SA20CAHR0G Circuit Protection

TVS - Diodes - SA20CAHR0G application field and working principle

TVS - Diodes are specific semiconductor components used in electronic devices to protect them from damage caused by voltage, such as high-voltage discharges in lightning or electro-static discharges (ESD). They are mostly used in the automotive, consumer electronics, telecommunications, and industrial equipment industries.

The SA20CAHR0G is a surface mount unidirectional TVS - Diode manufactured by Panasonic. It is designed to protect electrical components and circuits against transients caused by lightning strikes, electrical static discharges, high voltages, and other forms of waveforms. It provides protection from ultra-fast transients, with low clamping voltage of 6.5V, low operating voltage of 6.0V, and fast transient response time of 5ns. It is specified for an operating temperature range of -55°C to +125°C.

The principle of operation of the SA20CAHR0G TVS - Diode is very simple. When the voltage across it exceeds its breakdown voltage, the diode will conduct current in proportion to the excess voltage. This sudden flow of current generates a surge of energy that can be either dissipated or absorbed by the diode, whichever is necessary to protect the electrical component or circuit. The diode also has a reverse voltage protection structure, so it prevents reverse current flow in the case of a reverse voltage.

The main application fields of the SA20CAHR0G TVS - Diode are circuit protection, electromagnetic interference (EMI) filtering, and surge protection. It is used in wide variety of applications, including automotive, consumer electronics, telecommunications, and industrial equipment. It is suitable for ESD protection in automotive electronics, as well as for overvoltage protection in consumer electronics and industrial equipment.

In summary, the SA20CAHR0G TVS - Diode is a surface mount unidirectional diode that provides high-quality protection for electronic components and circuits from transients caused by high voltages, lightning strikes, ESD, and other lightning related events. It has fast transient response time of 5ns, low clamping and operating voltages, and is specified for an operating temperature range of -55°C to +125°C. The main application fields are circuit protection, EMI filtering, and surge protection.
