Procurement Notes

Verify the specific part number against official Bourns documentation to confirm the dual bi-directional topology and 850V/50mA ratings. Ensure the 6-pin DFN package matches the design requirements. Confirm UL compliance status and operating temperature range specifications directly from the manufacturer's datasheet before finalizing procurement decisions.

Selection Notes

Select this component when dual-channel bidirectional protection is required for high-voltage interfaces up to 850V. The 50mA rating suits applications with lower current demands. The DFN form factor supports automated assembly and space-constrained designs. Validate thermal performance and electrical characteristics against the target application's surge profiles.

Part Context

This device belongs to the TBU High-Speed Protectors series by Bourns. These protectors are engineered for rapid response to transient events, safeguarding sensitive electronics in communication and data transmission systems. The series offers various configurations tailored to different voltage and current requirements.

Replacement Considerations

Consult official Bourns substitution guides for compatible alternatives. Verify that any substitute maintains the dual bi-directional functionality, 850V rating, and 6-pin DFN footprint to ensure mechanical and electrical compatibility.
