TVS - Diodes

TVS diodes are used in many applications as protection against electrical transients, such as those that can occur during power up events or lightning strikes. MLCE64AE3 is a surface mount transient voltage suppression (TVS) diode designed to protect two signal/power lines against transients from 6V up to 65V. This device is available in a 2-pin SOT-23 package.

Application Fields

MLCE64AE3 is designed for applications such as telecommunications, computing, industrial, and consumer. It is suitable for transient voltage protection for signal and power rails, and can be used in a wide variety of electronic systems including networking, automotive, medical and other consumer electronics.

Working Principle

MLCE64AE3 TVS diode is a silicon avalanche diode which can quickly react to high voltages and surge currents. When a transient voltage, such as a lightning strike, is applied to the two signal lines, the MLCE64AE3 will respond by clamping the voltage to a lower level, limiting the high-voltage transient. The diode is able to withstand transient peak reverse power dissipation of up to 255 watts.

The MLCE64AE3 can also act as a shunt regulator by providing a low voltage drop across the device, allowing longer line difficulties in applications where line loss is an issue. This device is designed with excellent peak surge capability, and can operate up to 18A for 8/20µs. In addition, the non-linear clamping characteristic makes it a perfect choice for protection against overvoltage transients. The MLCE64AE3 is fully compliant with the requirements of UL60950, CSA22.2 No. 234 & EN61347 for electrical safety.

Conclusion

In conclusion, the MLCE64AE3 TVS diode is a reliable and cost-effective choice for protection against overvoltage transients across two signal/power lines. Its peak surge capability and non-linear clamping make it ideal for applications where line loss is an issue. This device is fully compliant with relevant safety regulations, making it a safe and reliable choice for protecting sensitive electronics.
