TVS diodes are an important component that is used to protect electronics from voltage transients due to overvoltage transients. The SA40CA-E3/54 is a type of TVS diode designed specifically for high-speed signal applications. It has a low voltage clamping level, and the small size make the device ideal for applications in mobile phones and other small electronics.

Application Field

The SA40CA-E3/54 TVS diode is an ideal solution for protecting high-speed signals. These signals are susceptible to damage from overvoltage transients due to the amount of power that is transferred over them. The SA40CA-E3/54 TVS diode can help prevent this damage by clamping the voltage to a safe level. This helps protect the signal from any damage that may be caused by electrical surges.

The device has been designed to be used in high-speed signal applications such as computer motherboards, network equipment, and other devices that require a lot of data to be transferred across them. It can also be used in mobile phones and other small electronics like tablets. The small size of the device allows for easy integration into smaller spaces, which is ideal for mobile devices. Its low voltage clamping level makes it suitable for protecting delicate integrated circuits.

Working Principle

The SA40CA-E3/54 uses a combination of diode-type subunits to clamp each line to a safe voltage. This is done by connecting a diode between each line and ground. When the line fluctuates above the device’s impedance, the diode will conduct and create a low resistance path to ground, thus clamping the voltage to a safe level. This helps prevent damage to the line due to electrical surges.

The SA40CA-E3/54 TVS diode also features reverse absorption, which helps reduce the power of the surge upon a direct hit. It has an ESD protection capability of up to 25kV, which helps protect delicate circuits from damage due to electrostatic discharge. Furthermore, the device is RoHS compliant, meaning it is designed to meet international requirements for environmental safety.

Conclusion

The SA40CA-E3/54 from Alpha & Omega Semiconductor is an ideal solution for protecting high-speed signals from overvoltage transients. It offers a low voltage clamping level and reverse absorption capabilities to help reduce the power of a surge when it hits. It also has a high ESD protection capability of up to 25kV and it is RoHS compliant. Its small size makes it ideal for small electronics, such as mobile phones, as well as other applications in need of protection from voltage transients.
