SA51CAHE3/73 is a TVS Diode of ITM (Intelligent Transient Modulator) family. The device is a three-pin surface mount diode for transient suppression applications. It has an ultralow capacitance of 3-pF and an ultra low-clamping voltage of 73V. The SA51CAHE3/73 offers one of the lowest capacitance and breakdown voltage ratings compared to other TVS diodes, which makes it suitable for applications which have very strict space requirements and high frequency performance.

The working principle of the SA51CAHE3/73 is that it serves as a transient avoidance component on high-speed data bus lines. It is able to absorb and shunt any potential transients to provide protection against electrostatic discharges (ESD) or any low current transients, up to a maximum reverse peak power of 500W. Its ability to provide superior performance without compromising signal integrity or generating too much heat makes it suitable for a variety of high speed board to board or cable to board applications where very high signal integrity is essential.

The SA51CAHE3/73 can be used in a variety of applications. It can be used in Ethernet, Fibre-Channel, USB, Firewire, Serial ATA, and PCI Express applications. Additionally, it can also be used in LCD displays, portable storage, and digital imaging devices.

The SA51CAHE3/73 is particularly well-suited for high-speed applications which require superior performance and protection for bidirectional signal lines and for data lines which operate at high speeds with low voltage, such as USB and Firewire. In addition, it has an operating temperature range of -55°C to +125°C, which makes it suitable for a wide range of applications.

In summary, the SA51CAHE3/73 is a TVS diode with a very low capacitance and breakdown voltage rating, making it suitable for applications where high speed performance and signal integrity are essential. It is also able to provide superior protection against ESD and other low current transients, up to a maximum reverse peak power of 500W. It is well-suited for a wide range of applications, including Ethernet, Fibre-Channel, USB, Firewire, Serial ATA, and PCI Express applications. Its operating temperature range of -55°C to +125°C makes it suitable for a variety of temperature ranges.
