S3G-AQ

Single Diodes Overview

The Diotec S3G-AQ is a standard recovery surface-mount rectifier diode in the SMC (DO-214AB) package. It features a repetitive peak reverse voltage of 400 V and a maximum average forward rectified current of 3 A at 100°C. The device exhibits a low forward voltage of less than 1.0 V at 3 A and 25°C, with a typical reverse recovery time of approximately 1500 ns. It supports a peak forward surge current of 110 A at 60 Hz and operates within a junction temperature range of -50°C to +175°C.

Single Diodes Feature Summary

• AEC-Q101 qualified for automotive applications
• Low forward voltage drop for improved efficiency
• Standard recovery characteristics suitable for general-purpose rectification
• Compliant with RoHS, REACH, and Conflict Minerals regulations

Single Diodes Applications

• 50/60 Hz mains rectification
• General power supplies
• Polarity protection circuits

Single Diodes Procurement Notes

Verify that the specific part number includes the -AQ suffix to confirm AEC-Q101 qualification status. Ensure the ordering documentation explicitly references the S3G variant to guarantee the correct 400 V rating. Confirm compliance requirements such as RoHS and REACH are met for your specific supply chain needs before finalizing procurement.

Single Diodes Selection Notes

Select this component when a 400 V blocking capability is required in an SMC package. The -AQ suffix indicates automotive qualification, making it suitable for stricter reliability environments compared to the standard -Q or non-suffixed versions. Consider the 1500 ns reverse recovery time for switching frequency limitations in your design.

Single Diodes Part Context

This device belongs to the Diotec S3A through S3Y series of standard recovery SMD rectifiers. The series offers various voltage ratings from 50 V to 2000 V while maintaining a consistent 3 A current rating and SMC footprint. The S3G-AQ specifically targets the 400 V segment with enhanced automotive qualification standards.

Single Diodes Replacement Considerations

Direct substitutes must match the 400 V VRRM, 3 A IFAV, and SMC package dimensions. Verify reverse recovery time and forward voltage specifications against the original design requirements to ensure functional equivalence in the target application.
