SA11CHE3/54

A Transient Voltage Suppressor (TVS) diode is an electronic device designed to protect a system against voltage transients. SMA11CHE3/54 is a specific type of TVS diode, designed to protect semiconductor components from overvoltage transients. It has a capacitance of 11pF (typical) and a clamping voltage of 13.9 V.

The SMA11CHE3/54 is designed to absorb transient overvoltages without sustaining permanent damage. It is designed to be used in systems in which a low capacitance is necessary, such as Ethernet or USB systems. The SMA11CHE3/54 has an average clamping voltage of around 13.9 V, which makes it suitable for high-speed differential signal interfaces.

The working principle of the SMA11CHE3/54 is based on the PN junction diode in which an abrupt change in voltage is induced by reverse bias. This occurs when a voltage higher than the forward voltage rating of the diode is applied across the diode. The diode then starts to act as a voltage protection device.

The SMA11CHE3/54 is well suited for applications in which transient voltages must be absorbed without causing damage to sensitive electronic components. It can be used to protect RS232, USB, Ethernet, and other high-speed differential signal interfaces. This device is also suitable for applications in automotive and industrial electronic systems.

The SMA11CHE3/54 has a reverse standoff voltage of 13.9 V, which allows it to clamp transients up to an equal magnitude in both directions. This device has a high surge current rating of 8A, which makes it suitable for high-current applications. It is also able to dissipate a power rating of up to 0.5W.

The SMA11CHE3/54 is also designed to be relatively low in capacitance, which makes it ideal for use in high-speed applications. It has a leakage current rating of 20μA (maximum), which ensures that the device will not interfere with the signal integrity of the applications.

In conclusion, the SMA11CHE3/54 is a specific type of Transient Voltage Suppressor (TVS) diode designed to absorb voltage transients without sustaining permanent damage. It is suitable for use in applications in which transient protection is necessary and a low capacitance is required, such as Ethernet and USB systems. It has a reverse standoff voltage of 13.9 V and can dissipate up to 0.5W. The low capacitance and high surge current ratings make this device suitable for use in high-speed and high-current applications.
