SMBJ6.5CE3/TR13

The SMBJ6.5CE3/TR13 is a discrete signal protection device specifically designed to protect sensitive electronics from overvoltage transients. It is a type of high-voltage unidirectional transient voltage suppressor diode, otherwise known as a TVS diode, which works by quickly clamping the voltage to a safe level, preventing damage to the protected circuits and devices.

Application

The SMBJ6.5CE3/TR13 is an ideal solution for overvoltage and overcurrent protection in automotive, telecom, consumer product and industrial applications. It is commonly used in automotive and other mobile appliances as a protection device against electrical transients such as electrostatic discharge (ESD), lightning strikes, and power surges. It has also become the preferred choice of components used in telecom applications, due to its superior surge current handling capability and low thermal resistance. In consumer product applications, the SMBJ6.5CE3/TR13 is used for circuit protection in a variety of open, or exposed, electronic systems, such as industrial control units, navigation systems, and portable equipment.

Working Principle

The TVS diode is designed to clamp the voltage at a safe level whenever a surge or transient voltage occurs, by providing a low impedance path for the transient current. TVS diodes are fabricated with structures similar to those used in rectifier diodes, but are designed to protect against transients that have higher current or higher impulse energy. Such transient impulses can be caused by electrostatic discharge (ESD), electrical fast transients (EFT), or lightning, all of which can potentially damage circuit components. When the transient voltage is higher than the TVS diode ratings, an avalanche breakdown occurs and the device clamps the voltage to a level within the safe operating region of the protected device.

The SMBJ6.5CE3/TR13 is designed to provide excellent ESD protection, with excellent surge current handling capabilities. It features a built-in high-frequency optimization capacitance for better ESD performance, and its low leakage current and fast response time make it well suited for a variety of applications. The TVS diode is rated for a peak pulse power of 1.5kW, and can withstand a pulse peak current of 11A.

Conclusion
