TVS - Diodes

Transient Voltage Suppressors (TVS) diodes are devices that are used to protect electrical circuits from harmful ESD, EFT, and lightning strikes. This article discusses the application field and working principle of the MA1.5KE6.8CA TVS diode.

Application Field

MA1.5KE6.8CA transient voltage suppressors are designed for protection against Electrostatic Discharge (ESD) and for low-level overvoltage protection. In particular, they are used to protect high-speed data lines such as USB 2.0, CAN bus, and other high speed differential lines. They can also be used in automotive, industrial, telecom, and consumer electronics applications.

Working Principle

MA1.5KE6.8CA TVS diodes are designed to protect sensitive electronic components from high surge and ESD protection. The device is able to conduct excessive voltages up to 6.8 V, and when the voltage across the TVS diode exceeds the avalanche breakdown voltage, it will start conducting current and protect the circuit or device from ESD and overvoltage surge.

For low level ESD protection, MA1.5KE6.8CA TVS diodes have a lower breakdown voltage so they can protect against level 2 and level 3 ESD pulse waveform voltages. They can also protect against surge events up to 500 V due to their high peak pulse power rating. The diode is also able to withstand reverse transients up to 16 V.

Conclusion

MA1.5KE6.8CA TVS diodes are designed to protect sensitive electronics from Electrostatic Discharge (ESD) and low-level overvoltage protection. The device is able to conduct excessive voltages up to 6.8 V, and when the voltage exceeds the avalanche breakdown voltage, it will start conducting and protect the circuit or device from ESD and overvoltage surge. This device is suitable for use in automotive, industrial, telecom, and consumer electronics applications.
