TVS (Transient Voltage Suppressor) diodes are power semiconductor devices used to protect sensitive electronic circuits from over-voltage conditions caused by environmental and electrical disturbances such as electrostatic discharge (ESD) and lightning surges. The SACB18 is a Bidirectional TVS Diode Array (commonly referred to as a Diode Array) designed to protect sensitive electronic components from high voltage transients, such as ESD, lightning, and other over-voltage conditions. The SACB18 is a state-of-the-art, low-voltage bidirectional Transient Voltage Suppressor Diode Array, designed to protect sensitive electronic components from high voltage transients. It combines high-speed protection (less than 0.7ns response time) with low reverse-bias leakage current, making it ideal for a wide range of applications from high-end consumer electronics to automotive and industrial electronics.

The SACB18 diode array is designed to clamp 4 lines simultaneously, and provides a maximum clamping voltage of 18V in forward biasing directions (V+ & V-). The SACB18 offers superior ESD protection (±15kV on Human Body Model), surge protection (10A 10/1000µs on 4-Line Draft) and pulse current protection. It is available in 16-pin flat SMT package, and is compliant with RoHS, AECQ and Pb-Free requirements.

The working principle of the SACB18 diode array is based on the principle of zener breakdown. When a pulse of voltage is applied over the specified reverse breakdown rating, the diode array starts to conduct current. This current is limited and clamped at a level determined by the zener voltage of the reverse breakdown voltage of the device and the series resistance. In this way, the SACB18 can offer excellent protection against various ESD and surge events.

The SACB18 array has several key features and benefits that make it ideal for various applications. To begin with, its clamped voltage is very low (18V), which makes it suitable for modern electronic components that require very low voltage protection. Furthermore, its fast response time (less than 0.7ns) is ideal for high-speed applications such as USB, HDMI, and Ethernet. It also offers low reverse-bias leakage current, which makes it suitable for a wide range of applications such as consumer electronics, automotive, and industrial electronics.

The SACB18 array is an ideal solution for a variety of applications that require protection against high voltage transients. It is suitable for use in high-end consumer electronics, automotive, and industrial electronics. Its low clamping voltage, fast response time, and low leakage current make it ideal for a wide range of applications. The SACB18 is RoHS, AECQ and Pb-Free compliant, and is available in a 16-pin flat SMT package.
