SMCJ6038E3/TR13 Application Field

SMCJ6038E3/TR13 is a TVS (Transient Voltage Suppressor) device that is used with many applications, mainly for ESD (electrostatic discharge) protection in telecom, datacom, and industrial applications. This device is especially helpful when high-power levels of ESD are encountered and when multiple ESD protection circuits are required within one system. The SMCJ6038E3/TR13 diode provides a very high-power level protection compared to other types of TVS devices.

The SMCJ6038E3/TR13 can also be used in applications with extremely short transient durations, such as Ethernet backplane systems. The very fast response time of the SMCJ6038E3/TR13 diode is ideal for these applications. Additionally, this diode can be used in power line applications, as it is designed to provide lightning and over-voltage protection.

Working Principle

At the heart of the SMCJ6038E3/TR13 TVS-Diode is a Zener diode which acts to protect the circuit from damage if a high voltage transient or surge is present. The Zener diode performs this function by shorting the current out of the circuit; this prevents any over-voltage being caused by the transient.

The SMCJ6038E3/TR13 has an internal television surge suppression element that acts as a voltage clamp. This element behaves like a zener diode, and it is designed to bring the voltage at the input of the diode to a maximum of 13.4V when a surge is present. This prevents any damage that may be caused by a surge.

The SMCJ6038E3/TR13 also has an integrated fuse that is designed to open if the diode is exposed to a long duration surge. This prevents any additional damage which may result from a sustained over-voltage situation.

Conclusion

The SMCJ6038E3/TR13 TVS diode is an essential part of protecting circuits from damage due to ESD, lightning, and over-voltage situations. It has a fast response time, and its built-in fuse and bi-directional damping make it an excellent choice for high-power ESD protection in telecom, datacom, and industrial applications.
