Additional Details

The PJSD03W typically features a low standoff voltage (e.g., 3.3V) suitable for protecting low-voltage circuits. It is available in an ultra-small surface-mount package such as DFN1006 or similar. Key electrical characteristics include its peak pulse power, clamping voltage at specific pulse currents, and reverse leakage current. The specific values for these parameters depend on the exact part number variation and should be verified in the datasheet. The low capacitance is crucial for protecting high-speed data lines without degrading signal integrity. The device is designed to meet industry standards for ESD and surge immunity. The operating temperature range is generally -55°C to +125°C.
