B220AQ-13-F

Overview

The B220AQ-13-F is a silicon Schottky barrier rectifier manufactured by Diodes Incorporated, designed for surface-mount applications in the SMB (DO-214AA) package. It features a single diode configuration with a maximum repetitive peak reverse voltage of 20 V and an average forward rectified current rating of 2 A. The device exhibits a low forward voltage drop of 500 mV at rated current and supports a high non-repetitive peak forward surge current of 50 A. It operates within a junction temperature range of -65°C to +150°C and holds AEC-Q101 automotive qualification.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• Low forward voltage drop for improved efficiency
• Guard ring structure for enhanced stability

Applications

• Automotive power supply circuits
• DC-DC converter output rectification
• Free-wheeling diode applications in inductive loads

Procurement Notes

Verify the specific suffix 'Q' against official Diodes Incorporated documentation to confirm AEC-Q101 automotive qualification status, as standard variants may lack this certification. Ensure the SMB package footprint matches the target PCB layout. Cross-reference the datasheet revision date to confirm parameter consistency before finalizing component selection for production.

Selection Notes

Select this component when a 20 V reverse voltage rating and 2 A continuous current capacity are required in a compact SMB package. The AEC-Q101 qualification makes it suitable for automotive environments where thermal stability up to 150°C is necessary. Compare the 500 mV forward voltage against alternative rectifiers to ensure optimal power loss management in the specific circuit design.

Part Context

This part belongs to the B220AQ/Q series of Schottky rectifiers from Diodes Incorporated. The series offers various voltage ratings within the same physical footprint, allowing for design flexibility. The 'Q' designation typically indicates automotive-grade processing and testing, distinguishing it from standard industrial grade counterparts in the same package family.

Replacement Considerations

Direct substitutes include other 20 V, 2 A Schottky diodes in the SMB package with equivalent or superior electrical characteristics. Verify that any replacement maintains the AEC-Q101 requirement if used in automotive applications. Check for pinout compatibility and thermal resistance similarities to ensure seamless integration without PCB redesign.
