Additional Details

The SRDA05-4 TVS diode array provides four channels of ESD protection. It uses a silicon avalanche diode technology to clamp transient voltages to a safe level. The low clamping voltage protects sensitive components from overvoltage stress. The fast response time ensures that transient events are suppressed quickly. The small package size allows for use in space-constrained applications. The operating temperature range is typically -40°C to +125°C. It is commonly used to protect I/O ports and data lines from ESD and other transient events.
