Additional Details

The PESD3V3L5UY,115 features a very low capacitance, which is crucial for protecting high-speed data lines without significantly affecting signal integrity. It provides a low clamping voltage, limiting the voltage seen by the protected circuitry during an ESD event. Key electrical parameters include the reverse standoff voltage, the breakdown voltage, the dynamic resistance, and the clamping voltage. Consult the datasheet for precise values and test conditions. The AEC-Q101 qualification ensures its suitability for demanding automotive applications. The small SOT-883 package is ideal for surface-mount assembly.

When selecting an ESD protection diode, it's crucial to consider the data rate of the protected signal, the ESD threat level, and the allowable capacitance. The PESD3V3L5UY,115 offers a high level of protection with minimal impact on signal performance.
