C650-180-WH

Overview

The Bourns C650-180-WH is a Transient Blocking Unit (TBU) device designed for high-speed circuit protection. It functions as a solid-state, bidirectional switch that blocks transient overvoltages while allowing normal operating currents to pass. The component utilizes a unique semiconductor structure to provide rapid response times and robust surge handling capabilities without the degradation associated with traditional fuses or varistors.

Feature Summary

• Bidirectional switching capability for AC and DC applications
• High-speed transient blocking response
• Solid-state construction ensuring long-term reliability

Applications

• Industrial equipment surge protection
• Telecommunication line protection
• Automotive electronic circuit safeguarding

Procurement Notes

Verify the specific datasheet version corresponding to the C650-180-WH designation to confirm exact voltage ratings and package dimensions. Ensure compatibility with the intended thermal management requirements and mounting process. Cross-reference with official Bourns documentation to validate material declarations and compliance status before integration into final designs.

Selection Notes

Select this component when fast-acting, non-degrading protection is required for sensitive electronics. Consider its bidirectional nature for AC lines and its ability to handle high peak currents without latching. Evaluate the specific voltage threshold requirements against the system's maximum allowable transient levels to ensure adequate protection margins.

Part Context

This part belongs to the C650 series of TBU devices from Bourns Electronic Solutions. These components are engineered to replace traditional protective elements like gas discharge tubes or polymeric PPTCs in applications demanding faster response times and higher cycle life. The series is widely used in environments requiring robust immunity to electrical overstress events.

Replacement Considerations

Direct substitutes include other parts within the C650 and C850 series families, such as the C650-260-WH or C850-180-WH, depending on specific voltage rating needs. Verify pinout compatibility and thermal characteristics when replacing legacy protection devices with TBU technology.
