SBR1A40S3Q-7

Single Diodes Overview

The SBR1A40S3Q-7 is a Super Barrier Rectifier diode from Diodes Incorporated, housed in an SOD-323 surface-mount package. It features a peak repetitive reverse voltage of 40V and an average rectified output current of 1A at 65°C. The maximum forward voltage drop is 0.55V at 1A, with a maximum reverse leakage current of 100µA at 40V. The device supports a junction temperature range of -65°C to +150°C and includes a non-repetitive peak forward surge current rating of 20A.

Single Diodes Procurement Notes

Verify the specific ordering suffix '-7' corresponds to the Tape & Reel carrier configuration containing 3,000 units per reel. Confirm that the component meets AEC-Q101 qualification standards and PPAP requirements if intended for automotive applications requiring specific change control protocols.

Single Diodes Selection Notes

Select this component when a compact SOD-323 footprint is required alongside a 1A continuous current rating. Ensure the application operates within the specified thermal limits, as the rated current decreases above 65°C ambient temperature. Verify compatibility with the 40V reverse voltage requirement and check if the specific switching speed aligns with circuit design needs.

Single Diodes Part Context

This part belongs to the SBR series of Super Barrier Rectifiers manufactured by Diodes Incorporated. It represents a specialized diode technology designed to offer performance advantages over traditional Schottky or standard silicon rectifiers, particularly regarding high-temperature operation and switching efficiency in small surface-mount packages.

Single Diodes Replacement Considerations

Direct replacements include the SBR1A40S3-7 (non-automotive grade) and the SBR140S1F-7 (SOD-123F package). Verify that substitute parts match the 40V reverse voltage, 1A current rating, and SMD mounting requirements before implementation.
