A semiconductor device that protects sensitive electronics from voltage spikes and transients by clamping excess voltage to safe levels.
A Transient Voltage Suppressor (TVS) is a specialized electronic component designed to protect circuits from sudden, brief overvoltage events such as electrostatic discharge (ESD), lightning-induced surges, and inductive load switching transients. It operates by rapidly diverting excess current away from protected components when voltage exceeds a predetermined threshold, typically responding within picoseconds to nanoseconds to prevent damage to integrated circuits, sensors, and other sensitive devices.

这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
TVS devices are silicon-based with faster response times (nanoseconds) and precise clamping, ideal for sensitive electronics. MOVs (Metal Oxide Varistors) are ceramic-based, slower, and degrade over repeated surges, better for high-energy applications.
Choose based on working voltage (VRWM above circuit voltage), clamping voltage (VCL below device max rating), peak pulse current (IPP for expected transients), and package size. Consider bidirectional TVS for AC lines.
