TVS (Transient Voltage Suppressor) diodes are a form of protection device designed to limit the surge voltage passed through a circuit, acting as both a capacitor and a conductor. The SMDA03C-4-2E3/TR7 diode is an example of a unidirectional TVS diode designed to provide protection against transient overvoltages. It has a breakdown voltage range of between 33 and 36 volts, and is designed for applications requiring absolute maximum ratings of 35 volts.

Application Field

The SMDA03C-4-2E3/TR7 is suitable for use in a range of applications including computers, networking equipment and consumer electronics. It is used to protect electrical circuits from overvoltage, as well as prevent surges which can damage sensitive components and degrade performance. It can be used to protect a variety of components, such as communication IC’s and modules, transistors, fuse as well as piezoelectric and ceramic discrete components.

Working Principle

The SMDA03C-4-2E3/TR7 diode is designed to suppress ESD (electrostatic discharge) and other voltage surges in the range of 33 to 36 volts. This means that when an excess electrical surge is applied to the circuit, the diode will trigger and limit the peak voltage level exposure. The protection is typically achieved by the diode either absorbing or dissipating the surge, or both, as the application requires.

The diode has a low breakdown voltage with a maximum value of 36 volts, and this determines the peak voltage at which the protection will begin to take effect. The device is manufactured with an ESD protection element that allows it to absorb ESD pulses of up to 15KV without breakdown.

The diode is designed with an optimum power dissipation characteristic which ensures it can withstand frequent overvoltage events while still providing a high level of protection. This feature enables the device to absorb the surges and prevent damage to the connected components.

The SMDA03C-4-2E3/TR7 diode is also designed to provide overvoltage protection for multiple devices, meaning that all of the connected components are protected from the same overvoltage. This ensures that the circuit is safe from any overvoltage events.

Conclusion

The SMDA03C-4-2E3/TR7 diode is a unidirectional TVS diode designed to protect circuits from transient overvoltages. It has a breakdown voltage range of between 33 and 36 volts, and is designed for applications requiring absolute maximum ratings of 35 volts. The diode is suitable for use in a range of applications, including computer and networking equipment and consumer electronics, and it can provide overvoltage protection for multiple components and devices. It is designed with an optimal power dissipation characteristic, enabling it to absorb surges and protect connected components from overvoltage damage.
