The SI8402DB-T1-E1 part from Vishay is an integrated circuit (IC) designed for multistage overvoltage protection. It is a robust and low-cost solution for protecting devices from high voltage surges, spikes, and short-circuit events. It is available in a SOIC-8 package and features a breakdown trigger voltage of 12V, a clamping voltage of 44V, a response time of 10ns or less, and a thermal shutdown of 160°C. It also features overvoltage protection of -20V to +22V, reverse battery protection of -22V to +26V, and overcurrent protection of up to 6A. The device is suitable for automotive applications, LCD monitor, DC/DC converters, and other general applications.
