Overview
The B350AQ-13-F is a single Schottky barrier rectifier manufactured by Diodes Incorporated. It features a maximum average forward rectified current of 3 A and a repetitive peak reverse voltage of 50 V. The device utilizes silicon technology in an SMA (DO-214AC) surface-mount package. Key electrical parameters include a forward voltage of 700 mV at 3 A, a reverse leakage current of 500 uA, and a forward surge current capability of 80 A. It operates within a junction temperature range of -55 C to +125 C and holds AEC-Q101 qualification for automotive applications.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- Low forward voltage drop for improved efficiency
- Surface-mount SMA (DO-214AC) packaging
Applications
- Automotive power supply circuits
- DC-DC converter output rectification
- General-purpose low-voltage rectification
Procurement Notes
Verify the specific datasheet revision and AEC-Q101 certification status directly with Diodes Incorporated before finalizing design integration. Confirm that the SMA (DO-214AC) package dimensions match your PCB footprint requirements. Ensure thermal management strategies account for the specified operating temperature range and forward current ratings under actual load conditions.
Selection Notes
Select this component when a 3 A current rating and 50 V blocking voltage are required in a compact surface-mount form factor. The AEC-Q101 qualification makes it suitable for automotive environments where higher reliability than standard commercial grades is mandated. Compare against the B350A-13-F if automotive qualification is not strictly necessary, noting potential differences in testing protocols.
Part Context
This part belongs to the B3xxQ series of Schottky rectifiers from Diodes Incorporated, designed specifically for automotive electronics. The 'Q' suffix typically denotes AEC-Q101 qualification, distinguishing it from non-qualified variants like the B350A-13-F. These devices share similar electrical characteristics but differ in manufacturing quality control and testing standards required for automotive deployment.
Replacement Considerations
The B350A-13-F is a pin-compatible alternative within the same package but lacks explicit AEC-Q101 automotive qualification documentation in provided sources. Verify if the loss of automotive grade certification impacts system compliance before substitution.
