B330-13

Overview

The B330-13 is a Schottky barrier rectifier manufactured by Diodes Incorporated, designed for surface-mount applications. It features a single diode configuration within an SMA (DO-214AC) package. The device is rated for a maximum repetitive peak reverse voltage of 30V and an average forward rectified current of 3A. Key electrical characteristics include a maximum DC reverse leakage current of 50mA at 30V and a maximum non-repetitive peak forward surge current of 80A. The component operates reliably across a junction temperature range from -55°C to +150°C.

Feature Summary

• Utilizes Schottky barrier technology to achieve low forward voltage drop and minimal power loss.
• Incorporates guard ring die construction to provide enhanced protection against transient voltage events.
• Engineered with a molded plastic case material that meets UL flammability classification rating 94V-0.

Applications

• Low voltage, high frequency inverters
• Free wheeling circuits in power supplies
• Polarity protection for electronic systems

Procurement Notes

Verify the specific suffix designation when sourcing replacements, as variations such as B330-13-F may indicate RoHS compliance or halogen-free status. Confirm package integrity upon receipt, as the SMA surface-mount form factor requires careful handling during assembly. Ensure the supplier provides traceability documentation consistent with automotive reliability standards if the application demands AEC-Q101 qualification.

Selection Notes

Select this component for designs requiring efficient rectification in compact spaces where low forward voltage is critical for thermal management. The 3A current rating suits moderate power applications, while the 30V reverse voltage limit defines its suitability for lower voltage rails. Consider the operating temperature range when evaluating performance under extreme environmental conditions.

Part Context

This part belongs to the B3xx series of surface-mount Schottky barrier rectifiers from Diodes Incorporated. The series offers various voltage ratings and current capacities within standardized packages like SMA and SMB. These components are widely used in general-purpose power conversion and protection circuits due to their robust construction and efficiency.

Replacement Considerations

Compatible substitutes include the B330AE-13, which shares similar electrical specifications but utilizes an improved AE variant of the SMA package. Other equivalents within the same family, such as the B330B-13-F, offer comparable performance in different package footprints.
