TVS - Diodes

A TVS (Transient Voltage Suppressor) diode is a device designed to protect circuitry from damage due to electrical transients such as electrical surges, electrostatic discharge, and inductive switching. A TVS diode is a voltage-dependent semiconductor device that offers protection from voltage spikes and is generally used in electronic devices such as computers, telecommunication systems, and power conversion circuits. The SMDA24C-4/TR13 is a TVS diode designed to provide over-voltage surge protection and reduce electromagnetic interference (EMI) to protect electronic equipment.

Application Field

The SMDA24C-4/TR13 TVS diode is a unidirectional device designed for use in low voltage (<30V) AC and DC power systems. It is especially useful for suppressing transients on Ethernet, DSL, USB, and UL-1459 power line applications. The SMDA24C-4/TR13 provides a competitive edge by providing bidirectional protection with minimal dissipation. It also provides fast, effective, and cost-effective protection of wideband digital communications lines against ESD and electrical transients.The SMDA24C-4/TR13 stands out from its competitors in providing industrial-grade surge suppression for data and telecommunications systems. Its UL rating makes it suitable for use in industrial environments, such as industrial parks, and in field-installed environments, such as Fixed Wireless Access (FWA) sites.

Working Principle

The SMDA24C-4/TR13 is designed to dissipate transient energy that would otherwise cause irreversible damage to electronic equipment. It works in a very simple and straightforward manner. When an over-voltage transient event is detected, the device automatically reduces the transient voltage by “clamping” it. This is done by passing the excess voltage through a series of diodes, which act as a surge protection device. The diodes have a predetermined voltage threshold at which they will begin to conduct current, allowing the device to redirect the surge voltage into an alternative safe path. This effectively reduces the damage caused by the over-voltage transient.When constructing a circuit with the SMDA24C-4/TR13, the design engineer can choose between two types of peak current derating. The first is a “zero reverse recovery” configuration, which is best for applications that require low output voltage switchings, such as power supply circuits. The second is a “positive reverse recovery” configuration, which is better for applications that require a higher output voltage switchings, such as DC-to-DC converters. In addition to derating the peak current, the SMDA24C-4/TR13 also has outstanding temperature derating, allowing it to perform even better in high-temperature environments. The device is extremely low in cost, and its size makes it perfect for space-critical applications.

Conclusion

The SMDA24C-4/TR13 TVS diode is an ideal surge protection device for low voltage (<30V) AC and DC power systems, and Ethernet, DSL, USB, and UL-1459 power lines. Its small size and cost make it perfect for space-critical applications, and it comes with two configuration options (zero and positive reverse recovery) for applications with different voltage requirements. Its UL rating makes it suitable for use in industrial and field-installed environments, providing industrial-standard surge suppression and effective protection against ESD and electrical transients.
