TVS (Transient Voltage Suppressors) are a type of diode that is used to protect electronic circuits from transient events such as Electro Static Discharge (ESD) or electrical surges. This type of protection is critical for a number of applications where damage to sensitive components can occur. The STMicroelectronics MAPLAD130KP275CA diode, commonly referred to as a TVS, is a robust and reliable protection solution for ESD, electrical surge, and overvoltage protection.

Overview of the MAPLAD130KP275CA TVS

The MAPLAD130KP275CA diode is a Transient Voltage Surge Suppressor designed by STMicroelectronics specifically for automotive applications. The device helps protect against electrostatic discharge, electrical surges, and overvoltage conditions. It is designed with a low internal capacitance of 2.7pF to ensure minimal signal distortion on the output side of the protection circuit. Additionally, the device has a high surge rating of 160W at 8/20µs for automotive applications.

The diode is designed with a low voltage drop, low leakage current, and low capacitance to minimize energy losses and signal distortion. The device is made with a two-layer Ni/Au construction to ensure a reliable solder joint and superior environmental resistance. The diode also has an operating temperature range from -55 to 150°C, which ensures it can withstand temperature extremes in the automotive environment.

Application Fields and Working Principle of the MAPLAD130KP275CA TVS

MAPLAD130KP275CA TVS diodes are commonly used in a wide range of automotive applications to protect against ESD, electrical surges, and overvoltage conditions. Such applications include, but are not limited to, headlight and bumper protection, ECU/ECM protection, powertrain control, and airbag control. Additionally, the MACLAD130KP275CA TVS diode is also designed for use in HVAC, refrigeration, electric vehicle, and industrial equipment applications.

The basic working principle of a MAPLAD130KP275CA TVS diode is to provide protection by redirecting excess current away from the protected circuit, into a safe path. When an overvoltage condition occurs, the diode conducts a large, controlled, current away from the protected system. This helps protect the protected system from the potentially damaging overvoltage, and the TVS diode will then return to its open circuit state when the overvoltage is gone.

The MAPLAD130KP275CA diode also has a low capacitance of 2.7pF, which helps reduce any signal distortion on the protected side, while ensuring that the diode can absorb the current spike quickly. The low voltage drop and low leakage current of the device also helps reduce energy losses while providing a reliable protection solution in a wide range of automotive and industrial environments.

Conclusion

The MAPLAD130KP275CA TVS diode is a reliable and robust protection solution for ESD, electrical surge, and overvoltage conditions commonly found in a wide range of automotive and industrial applications. The device has a low capacitance of 2.7pF and a high surge rating of 160W at 8/20µs, making it an ideal solution for providing protection in harsh automotive and industrial environments.
