Procurement Notes

Verify the specific datasheet revision and environmental compliance status prior to procurement. Confirm that the selected packaging format matches the required manufacturing process. Ensure the operating conditions remain within the specified absolute maximum ratings to maintain device integrity. Cross-reference the ordering suffix to confirm the exact voltage rating and current specifications required for the circuit design.

Selection Notes

Select this component for circuits requiring fast switching speeds and low reverse recovery times. The 400 V rating makes it suitable for intermediate voltage rectification stages. Consider the thermal resistance values when designing heat dissipation strategies. Evaluate the forward voltage drop against system efficiency requirements. Ensure the PCB pad layout adheres to the recommended dimensions for optimal soldering and mechanical stability.

Part Context

This part belongs to the CD214A-FS1x series of fast response rectifiers from Bourns. The series offers various voltage ratings including 200 V, 600 V, and 800 V variants. All members share the same 1 A current rating and DO-214AC package footprint. The FS1G specifically denotes the 400 V version within this family of glass passivated silicon rectifiers.

Replacement Considerations

Compatible substitutes include other SMA packaged 400 V 1 A fast recovery rectifiers. Verify pinout compatibility and physical dimensions before substitution. Check if alternative components meet the specific 35 ns reverse recovery time requirement. Ensure the replacement maintains the same thermal resistance and operating temperature range.
