Additional Details:

The P651P3100SARP is typically available in a surface-mount package, allowing for easy integration into PCB designs. Key parameters include the breakover voltage (VBO), holding current (IH), and surge current rating (ITSM). These parameters should be carefully considered when selecting this SIDACtor for a specific application. The breakover voltage determines the voltage level at which the device begins to conduct, while the holding current specifies the minimum current required to maintain conduction. The surge current rating indicates the maximum surge current that the device can withstand without failure. Littelfuse SIDACtor devices are designed to provide robust and reliable overvoltage protection in a wide range of applications, contributing to the overall reliability and longevity of electronic equipment.
