TVS - Diodes: MXLSMCJLCE14AE3

TVS - diodes, also referred to as transient voltage suppressors, are semiconductor devices used to protect other electronic components from sudden surges of voltage that exceed a specified ratings limit. This type of diode is designed for high-frequency transients and is selected based on the voltage rating and the amount of energy it can absorb. The MXLSMCJLCE14AE3 is a bidirectional diode that is commonly used in automotive and industrial applications.

Application Field

The MXLSMCJLCE14AE3 TVS diode is designed for over-voltage protection in automotive and industrial applications. It is manufactured with a SOT-23 package which makes it ideal for systems with limited board space. Its bidirectional design makes it suitable for both AC and DC applications, such as in AC mains surge protection and in automotive power supply and command units. The device also has low capacitance values, making it a great choice for high-speed devices and applications with signal integrity requirements. It can be used on any point where over-voltage protection is needed, and it is also available with other features including a lower capacitance, and higher peak pulse current ratings up to 16A.

Working Principle

When the voltage in an application increases beyond its operating limit, the TVS diode will quickly clamp the voltage down to a safe level. This is done by the two back-to-back zener diodes connected in a common cathode configuration which creates a junction region in the device. When the voltage rises, this junction region begins to conduct current which will clamp the voltage down. This protection works for both AC and DC voltages, and it is sensitive enough to detect voltage transients that happen very quickly.

The MXLSMCJLCE14AE3 TVS diode can operate up to 1000V, making it suitable for most standard applications. It also has a fast response time of less than 1 nanosecond, making it suitable for applications that need sub-nanosecond protection from transients. The device always has an adequate amount of energy absorption capacity, allowing it to absorb more energy than most standard TVS diodes.

Conclusion

The MXLSMCJLCE14AE3 TVS diode is an ideal choice for applications needing over-voltage protection. Its compact form factor makes it suitable for limited board space, and its bidirectional design allows it to be used in AC and DC applications. The device is also designed to provide a fast response time to transients and has a high pulse current and energy absorption rating. It’s a great choice for automotive and industrial applications needing reliable over-voltage protection.
