The onsemi 1SMA18AT3 is a transient voltage suppressor (TVS) diode designed for robust protection in demanding applications. This unidirectional device, housed in a compact SMA (DO-214AC) package, offers a nominal reverse standoff voltage of 18V. It features a peak pulse current capability of 13.7A (10/1000µs) and a maximum clamping voltage of 29.2V at this current. With a peak pulse power rating of 400W, the 1SMA18AT3 provides efficient protection against voltage transients. Its low capacitance of 645pF at 1MHz makes it suitable for general-purpose applications where signal integrity is critical. The operating temperature range of -65°C to 150°C (TJ) ensures reliable performance across a wide spectrum of environmental conditions. This component is commonly utilized in automotive, industrial, and consumer electronics for overvoltage protection.
