Additional Details:

The SGT3100SCT is available in a small SOT-23 package, making it easy to integrate into existing designs. Its low capacitance and low clamping voltage are critical for protecting sensitive circuits from damage caused by electrostatic discharge and other transient voltage events. The device is designed to meet or exceed industry standards for ESD protection, ensuring that it can withstand the harsh conditions found in many electronic applications. Its low leakage current contributes to overall system power efficiency. The SGT3100SCT effectively diverts transient overvoltage events away from the protected circuit, clamping the voltage to a safe level. This prevents damage to sensitive components and helps to maintain the overall reliability of the system.

The specific trigger voltage, clamping voltage, and capacitance values will vary depending on the specific model and application. Refer to the Littelfuse datasheet for detailed specifications.
