Technical Specifications

The KDS193-RTK typically has a standoff voltage of around 3.3V and a clamping voltage of approximately 6.0V at a peak pulse current. It's available in a small SMD package, such as SOT-23. The specific surge capability depends on the pulse waveform and duration, but it's designed to handle significant transient events. It's crucial to consult the official KEC datasheet for precise electrical characteristics, surge current ratings, and thermal resistance values to ensure it meets the specific application requirements. Operating temperature ranges from -40°C to +125°C. Reverse leakage current is very low at the standoff voltage. This TVS diode is particularly effective in safeguarding circuits against ESD events as per IEC 61000-4-2 standards and against surge events compliant with IEC 61000-4-5. It's a silicon-based device designed for high-reliability applications. This device is commonly used where board space is at a premium and robust ESD/surge protection is needed.
