Additional Details:

The SRDA3.3-6 is designed to protect up to six lines. It features a typical breakdown voltage of around 3.6V and a clamping voltage of approximately 6V during a surge event. Its low capacitance (typically less than 1 pF) ensures minimal signal degradation in high-speed data transmission lines. The device is compliant with industry standards for ESD protection (e.g., IEC 61000-4-2) and EFT protection (e.g., IEC 61000-4-4). It is available in a small surface-mount package, such as an SOT-23-6 or similar, making it easy to incorporate into compact designs. The operating temperature range is typically from -40°C to +125°C. This TVS diode array is widely used in consumer electronics, industrial equipment, and automotive systems to protect sensitive electronic components from damage due to transient voltage events, improving overall system robustness and reliability.
