TVS (transient voltage suppression) diodes are used to protect electronic systems and components from high-energy, trans-electrical events such as electrostatic discharge (ESD) or over-voltage transients. The SM6T68A-E3/52 series of TVS diodes from Panasonic are particularly well-suited for ESD applications due to their low clamping voltage, ultra-low capacitance and high surge current capability.

Application Field of the SM6T68A-E3/52

The SM6T68A-E3/52 series of TVS diodes from Panasonic are ideally suited for use in ESD protection applications. It provides protection from ESD pulses of up to 25kV (HBM Model). This is due to its very low, 5.8V clamping voltage and ultra-low capacitance of 0.4pF. As a result, it can effectively protect sensitive electronic components from ESD events without causing any significant signal degradation. The SM6T68A-E3/52 is also capable of handling up to 59A surge current, making it ideal for use in high-current applications. Additionally, its small case size of 0805 makes it easy to use in space-constrained environments.

Working Principle of the SM6T68A-E3/52

In principle, TVS diodes work by clamping the transient voltage to a safe level, thus protecting sensitive electronics. The SM6T68A-E3/52 achieves this by using a series of specially designed semiconductor structures. When a high voltage transient is applied, the device reacts instantly, clamping the voltage to the device\'s breakdown voltage. The device can then dissipate this energy without causing any permanent damage to the surrounding electronics. Additionally, the device has a low capacitance, which allows it to recover quickly from transient events and prevents signal degradation.

Conclusion

The SM6T68A-E3/52 series of TVS diodes from Panasonic is an ideal solution for ESD protection applications due to its low clamping voltage, ultra-low capacitance and high surge current capability. It can effectively protect sensitive electronics from ESD events without causing significant signal degradation. Additionally, its small case size makes it ideal for use in space-constrained environments.
