TVS-diodes are becoming increasingly popular in a variety of applications, from automotive to industrial, due to their ability to withstand large outputs of electrostatic discharge (ESD) or electrical over-stress (EOS). The SA28CA B0G is a popular transient voltage suppressor (TVS) diode which is used to protect sensitive electronics from high voltage surges. It is also used to reduce interference from external voltage sources and reduce power supply noise. In this article, we will discuss the application field and working principle of the SA28CA B0G.

Application Field

The SA28CA B0G is a bidirectional diode which can be used to protect electronic systems and components from high voltage pulses and transients. It is suitable for use in any application, including automotive, industrial, consumer electronics, communication equipment, and many others. The SA28CA B0G is a popular choice for automotive applications because it is low-cost, efficient, and reliable. The device has an extended experience of protection in a variety of automotive conditions.

The SA28CA B0G can also be used in industrial applications to reduce Power Supply Noise. The device is commonly used in conjunction with other ESD/EOS protection devices to provide additional protection from high voltage surges. This is particularly important in industrial applications where high voltages can be generated from static electricity, cable discharge events, and power supply noise.

The SA28CA B0G is also suitable for use in consumer electronics devices, including sound cards, DVD players, and other devices where electric interference can occur. The device provides protection from damage caused by ESD/EOS events as well as reduce power supply noise. This is particularly important in consumer electronics where low cost reliability is a must.

Working Principle

The SA28CA B0G is a bidirectional diode which employs zener breakdown technology. When a high voltage pulse or surge is applied to the device, the diode passes the surge current to ground and dissipates the energy by entering its zener breakdown region. This protects the connected electronics from damage caused by the surge.

The SA28CA B0G also has a wide operating temperature range and fast clamping response, which means it can react quickly to high voltage surges and protect the connected circuits from damage. The device also has a low dynamic resistance and low leakage current.

The device is also highly reliable and has a long life. It has been tested in extremely harsh conditions and proven that it can work reliably even after exposure to temperatures of up to 125°C. This makes it an ideal choice for industrial and automotive applications where reliability is critical.

Conclusion

The SA28CA B0G bidirectional diode is a popular TVS-diode used to protect sensitive electronics from high voltage pulses and transients. The device is suitable for use in a wide range of applications, from automotive to consumer electronics. It has a wide operating temperature range, fast clamping response, low dynamic resistance, low leakage current, and long life. This makes it a reliable and cost-effective choice for many applications.
