Without protection circuits, small electronic devices would be destroyed by voltage spikes caused by the turning on and off of large motors, lightning strikes, and other events. TVS diodes, also known as transient voltage suppressors, are unidirectional devices that offer protection against these voltage spikes. The SMBF13A-TR is a popular type of TVS diode that is used in a variety of electronic devices.

Overview

The SMBF13A-TR is a unidirectional TVS diode configuration with a voltage clamping value of 13V. It is a surface-mount mini-flat device made of Bi-Directional Transient Voltage Suppression technology. It has two leads, with the cathode connected to the flat recess at the top of the package. The lead frame of the device is approximately 0.3mm thick and plated for better heat conduction.

Application Fields

The SMBF13A-TR is used for line-to-ground applications, as well as non-IEC-1000 surge applications in various electronic devices, including portable computers, monitors, printers, hard drives, and data storage devices. It is also suitable for use in mobile phones, satellites, telecom systems, and other equipment with high-speed data links.

Working Principle

The SMBF13A-TR works by using its two diodes in series to create a zener protection path. When a voltage spike is detected, the diode will conduct and the voltage across the diode will be clamped to a safe level. This prevents the overvoltage from reaching the circuitry and causing damage. The device can handle up to 5.0A of surge current for 8/20μs waveforms.

Advantages

The SMBF13A-TR offers a number of advantages over other transient voltage suppressors. It has a very low forward voltage and a fast response time, allowing it to respond quickly to transient voltage events. It can also operate over a wide temperature range of -55°C to +125°C, making it suitable for a variety of applications. The device is also RoHS compliant, making it environmentally friendly.

Conclusion

The SMBF13A-TR is a popular TVS diode that is used in a variety of electronic devices. It provides protection against voltage spikes and can handle up to 5.0A of surge current. It has a low forward voltage and a fast response time, and it can operate over a wide temperature range. Additionally, it is RoHS compliant. The SMBF13A-TR is an effective and efficient TVS diode for many applications.
