diode. This is also the voltage at which the device will limit the voltage across the load, and protect against any over voltage transients. The MXLSMLJ20CAE3 has a breakdown voltage of 20 V.The peak pulse current of the device is the maximum amount of current that can run through it before it starts to malfunction. The peak pulse current of this device is 6A. The peak pulse reverse path power dissipation is the amount of power that the device can absorb before it starts to malfunction. The peak pulse reverse path power dissipation of the device is 150W. The leakage current of the device is the amount of current that can flow through it when no external voltage is applied. The leakage current of the MXLSMLJ20CAE3 is typically less than 1 μA.The clamping voltage of the device is the voltage at which the device will limit the voltage across the load, and protect against any over voltage transients. The clamping voltage of this device is 10 V.All of these factors combine to make the MXLSMLJ20CAE3 an excellent protection device. It is able to provide low leakage current, which is important for low power applications, while also providing high energy capability, and excellent clamping voltage protection. The device is able to limit the voltage across the load, while still providing adequate protection against over voltage transients. This makes it an ideal protection device for a variety of applications, such as cellular phones, notebook PCs, PDAs, and medical equipment.
