SK38-AQ

Single Diodes Overview

The SK38-AQ is an SMD Schottky Barrier Rectifier Diode manufactured by Diotec Semiconductor, rated for a forward current of 3.0 A and a peak reverse voltage of 38 V. It features a maximum forward voltage of less than 0.85 V at 3 A and 25°C. The device exhibits a typical junction capacitance of 200 pF at 4 V and 1 MHz. Reverse leakage current is specified as less than 8.0 µA at 25°C and less than 5.0 mA at 125°C when VR equals VRRM. It operates within a junction temperature range of -50 to +150°C and is qualified under the AEC-Q101 automotive standard.

Single Diodes Feature Summary

• Automotive-grade qualification compliant with AEC-Q101 standards
• High thermal stability supporting operation up to 150°C junction temperature
• Low forward voltage drop for efficient power conversion
• Fast switching characteristics suitable for high-frequency applications

Single Diodes Applications

• General-purpose rectification in industrial electronics
• Power supply output rectification
• Polarity protection circuits
• Free-wheeling diodes in inductive load driving

Single Diodes Procurement Notes

Verify that the ordered component explicitly carries the -AQ suffix to ensure compliance with AEC-Q101 automotive reliability requirements. Confirm package integrity upon receipt, as surface-mount devices are sensitive to mechanical stress during handling. Cross-reference the manufacturer's latest datasheet revision to validate electrical parameters against specific design constraints before final integration.

Single Diodes Selection Notes

Select this component when a 3 A continuous current rating and 38 V blocking capability are required in a compact surface-mount form factor. Ensure the application environment supports the specified 150°C maximum junction temperature. Consider the 200 pF junction capacitance if operating at higher frequencies where capacitive loading may impact circuit performance or switching losses.

Single Diodes Part Context

This part belongs to the SK32 through SK315 series of SMD Schottky Barrier Rectifiers from Diotec Semiconductor. These devices utilize a DO-214AB (SMC) package to handle high surge currents up to 110 A. The -AQ designation specifically denotes automotive qualification, distinguishing it from standard commercial grade variants within the same electrical family.

Single Diodes Replacement Considerations

Consult official product change notices regarding the replacement of older SK8xx series parts with improved versions like the SK810-3G. Verify pinout compatibility and thermal resistance specifications when substituting with other manufacturers' 3 A SMC Schottky diodes.
