Introduction

The SMC5K30A-M3/H is a compact and shock-resistant TVS – diode with a wide array of applications. It is used for transient peak voltage suppression in a range of electronic products, from consumer electronics to automotive components and industrial equipment. The multi-layered diode is housed in a 3-pin MiniSMD package, which is designed to be integrated into systems with limited space and provide easy installation.

Application Field

The SMC5K30A-M3/H is designed specifically for transient voltage protection, offering up to 30A peak pulse current and a breakdown voltage of 5.3V, with excellent over-voltage protection capabilities. This makes it ideal for a range of uses, from protecting communication lines, providing insulation and ESD protection in mobile devices, to protecting power supply lines and other sensitive components in automotive and industrial electronics.

The SMC5K30A-M3/H also exhibits excellent circuit reliability and endurance during high-temperature operation, making it possible to use in harsh environments. This makes it well-suited for use in security systems, surveillance equipment, home automation, medical equipment, and robotics, as well as heavy electrical and mechanical equipment.

Working Principle

The core feature of the SMC5K30A-M3/H is its Shock Protection Diode (SPD) design, which is based on avalanche breakdown. This diode works by allowing a current to be conducted through its highly doped junction until the avalanche breakdown voltage is reached and the diode turns into a “Zener” mode. When the current flow exceeds the diode’s peak forward current, the diode rapidly switches back to a non-conductive state and limits the current flow, resulting in a steady voltage gain across the diode.

In order to ensure maximum protection capability, the SMC5K30A-M3/H is designed to handle transient voltage peaks up to 5.3V. The SPD also offers excellent clamping and response time with its low capacitance, making it more suitable for high-speed communication interfaces. Additionally, the low capacitance also helps to reduce power consumption.

The various components of the diode are designed to allow for different levels of over-voltage protection. For instance, the internal ESD protection circuitry of the diode can help to reduce the damaging effects of electrostatic discharge. Similarly, the SMC5K30A-M3/H diode comes with a surge protector that protects from larger transient voltage surges.

Conclusion

The SMC5K30A-M3/H is a high-performance and shock-resistant TVS – diode offering up to 30A peak pulse current and a breakdown voltage of 5.3V. Its unique combination of features makes it a suitable solution for a range of applications, from consumer electronics to industrial and automotive components. Additionally, its SPD design and over-voltage protection capabilities make it perfect for applications requiring robust protection against extreme voltage transients.
