TVS - Diodes

A transient voltage suppressor (TVS) diode is a passive component that is designed to provide protection from over-voltage transients, also known as electrical spikes or surges. This device plays an important role in the reliability and performance of electronic systems. It is designed to protect sensitive electronic components from wide range of transients – from fast rising surges to more time-extended high-energy pulses, and is usually installed in the power and data line.

SMB10J11HE3/5B

The SMB10J11HE3/5B is a unidirectional Transient Voltage Suppressor (TVS) diode specifically designed to protect against fast transients. These TVS devices have very low reverse standoff voltage and low leakage current, making them ideal for protecting sensitive parts from voltage spikes. The device features an integrated ESD diode for Electrostatic Discharge (ESD) protection. The ESD diode acts as a short circuit during times of high voltage, and the integrated ESD protection ensures that the TVS diode is not damaged by sudden voltage spikes.

Application Field

SMB10J11HE3/5B TVS diodes are typically used in automotive, industrial, consumer, telecommunications, and medical electronics for over-voltage and ESD protection. This device is well suited for protecting circuits against voltage transients within an extended temperature range. It is ideal for data-sensitive applications such as communication systems, computer networks, industrial controls, and process monitoring.

Working Principle

The SMB10J11HE3/5B TVS diode works by diverting current spikes away from sensitive components, protecting them from voltage transients and ESD events. As the transient voltage increases to the breakdown voltage, the device turns on and starts diverting the current to the cathode, avoiding any dangerous voltage or current spikes from reaching the device. Once the voltage drops below the breakdown voltage, the diode returns to its normal "off" state, allowing the current to continue on its normal path.

The device is also able to limit the current to safe levels and clamp the voltage to prevent damage to vulnerable components in the system. It is important to note that the SMB10J11HE3/5B has a low clamping voltage and a short clamping time, making it suitable for capturing fast-rising ESD spikes. Furthermore, the high surge capability of the device makes it an effective over-voltage protection solution.

Conclusion

The SMB10J11HE3/5B is a unidirectional TVS diode specifically designed to protect against fast transients and ESD events. The device offers an integrated ESD diode for enhanced protection from voltage spikes, and features a low reverse standoff voltage and low leakage current for reliable over-voltage protection. SMB10J11HE3/5B TVS diode applications include automotive, industrial, consumer, telecommunications and medical electronics. The device’s ability to clamp the voltage quickly and safely makes it a highly effective over-voltage protection solution.
