Single Diodes Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and marking variations. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm that the received components match the TO-220AC physical dimensions and pinout configuration required by the design. Cross-reference the part number with the latest datasheet revision to avoid obsolete specifications.

Single Diodes Selection Notes

Select this component for circuits requiring moderate reverse voltage blocking with fast switching speeds. The 300 V rating suits low-to-medium voltage DC-DC conversion stages. Consider the 2 A current limit when designing thermal solutions. The TO-220AC package allows for direct heatsinking if higher thermal loads are anticipated during continuous operation.

Single Diodes Part Context

This device belongs to the SDURF series of fast recovery diodes from SMC Diode Solutions. The series offers various voltage ratings including 200 V, 300 V, and 400 V variants. These diodes are engineered for general-purpose high-frequency applications where rapid turn-off characteristics are critical for system efficiency and signal integrity.

Single Diodes Replacement Considerations

SDURF520 (200V variant) and SDURF540 (400V variant) share identical package and speed characteristics. Verify voltage headroom requirements before substituting. Ensure the replacement maintains the same 45 ns reverse recovery profile and TO-220AC footprint compatibility.
