TVS – Diodes are electronic components that help protect circuits and other components from power related damage caused by over-voltage or electrostatic discharge. The SMBG130A-M3/52 is a type of TVS – diode that can provide exceptional transient protection along with good thermal performance. It is well suited for industrial and automotive applications due to its excellent surge immunity characteristics. Below is an overview of the application field and working principle of SMBG130A-M3/52.

Application Field

The SMBG130A-M3/52 is a fast response, low power, unidirectional TVS – diode suitable for industrial and automotive applications. The TVS diodes offer superior ESD performance of up to 10kV, making them the perfect choice for applications where transient protection and surge immunity are a critical concern. They can also be used as clamping devices for transient and incoming surge protection in automotive and other industrial applications. The SMBG130A-M3/52 can also be used as a return diode to protect the power supply from over-voltage conditions.

The SMBG130A-M3/52 also provides unparalleled EMI/RFI Protection, protecting systems from the potentially damaging electromagnetic radiation generated during operation. It also offers low leakage current and stable operation over a wide temperature range of -40°C to +125°C. This makes it suitable for automotive, industrial and consumer applications.

Working Principle

The SMBG130A-M3/52 is an unidirectional TVS diode, meaning it can only pass currents flowing in one direction. It is composed of two layers – an N-type semiconductor layer and a P-type layer. The N-type material is more insulating, while the P-type material is slightly more conductive. When a positive surge of voltage is applied to the P-type material, it quickly becomes conductive, allowing the current to pass through and thus protecting the circuit from damage.

The SMBG130A-M3/52’s fast response time enables it to react quickly when exposed to over-voltage and other power related risks. Its low capacitance, combined with its low power dissipation, ensures that it won’t affect the normal operation of the circuit. The diode has been designed to protect circuits from transient voltages up to 10kV, making it suitable for use in high voltage applications.

The SMBG130A-M3/52 is designed to be mounted on a printed circuit board for maximum effect. The diode is able to dissipate a large amount of energy (up to 1.2J) in the shortest possible time, thus providing superior protection to the host circuit.

Conclusion

The SMBG130A-M3/52 is a fast response, low power, unidirectional TVS – diode suitable for industrial and automotive applications. It is able to provide superior protection from over-voltage and ESD related risks. The diode is also capable of dissipating a large amount of energy in a short duration of time, making it an excellent choice for use in high voltage applications. Its superior EMI/RFI protection and wide temperature range also ensure that it delivers long lasting performance.
