Procurement Notes

Verify the specific suffix TE61 against official ROHM documentation to confirm compliance with environmental standards and lead time requirements. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to validate current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when space constraints necessitate the GMD-2 package while maintaining a 30V blocking capability. Compare the 100mA current rating against circuit load requirements to ensure adequate headroom. Evaluate the thermal performance within the specified operating temperature range to guarantee long-term stability in the target application environment.

Part Context

This component belongs to the RB521 series of Schottky barrier diodes designed for low-voltage, high-speed switching applications. The series emphasizes miniaturization and efficiency, targeting modern consumer electronics where board real estate is limited. ROHM manufactures these devices using advanced silicon epitaxial processes to ensure consistent electrical performance across production batches.

Replacement Considerations

The RB521SM-30T2R serves as a pin-compatible alternative within the same family, offering identical electrical ratings but utilizing the SOD-523 package. Verify mechanical footprint compatibility during substitution. Other variants like the RB521S-30 share similar specifications but may differ in packaging or automotive qualification status.
