TVS (transient voltage suppression) diodes, also called surge stopper diodes, are the most common type of surge protector. They have been widely used in circuit boards to protect against transient voltages caused by lightning, static electricity, electrical noise, and other transient signals. SACB26 diodes are a type of TVS diode that is used in high-power applications. In this article, we will discuss the application field and working principle of SACB26 diodes.

Application Field Of SACB26 Diodes

SACB26 diodes are designed to provide protection for high-power circuits that are subject to large voltage spikes (transients). This makes them ideal for use in applications such as solar energy, power supplies, and military and aerospace applications. They can also be used to protect sensitive electronic components from damage due to high voltage transients, as well as provide protection against electromagnetic interference (EMI).

Working Principle Of SACB26 Diodes

The working principle of SACB26 diodes is based on their ability to conduct current in one direction only. When a voltage spike is applied to the diode, it will only allow current to flow in the reverse direction, away from the device it is protecting. This is done by creating a potential barrier that prevents current from flowing in the forward direction. This potential barrier, known as the reverse breakdown voltage, is what makes SACB26 diodes more effective than other types of TVS in high-power applications.

The reverse breakdown voltage of a SACB26 diode is typically in the range of 5-20 volts, which is higher than other types of TVS diodes. The larger the reverse breakdown voltage, the greater the surge protection provided to the circuit. As the voltage spike passes through the diode, it will be dissipated as heat, thus protecting the sensitive electronic components in the circuit. The reverse breakdown voltage of a SACB26 diode also makes it resistant to thermal runaway, which is a common problem with other types of surge protectors.

Conclusion

SACB26 diodes are designed to provide protection for high power circuits that are subject to large voltage spikes (transients). They have a larger reverse breakdown voltage than other types of TVS diodes, which makes them ideal for use in applications such as solar energy, power supplies, and military and aerospace applications. When a voltage spike is applied to the diode, the potential barrier created by the reverse breakdown voltage prevents current from flowing in the forward direction, thus protecting the sensitive electronic components in the circuit from damage.
