The MAX3982UTE+T is a high-speed differential ESD and EMI protection transistor array that provides differential line-to-line protection against electrostatic and electromagnetic interference. It is primarily used in single-ended and differential high-speed digital and analog signals in automotive, industrial, and medical applications. The device is optimized to optimize overall power dissipation by providing ESD and EMI protection while maintaining high-speed performance.

The MAX3982UTE+T application field and working principle are suitable for providing differential line-to-line protection for high-speed, single-ended and differential signals. The part has two channels and each channel designed for ESD, EMI, and surge protection. The MAX3982UTE+T has a PNP transistor with high gain, providing high attenuation of ESD and EMI signals across the line. The high gain of the PNP transistor reduces the capacitance between the two channels, allowing the device to maintain high data rate performance while providing optimal ESD and EMI protection.

The MAX3982UTE+T application field and working principle are based on two different principles. The first principle is a low EMI path that relies on low-capacitance PNP and NPN transistors. The PNP transistor allows for high gain, providing high attenuation of ESD and EMI signals to the line. The NPN transistor has high impedance and low current so it can provide a low-impedance path for signal transmission. The second principle is a high ESD path that relies on a differential-mode clamping circuit to protect against ESD events. This circuit includes two N-channel MOSFETs connected in series, which creates a high voltage drop across the circuit and helps protect against ESD events.

The MAX3982UTE+T is suitable for high-speed applications such as automotive buses, CAN, Ethernet, PCI Express, SAS/SATA, LVDS, and M-LVDS. It can be used in low-voltage, high-speed, single-ended and differential signal protection applications. Its combination of power efficient design and ESD/EMI protection make it suitable for automotive, industrial, and medical applications.

The MAX3982UTE+T is easy to use and provides an efficient solution for ESD and EMI protection. It is an ideal solution for those applications that require high-speed, low-voltage protection. The device is designed to provide the highest possible protection without compromising the performance of the signal.
