Introduction

The SMBJ7.5CA-13 is an unidirectional bi-directional device that shows excellent clamping performance in the telecom market. It is generally applied in applications such as surge protection, communication circuits, computer peripheral circuits, and other electronic circuits. The device is ideal for all voltages up to 7.5V. It has low leakage current and low capacitance, making it one of the best components that is used in telecom applications.

Application Field

The device was specifically designed for use in the Telecom industry. It is mainly used in applications such as surge protection, communication circuits, and computer peripheral circuits. The device can provide superior voltage clamping and prevent overvoltage damages to the surrounding electronic components. It can also provide high-speed transient suppression that is suitable for digital waveforms. In addition to the Telecom industry, the device can also be used in consumer electronics. It can be used in all kinds of Notebooks, PC’s, Monitors, Smartphones, and Tablets. It is also commonly used in digital video surveillance equipment and home automation systems.

Working Principle

The SMBJ7.5CA-13 is a unidirectional, bi-directional device. It operates on a closed loop principle that works to protect against high-frequency and high-voltage transients that may damage nearby electronic components. In operation, the device works in two stages. The first stage detects when an overvoltage occurs and the second stage clamps the overvoltage in a matter of nanoseconds. This is done by first detecting the overvoltage and then by conducting the overvoltage to a low impedance level. The device uses a reverse recovery time, or snubber, to provide maximum transient voltage clamping capability. This also includes a low capacitance design that can reduce ringing and EMI.

Conclusion

The SMBJ7.5CA-13 is a unidirectional, bi-directional device that is specially designed for use in the Telecom industry. It is mainly used to protect against high-frequency, high-voltage transients and can provide superior voltage protection for surrounding components. It is also suitable for use in consumer electronics, digital video surveillance equipment, and home automation systems. The device works on a closed loop principle and uses a reverse recovery time to provide maximum transient voltage clamping capabilities.
