TVS (Transient Voltage Suppressor) diodes are clamped voltage devices which are designed to protect electronic components from voltage spikes of up to thousands of volts. These devices usually take the form of a low leakage diode, which can be used to limit current, or a 4-terminal (2 anode/2-cathode) device. TVS diodes perform the role of a spark gap by allowing a transient surge of current to pass, while clamping any voltage which exceeds its breakdown voltage such that the voltage applied to the protected device is limited to a safe level. Many applications require a specific TVS diode, such as the 5.0SMDJ75CA.

The 5.0SMDJ75CA is a bidirectional unidirectional TVS diode featuring a breakdown voltage of 7.5V. It is designed to absorb surge currents up to 250A, allowing for the protection of sensitive circuits from electrical overstress due to voltage transient events. The device is ideal for lower power applications, as it has a relatively low power dissipation of 200mW. Its reverse-standoff voltage of 5.0V, together with its low capacitance, make it well-suited for protection of data and signal lines with up to 100MHz operating frequencies.

The primary application for the 5.0SMDJ75CA is in the protection of Circuit boards and other electronic devices. The device has a relatively low leakage and can prevent voltage spikes of up to 7.5V. It can also be used in applications which require current limiting, as it offers a low internal resistance. When the device is switched on, it will absorb any overvoltage above the breakdown voltage and limit the voltage at the protected device to a safe level. This allows for the protection of even the most sensitive components.

The 5.0SMDJ75CA\'s working principle is based on the Zener diode. A Zener diode is a diode which acts as a voltage regulator, allowing current to flow in either direction when a certain voltage (the breakdown voltage) is reached. In the 5.0SMDJ75CA, this breakdown voltage is set at 7.5V, and when the voltage exceeds this level the diode will start to conduct. This allows the device to limit the voltage across the protected circuit or component, preventing damage due to excessive voltage.

The 5.0 SMDJ75CA is a versatile device, offering protection from electrical overstress, across both low power and high voltage circuits. Resistive and capacitive loads, as well as multiple data and signal lines can be protected with this device, allowing for the protection of sensitive components from voltage transients. Its low power dissipation makes it well-suited for use in low power applications, while its breakdown voltage of 7.5V makes it ideal for use in applications which require voltage protection up to this level.
