TVS diodes are solid-state semiconductor devices used as over-voltage protection and to provide surge protection for electronic devices in various applications. The SMDJ100A-T7 is one of the most widely used TVS diodes in the industry, suitable for high-speed data transmission and current source protection applications. In this article, we will discuss the application fields of SMDJ100A-T7 and its working principle.

Application fields of SMDJ100A-T7

The SMDJ100A-T7 can be used to protect electronic products from the damages caused by over-volt this includes transient over-voltage effects like electrostatic discharge (ESD), electrical fast transients (EFT), surges, inductive load switching and so on. SMDJ100A-T7 is also suitable for back-to-back application. This TVS diode has an avalanche breakdown characteristic and is able to withstand 5kV, 8/20 μs pulse current, making it ideal for protecting sensitive electronic components. It is also suitable for high-speed signal transmission systems, such as HDMI, USB, Ethernet, S-Video, component video and other digital applications.

The SMDJ100A-T7 is used in applications such as consumer andindustrial electronics, automotive electronics, telecom systems, professional audio, LCD displays, computer electronics, smart cards, and power modules. Additionally, due to its small size, the SMDJ100A-T7 is ideal for SMD-style designs.

Working Principle of SMDJ100A-T7

The SMDJ100A-T7 is an unidirectional diode that is able to step up the voltage submitted to the device during surge protection. It operates by using a reverse breakdown voltage which triggers the conduction of the diode. When the input current exceeds the breakdown current, the diode conducts and the excess energy is dissipated.

The SMDJ100A-T7 is an extremely fast device, with a typical response time of only 5 nanoseconds. It also has a very high surge capability, able to handle surge currents of up to 12.5A without breaks. Furthermore, it has a very low clamping ratio, ensuring protection of the device and the equipment it’s connected to.

An important advantage of the SMDJ100A-T7 is its ability to sustain high di/dt and dv/dt rates, making it suitable for applications requiring fast data transfer rates. Additionally, it has a very low leakage current, making it suitable for use in low power applications. It is also RoHS compliant, making it even more attractive for applications demanding high levels of quality.

Conclusion

The SMDJ100A-T7 is a versatile TVS diode that provides reliable protection from transient over-voltages. It is suitable for high-speed data transmission applications, has an extremely fast response time, and a very high surge capability. It is an ideal choice for applications that demand protection and reliability.
