Procurement Notes

Verify the specific suffix 'R' against official Bourns documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the ordering quantity aligns with the manufacturer's standard reel size requirements. Cross-reference the datasheet revision date to guarantee compliance with current RoHS and REACH standards before finalizing procurement orders.

Selection Notes

Select this component when a small form factor is required alongside moderate current handling capabilities. The SOD-87 package offers a balance between thermal dissipation and board real estate efficiency. Consider the 50ns recovery time for applications requiring reduced switching losses, while ensuring the 400V rating exceeds the peak inverse voltage present in the target circuit topology.

Part Context

This part belongs to Bourns' series of surface-mount fast recovery rectifiers designed for miniaturization. The product line addresses the industry demand for smaller components that maintain robust electrical performance. These diodes are engineered to replace larger through-hole equivalents, facilitating denser circuit board designs without compromising reliability or thermal management in consumer and industrial electronics.

Replacement Considerations

Consult official substitution guides for equivalent fast recovery diodes in the SOD-87 package. Verify that any alternative maintains identical pinout configurations, voltage ratings, and thermal characteristics to ensure seamless integration into existing designs without requiring layout modifications.
