• Uninterruptible power supply (UPS) systems
• DC/DC converters
• Freewheeling diodes in low-voltage inverters
• Chopper motor drives

Single Diodes Procurement Notes

Verify the specific package type against design requirements, as this part number corresponds to the TO-262AA outline rather than the D2PAK variant. Confirm compliance with RoHS directives and lead-free termination specifications before integration. Ensure thermal management strategies account for the specified junction-to-case thermal resistance values during operation.

Single Diodes Selection Notes

Select this component when ultrafast recovery times are critical to reducing switching losses in high-frequency circuits. The TO-262AA package offers a compact surface-mount solution suitable for automated assembly processes. Evaluate the 400 V blocking capability and 8 A current handling against the specific load requirements of the target application to ensure adequate safety margins.

Single Diodes Part Context

This device belongs to the Vishay FRED Pt® family of ultrafast rectifiers, which are engineered for superior performance compared to standard fast recovery diodes. The series utilizes advanced semiconductor processing to balance forward voltage drop with rapid turn-off speeds. This specific model represents the TO-262AA packaging option within the broader VS-8ETU04 product line.

Single Diodes Replacement Considerations

VS-8ETU04S-M3 serves as a functional equivalent utilizing the D2PAK (TO-263AB) package instead of the TO-262AA form factor. Both devices share identical electrical characteristics and belong to the same FRED Pt® technology platform, allowing for potential mechanical substitution if board layout permits.

Single Diodes FAQ

What is the difference between VS-8ETU04-1-M3 and VS-8ETU04S-M3?

The primary difference lies in the physical package. VS-8ETU04-1-M3 uses the TO-262AA outline, while VS-8ETU04S-M3 utilizes the D2PAK (TO-263AB) outline. Electrical specifications remain identical.

What does the 'M3' suffix indicate for this component?

The M3 suffix denotes that the device is halogen-free, compliant with RoHS directives, and features lead-free terminations.
