B330AQ-13-F

Overview

The B330AQ-13-F is a single Schottky barrier rectifier manufactured by Diodes Incorporated, designed for surface-mount applications in the SMA (DO-214AC) package. It features a 30 V repetitive reverse voltage rating and supports a continuous forward current of 3 A. The device exhibits a maximum forward voltage drop of 500 mV at 3 A and a reverse leakage current of 500 µA at its rated voltage. It withstands a forward surge current of 100 A and operates within a junction temperature range of -55°C to +125°C or +150°C depending on specific datasheet revisions. The component holds AEC-Q101 qualification for automotive reliability.

Feature Summary

• Guard ring die construction provides enhanced transient protection capabilities
• Automotive-grade qualification ensures compliance with AEC-Q101 standards
• Optimized for low power loss and high efficiency in rectification circuits
• Designed for ideal suitability in automated assembly processes

Applications

• Automotive electronics requiring AEC-Q101 compliant components
• General-purpose rectification in DC power supply circuits
• Free-wheeling diode applications in inductive load switching
• Polarity protection circuits in consumer and industrial equipment

Procurement Notes

Verify the specific revision of the manufacturer's datasheet to confirm the maximum operating junction temperature, as sources indicate variations between +125°C and +150°C. Ensure the SMA (DO-214AC) package footprint matches the target PCB design. Confirm that the AEC-Q101 qualification status aligns with the specific automotive application requirements before finalizing procurement specifications.

Selection Notes

Select this component when a 3 A Schottky rectifier with a 30 V rating is required in an SMA package. The low forward voltage drop makes it suitable for improving efficiency in low-voltage DC systems. Consider the AEC-Q101 qualification if the application involves automotive environments. Compare thermal performance against alternatives if higher current or voltage ratings are needed for the specific circuit constraints.

Part Context

This part belongs to the B330 series of surface mount Schottky barrier rectifiers from Diodes Incorporated. The 'AQ' suffix typically denotes automotive-grade qualification and specific manufacturing controls. It is part of a broader family of SMA-packaged Schottky diodes offering various voltage ratings while maintaining consistent current handling and package dimensions for design flexibility.

Replacement Considerations

Direct replacements include other B330 variants from Diodes Incorporated with identical electrical characteristics but different packaging or qualification levels. Cross-brand equivalents must match the 3 A current, 30 V voltage, and SMA footprint. Verify that any substitute maintains the same forward voltage and reverse leakage specifications to ensure circuit compatibility.
