SMCJ400E3/TR13 Application Field and Working Principle

The SMCJ400E3/TR13, or surface mount transient voltage suppressor (TVS) diode, is designed to protect sensitive electronic equipment from voltage spikes and transients. It is an ideal choice for use in portable and other devices that are exposed to voltage transients created by sources such as electrostatic discharge (ESD), lightning, and electrical surges.

Application Field

The SMCJ400E3/TR13 is one of the most common types of diode used for transient voltage suppressor purposes, due to its wide operating range and excellent transients absorption capability. Its application fields include consumer electronics, computers, telecommunications, industrial control systems, as well as other electronic devices that are subject to voltage transients.

The SMCJ400E3/TR13 is also an effective device in preventing overvoltage, as it contains built-in Zener diode that instantly switches on and off to limit peak voltage and cycling alert during transients to prevent damage. Furthermore, the SMCJ400E3/TR13 features superior ESD and surge protection, which makes it suitable for providing reliable protection against external ESD energy. The low capacitance of the product means that it can be used in a wide array of high frequency applications.

Working Principle

The working principle of the SMCJ400E3/TR13 is based on a three-terminal Zener-diode circuit. When there is a chance of a voltage transient or surge, the Zener diode triggers and switches on, instantly reducing the voltage across the device. The device quickly reacts to any kind of sharp voltage changes in the circuit and limits the voltage surge. The device can accept and dissipate several kinds of waves including sine, half sine, spike shape, and flat top.

The SMCJ400E3/TR13 also features breakdown voltage capability from 400V to 700V. This range of breakdown voltage ensures that the circuit is protected even in case of a high-voltage transient. Moreover, the SMCJ400E3/TR13’s fast response eliminates any risk of overshoots that may cause damage, providing lightning-fast protection from voltage transients.

Apart from operating voltage, the SMCJ400E3/TR13 is also easy to install, thanks to its ultra mini-package design. It is also lead-free, meaning that it has no solder containing lead, making it ‘green’ and environment-friendly.

Conclusion

The SMCJ400E3/TR13 is an ideal choice of diode for providing high-performance transient voltage surge protection. It is a great choice for applications ranging from consumer electronics and communications to industrial control systems, due to its superior voltage protection capability, fast response, and wide operating range.
