TVS-Diodes: SMDJ20CA R7G Application Field and Working Principle

TVS - Diodes play an important role in industry, technology and power electronics. As such, they are the most popular components in various electronic circuit designs. TVS-diodes, a type of transient voltage suppression (TVS) diode, are semiconductor components with wide-range applications, including over-voltage protection, power line surge protection, data line surge protection, circuit isolation, circuit disconnection, and circuit spike protection.

The SMDJ20CA R7G TVS diode is a Silicon Avalanche Diode (SAD) with a wide operating range. It is designed to protect sensitive electronic components from high transient voltages commonly found in automotive and industrial environments. This diode offers a high breakdown voltage, fast switching time and excellent electrical efficiency. Furthermore, it can withstand reverse voltage up to 20V DC.

Applications of SMDJ20CA R7G TVS Diode

The SMDJ20CA R7G is designed for use in multiple applications including:

  • Overvoltage protection in automotive, power line, industrial and consumer electronic devices
  • Surge protection for communication lines
  • Circuit isolation in isolated power supplies
  • Circuit disconnection in switching power supplies
  • Spike protection for power and control lines

The device is capable of providing high-performance protection when exposed to over-voltage, over-current, over-temperature and other electrical and environmental stresses. It could effectively protect connected devices such as AC/DC converters, sensors, computers, data acquisition systems, monitoring systems and other signal processing equipment.

Working Principle of SMDJ20CA R7G TVS Diode

TVS diodes use a form of overvoltage protection called the avalanche breakdown to protect sensitive circuit components from overvoltage by ‘clipping’ overvoltage pulses. When a excessive voltage is applied across the TVS diode, the built-in reverse bias voltage exceeds the avalanche breakdown voltage, allowing the diode to conduct in both directions. This process then causes a large amount of current to flow, clamping the voltage to the TVS breakdown voltage and providing an instantaneous protection to the connected circuit.

The SMDJ20CA R7G TVS diode has a maximum peak pulse current rating of 8.3A, and a maximum safe operating voltage rating of 30V. This high surge current capability is achieved by virtue of its low forward voltage and the fact that it features a shielded Zener diode network which ensures a low forward voltage drop and a fast response. Additionally, a patented anti-parallel diode structure is integrated into the SMDJ20CA R7G, providing alternative protection against both positive and negative spikes.

Conclusion

In conclusion, the SMDJ20CA R7G TVS Diode is a versatile, high-performance device designed for a wide range of applications. It provides excellent protection against transient voltage spikes while maintaining a low forward voltage drop, and a fast response time. This device is capable of providing transient voltage protection at up to 20V DC, making it ideal for protecting sensitive circuit components in a variety of automotive and industrial environments.
