• High-speed response to transient events

Applications

• Video transcoder circuit protection
• Input line surge mitigation
• ESD and lightning strike protection

Procurement Notes

Verify the specific suffix 'WH' against the manufacturer's official datasheet to confirm terminal finish and packaging configuration. Ensure the selected component matches the required 500V rating and 200mA current handling for the target application environment.

Selection Notes

Select this component for applications requiring bidirectional surge protection in compact footprints. Consider the -55°C to +125°C operating range and DFN package constraints when designing PCB layouts for video or industrial signal lines.

Part Context

This part belongs to the TBU-CA series of high-speed protectors from Bourns. These devices are designed to prevent catastrophic damage from transient surges while maintaining safe input levels for downstream circuitry.

Replacement Considerations

Consult official substitution lists for equivalent bidirectional TBU devices with matching voltage and current ratings.
