MXLP4KE22AE3 Circuit Protection

TVS diodes are components designed to provide electrical protection against overvoltage. Their conductive structure and voltage clamping action make them efficient elements that can limit overvoltage events, while still allowing a normal operating current to pass. The MXLP4KE22AE3 TVS - diode is specifically designed for high up-times in direct current applications, including automotive applications.

Features

• Low leakage current of 5nA
• Double Line design for maximum power absorption
• Low Stand-off voltage of 6.8V
• Maximum peak pulse power of 1.2kW

Application Field

The MXLP4KE22AE3 TVS - Diode is designed for applications that require protection from overvoltage and high up-times, such as automotive electronics. These diodes are also ideal for consumer electronics, telecommunications, and agricultural electronics. The diode’s double-line design make it a good choice for direct current protection in automotive applications.

Working Principle

TVS diodes function by controlling current flow and clamping voltage during an overvoltage event. When the overvoltage cause of the event exceeds the breakdown voltage of the TVS diode, it acts as a short circuit, thereby protecting the device from further damage. This short-circuiting action keeps a situation from becoming worse until the overvoltage event passes.

The internal structure of the MXLP4KE22AE3 creates two conductive paths to higher levels of voltage ratings. This double-line structure allows the diode to safely absorb large amounts of power and redirect it away from the protected electronic component, protecting it from further damage.

Conclusion

The MXLP4KE22AE3 TVS - Diode is designed to protect automotive electronics from overvoltage damage. Its low leakage current, low stand-off voltage, and double-line structure make it an ideal choice for direct current applications, while its 1.2kW peak power rating offers protection from even the most powerful surges. The diode functions by clamping the voltage during an overvoltage event, before redirecting the surge away from the protected component, ensuring its survival.
