MASMCJ110CA

TVS – Diodes have been used for a long time to protect sensitive electronics from high voltage incidents due to lightning strikes and transients in the power lines. The MASMCJ110CA is a Unidirectional Transient Voltage Suppressor (TVS) specifically designed to protect in-vehicle electronics from damage due to electrostatic discharge (ESD). The device is ideal for protecting circuits from voltage transients caused by ESD. This application field and working principle of the MASMCJ110CA will now be discussed.

Application Field

The MASMCJ110CA is designed to protect sensitive in-vehicle electronics against electrostatic discharge. This type of TVS diode is suitable for automotive battery line protection, can provide up to 10 kV ESD protection, and greatly reduce the voltage damage caused by ESD. Furthermore, its low leak current (<500 nA) helps to protect against overvoltage andE overcurrent conditions, while its low capacitance (<3 pF) helps to reduce reflections. In addition, the device also has built-in circuit protection, which can reverse the risk of short circuit damage.

Working Principle

The MASMCJ110CA uses a unique supplemental breakdown technology to protect sensitive in-vehicle electronics against ESD transients. The device consists of two MOS-controlled thyristors connected in butterfly configuration (MTD). MTD technology provides very fast response times, allowing the device to sense and suppress very high voltage transients in a fraction of a microsecond. When triggered, the device also provides a direct connection between the power supply and a low-power path, limiting the current flowing through the circuit.

The device also features a built-in electro-mechanic latch (EML) mechanism. This mechanism provides dual protection against high voltage events, ESD and over-current hazards. The EML acts as a mechanical switch that is turned on and off by an electro-mechanical force generated when the voltage exceeds a certain limit. This limits the current flowing through the circuit, thus providing additional protection.

The device also includes an isolation dielectric material (VDM) which prevents cross talk and shorts. This material also reduces the resistance of the device while maintaining a low capacitance, allowing for improved current conduction capability. Furthermore, the device has a low thermal resistance, allowing it to operate in both hot and cold climates. This helps to ensure reliable operation in any environment.

Conclusion

The MASMCJ110CA is a Unidirectional Transient Voltage Suppressor specifically designed to protect in-vehicle electronics from high voltage events due to electrostatic discharge (ESD). The device incorporates several features such as a built-in circuit protection and MTD technology for providing fast response times, as well as an EML mechanism for additional protection. In addition, the device also has a low thermal resistance and VDM to reduce cross talk and shorts. The MASMCJ110CA is ideal for protect automotive circuits from voltage transients caused by ESD.
