SMTAK3-058C Circuit Protection

TVS - Diodes are devices utilised for protection against abnormal transient voltages. SMT2K3-058C is such a device that can be used for protecting sensitive components from over-voltages by clamping the transient signal. These devices are typically used in mobile electronic devices, high speed data transceivers, power supplies, automotive infotainment systems, and industrial and medical electronic equipment.

The SMT2K3-058C is an ultra-low capacitance TVS diode with an ESD protection of greater than 25kV. It is a silicon avalanche diode with a low capacitance body diode, which can protect up to 15kV transient events with a reverse leakage current of less than 10μA. It is a small, low-profile device, with a thickness of 1.2mm and is designed to fit small surface mount applications.

The working principle of SMT2K3-058C is to protect the equipment from overvoltage event. When a transient event occurs, the diode will turn on and divert the transient current away from the protected circuit. Depending on the transient voltage, the current that passes through this device will be limited by its reverse working voltage and the given dynamic resistance. The dynamic resistance will be inversely proportional to the current passing through the diode. When the transient ends, the device switches off and the load is again in operation.

In order to be used in an optimal manner, the SMT2K3-058C needs to be well matched with the application, and the voltage and current ratings should be taken into account. It is also important to consider the dynamic resistance, since this affects the ability of the diode to dissipate the transient voltage. It is also important to consider the capacitance of the device as this affects the protection of the circuit.

In conclusion, SMT2K3-058C is a great choice for protecting circuits and component from transient overvoltage events. It is low capacitance, low profile, and high ESD protection. It can protect up to 15kV transients with a reverse leakage current of only 10μA. By following proper capacitance and voltage matching techniques, the SMT2K3-058C can provide optimal protection for any given application.
