TVS - Diodes

Transient Voltage Suppression (TVS) diodes are components used in electronic circuits to protect vulnerable parts from transient overvoltage. The SMAJ130CA-13-F is a uni-directional TVS diode with a wide working voltage range, which makes it a suitable choice for a variety of applications.

Application Field and Working Principle

The SMAJ130CA-13-F TVS diode has a working voltage range of 5-220V, which makes it applicable in a wide range of power supply circuits, in particular for protecting against voltage spikes. A voltage spike originates from outside sources, such as power grids or ESD, and can damage sensitive components in the circuit. The SMAJ130CA-13-F is designed to absorb these spikes, dissipating their energy and preventing damage to other components.

The diode’s working principle is simple. When the diode is exposed to a high voltage, it becomes conductive and discharges the excess voltage to a safe, low-voltage point. The TVS diode does this quickly and effectively, with a response time of around 5 ns, making it suitable for a variety of applications. The diode is also equipped with a wide operating temperature, making it suitable for both high- and low-temperature environments.

Features and Benefits

The SMAJ130CA-13-F provides several features and benefits, such as low leakage current and a low capacitance to ensure a fast response time. It is also designed to withstand high surge currents and is compliant with multiple standards, such as RoHS and ESD. Additionally, it also has an integrated ESD protection, allowing it to protect against electro-static charge.

It provides a low clamping voltage and offers a low dynamic resistance, allowing it to absorb high surge currents. This makes it well-suited for automotive and industrial applications where overvoltage protection is critical for the device’s safety.

Conclusion

The SMAJ130CA-13-F TVS diode is a suitable choice for power supply circuits which require higher protection levels. Its wide working voltage range, low forward voltage drop and fast response time make it ideal for a variety of applications. Furthermore, its integrated ESD protection and low capacitance enable it to cope with transient overvoltage and provide reliable protection.
