S8K

Single Diodes Overview

The Diotec Semiconductor S8K is a standard recovery surface-mount rectifier diode designed for high-voltage applications. It features an 800 V repetitive peak reverse voltage and supports an average forward rectified current of 8 A at 100°C or 10 A at 75°C. The device utilizes the DO-214AB (SMC) package, ensuring robust mechanical stability. Key electrical characteristics include a maximum forward voltage of 1.1 V at 10 A and a typical reverse recovery time of 1500 ns. It withstands surge currents up to 360 A at 50 Hz and operates within a junction temperature range of -50°C to +150°C.

Single Diodes Feature Summary

• Low forward voltage drop for efficient power conversion
• High forward surge current rating for transient protection
• Compliant with RoHS directives

Single Diodes Applications

• 50/60 Hz mains rectification
• Power supplies
• Polarity protection

Single Diodes Procurement Notes

Verify the specific suffix requirements against your design needs. Standard versions are commercial grade. Automotive-grade variants require specific ordering suffixes such as -Q for compliance or -AQ for qualification under AEC-Q101 standards. Confirm that the selected part matches the required reliability level for your intended application environment before finalizing procurement.

Single Diodes Selection Notes

Select the S8K when an 800 V blocking capability is required in a compact SMC package. Ensure the thermal management strategy accounts for the specified thermal resistance values. Consider the -AQ suffix if automotive reliability standards are mandatory. Verify that the 1500 ns reverse recovery time aligns with the switching frequency requirements of the target circuit design.

Single Diodes Part Context

The S8K belongs to the S8A through S8M series of standard recovery SMD rectifiers from Diotec Semiconductor. This family offers various voltage ratings ranging from 50 V to 1000 V while maintaining consistent current handling capabilities. The series is engineered for general-purpose rectification tasks in both commercial and industrial electronics, providing a balance of performance and cost-effectiveness.

Single Diodes Replacement Considerations

Direct substitutes within the same voltage and current class should be evaluated based on package compatibility and reverse recovery specifications. Automotive replacements must meet AEC-Q101 qualifications if the original design requires it.
