Transient Voltage Suppressors (TVS) – also known as Transient Voltage Surge Suppressors (TVSS) – are designed to reduce the voltage of an electrical surge or transient current that is beyond the normal operating level. TVSs are designed to improve device reliability and reduce the level of electrical interference that is created by the surge. There are a wide variety of TVS devices available to protect power electronics, such as MOVs, Zener diodes, and the SACB30.

The SACB30 is a uni-directional transient voltage suppressor (TVS) diode. It is designed to protect voltage sensitive components from transient surges of high electrical current. The SACB30 is suitable for a variety of applications, such as automotive, industrial, telecommunications, and consumer electronics. The device has an ultra-low capacitance of 4 pF and is capable of handling a peak power rating of 300 Watts.

The SACB30 has a wide operating range with a minimum breakdown voltage of 6.0V and a maximum reverse standoff voltage of 9.0V. It also has a high surge current rating of 40A. This makes it ideal for protecting components that are sensitive to voltage transients, such as power electronic components, microprocessors, and other integrated circuits.

The working principle of the SACB30 is simple and effective. When a voltage transient of more than the device’s rated breakdown voltage is present, an avalanche breakdown occurs at the PN junction. This triggers the device to start conducting, which effectively clamps the transient voltage below the SACB30’s breakdown voltage. This prevents any damage to the voltage sensitive components that are connected to the device.

The SACB30 is also designed to be highly reliable. It is capable of withstanding multiple ESD pulses and has a thermal shutdown feature that will shut off the device if the junction temperature is exceeded. This helps to protect the device from damage caused by external voltage transients.

The SACB30 is an ideal solution for applications that require protection from voltage transients. It is a highly reliable device that is designed to provide efficient and effective protection from transient electrical surges. The device is also well-suited for a variety of applications, such as automotive, industrial, telecommunications, and consumer electronics applications.
