TVS - Diodes: SMCG6.5A-HRA Application Field and Working Principle

Transient Voltage Suppressive (TVS) diodes are an essential component for many applications where sudden and unexpected surge in voltage needs to be blocked to protect the connected devices. TVS diodes are widely used for protecting general consumer and medical equipment, and industrial automation and control systems from damage caused by overvoltage and electrical transients. SMCG6.5A-HRA is a TVS diode specifically designed to provide protection from power transients and overvoltage conditions.

Application Field of SMCG6.5A-HRA

SMCG6.5A-HRA has wide application fields because it can provide protection against both over-current and over-voltage conditions, as well as from surges and transients. It can be used in industrial applications, such as power supplies and other industrial equipment, in aviation and military applications, and in consumer applications such as medical devices, TVs, and computers.

SMCG6.5A-HRA is also suitable for automotive applications because of its environmental resistance and 100% tested burn-in performance. It can replace any existing SMC type of components in circuits with its same high reliable protection against transients.

Working Principle

SMCG6.5A-HRA uses a single junction diode to provide protection from electrical transients and over-voltage conditions. It works by clamping transients to a certain voltage level, which depends on the breakdown voltage of the diode. This breakdown voltage is typically adjustable between 5.5 V and 11 V. The diode provides a low impedance path to divert the over-voltage away from connected devices.

The SMCG6.5A-HRA also has an integrated crowbar circuit. This is triggered when the diode detects inrush/surge currents higher than a certain set point. This helps to protect the connected devices from the effects of over-voltage conditions. The device can also be used in conjunction with other components like PTCs (Positive Temperature Coefficients) and MOVs (Metal Oxide Varistors) to provide additional protection against power transients.

SMCG6.5A-HRA can work both in integrated form and as a discrete component. Standard SMC packages are available, which makes installation and replacement of the device easier. The device can be mounted on a heatsink to dissipate heat and maintain an optimal working temperature.

Conclusion

SMCG6.5A-HRA is a high-performance TVS diode designed to protect circuits from overvoltage and power transients. It can be used for various industrial, automotive, and consumer applications. The device has an adjustable breakdown voltage and an integrated crowbar circuit, making it suitable for even harsher environments. It is available in a variety of standard packages, making installation and replacement easy.
