B320AE-13-2477

Overview

The B320AE-13 is a Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single diode configuration in an SMA (DO-214AC) surface-mount package. The device supports a maximum average forward rectified current of 3 A and offers a repetitive peak reverse voltage rating of 20 V. Key electrical characteristics include a low forward voltage drop of 550 mV at the rated current, a high surge forward current capability of 80 A, and a maximum reverse leakage current of 200 uA. The component operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Utilizes silicon Schottky barrier technology for fast switching and low power loss
• Designed for surface-mount assembly using the standard SMA (DO-214AC) footprint
• Engineered for high thermal stability with an extended operating temperature range

Applications

• DC-to-DC converter freewheeling circuits
• Power supply output rectification
• Reverse polarity protection in electronic systems

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact binning or tape-and-reel specifications. Confirm RoHS compliance status through the latest datasheet revision. Ensure the ordering quantity aligns with factory packaging standards to avoid additional handling fees or cut-tape premiums during procurement.

Selection Notes

Select this component when a low forward voltage drop is required to minimize conduction losses in 20 V applications. The SMA package is suitable for automated SMD assembly processes. Compare the 3 A current rating against circuit load requirements to ensure adequate thermal headroom under continuous operation conditions.

Part Context

This part belongs to the B3xxAE series of Schottky rectifiers from Diodes Incorporated. The series provides various voltage ratings including 20 V, 30 V, 40 V, and 45 V options. All variants share similar physical dimensions and thermal characteristics, allowing for design flexibility while maintaining consistent board layout constraints across different voltage requirements.

Replacement Considerations

Compatible substitutes within the same family include B330AE-13, B340AE-13, and B345AE-13. These parts offer higher reverse voltage ratings but maintain identical current and package specifications. Verify that the increased voltage rating does not impact system efficiency requirements before substitution.
