S1DFS

Single Diodes Overview

The S1DFS is a standard surface mount rectifier manufactured by Taiwan Semiconductor Corporation. It features an average forward current rating of 1A and supports maximum repetitive peak reverse voltages ranging from 200V to 1000V. The device utilizes a compact SOD-128 package designed for automated assembly processes. Key electrical characteristics include a maximum forward voltage drop of 1.1V at 1A, a reverse leakage current of 1µA at 1000V, and a junction capacitance of 9pF at 4V and 1MHz. The component operates within a junction temperature range of -55°C to 150°C.

Single Diodes Procurement Notes

Verify the specific voltage suffix (e.g., S1DFS-B) to confirm the exact reverse voltage rating required for your circuit design. Confirm RoHS compliance status and packaging details directly with the manufacturer or authorized distributors before placing orders. Ensure the selected variant matches the thermal management requirements of your final application.

Single Diodes Selection Notes

Select this component when a 1A current rating and high voltage blocking capability are needed in a small footprint. Compare the specific voltage grade against the peak inverse voltage present in the target circuit. Consider the SOD-128 package dimensions for PCB layout constraints and verify compatibility with standard pick-and-place equipment.

Single Diodes Part Context

This part belongs to the S1DF-T series of standard surface mount rectifiers produced by Taiwan Semiconductor. The series offers various voltage ratings to accommodate different power supply requirements while maintaining a consistent physical form factor. These components are widely used in low-power electronic devices requiring reliable DC conversion.

Single Diodes Replacement Considerations

Direct substitutes may include other 1A, 1000V standard rectifiers in the SOD-128 package from manufacturers such as Vishay or Diodes Inc. Verify pinout compatibility and ensure equivalent thermal and electrical specifications before substitution.
