The BSPD400240D3P is a mixed technology TVS (Threshold Voltage Suppressor) used as an electrostatic discharge (ESD), electrical fast transients (EFT) and surge protection device for signal protection applications. The device combines two technologies, a thyristor and transistor architecture, in order to benefit from the best features of each technology in order to provide superior protection and a wider protection range.

The device has a low clamping voltage, which allows it to be used in high-speed signal lines. It also has an internal low impedance structure that offers better signal integrity compared with other TVS technologies.The BSPD400240D3P has an ultra-low capacitance that helps to reduce signal degradation on high-speed data lines. In addition, its patented Self-Offset-Voltage (SOV) technology enables the device to reset itself after an ESD event and helps to ensure long-term reliability.

The device features an ESD voltage level of up to 25 kV and an EFT voltage level of up to 40 A. It also offers excellent current handling capability up to 10 A and very fast response time. Furthermore, it has an operating voltage range from 4 to 20 V with guaranteed clamping voltage up to 40 V. It is available in a variety of packages, including SOIC, advanced leadless packages, pluggable packages, and SMD DIP packages.

The working principle of BSPD400240D3P TVS is based on the thyristor and transistor architecture. The device combines both thyristor and transistor components, allowing it to take advantage of the best features of both technologies. The device has two options of ESD protection - the thyristor network provides the fast response of an ESD event, while the transistor network provides sustained current protection for fast transients. The device is designed to provide short-circuit protection and low clamping voltage, preventing overvoltage damage to the components connected to it.

The BSPD400240D3P is mainly used in signal protection applications such as consumer electronics, computers, telecommunications, automotive, industrial and medical devices. It is also suitable for use in USB ports, SCSI ports, JTAG ports, HDMI ports, and other ports that are used to transmit high speed signals. The device provides effective protection against ESD, EFT, and surge events, ensuring reliable operation.
