TVS - Diodes: SZP6SMB24AT3G application field and working principle

TVS-diodes are specialized diodes designed to protect vulnerable circuits from high voltages. TVS stands for transient voltage suppressor, and these devices are used both to limit destructive spikes and to clamp them to safe levels. The SZP6SMB24AT3G is an example of a popular TVS-diode.

Applications

The SZP6SMB24AT3G is typically used in automotive, consumer electronics, and industrial applications. Its main purpose is to provide protection for vulnerable components in electrical equipment that may be damaged or destroyed if they are subjected to excessive voltages. It can be used to protect against surges, ESD (electrostatic discharge), inductive load switching, and lightning strikes. It is also commonly used in power supplies, data lines, and telecommunication equipment.

Working Principle

TVS diodes work by clamping the voltage when it exceeds a certain level. When voltage exceeds the reverse breakdown voltage of the diode, it begins to conduct current, diverting the voltage away from the protected components. The SZP6SMB24AT3G has a breakdown voltage of 24 volts and can handle up to 6 amps of current. This allows it to protect sensitive components from high-voltage signals without damaging them.

When there is no over-voltage, the SZP6SMB24AT3G acts like an open circuit, meaning that it is effectively disconnected from the circuit and does not affect the normal operation of the system. When the voltage rises above 24 volts, however, the diode conducts current, diverting the excess voltage away from the circuit and limiting the voltage to a safe level. The SZP6SMB24AT3G is also designed to withstand high energy spikes without failing or causing false triggers, meaning that it can provide reliable protection.

Conclusion

TVS diodes, such as the SZP6SMB24AT3G, are an important tool for protecting circuits and components from over-voltage. They are used in many different types of applications, from automotive to consumer electronics. They operate by clamping the voltage when it exceeds a certain level, diverting the excess voltage away from the circuit and limiting the voltage to a safe level. While they are not the only form of protection available, TVS-diodes are an effective and reliable solution for many applications.
