B260AF-13

Overview

The B260AF-13 is a Schottky barrier rectifier manufactured by Diodes Incorporated, designed for surface-mount applications in the SMAF (DO-217AC) package. It features a peak repetitive reverse voltage of 60 V and an average rectified output current of 2 A. The device exhibits a maximum forward voltage drop of 0.65 V at 2 A and 25°C, with a maximum reverse leakage current of 0.20 mA at 60 V and 125°C. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Provides low forward voltage drop for improved efficiency and cooler operation
• Features reduced high-temperature reverse leakage to increase reliability against thermal runaway
• Constructed with lead-free finish and complies with RoHS directives

Applications

• Boost diode circuits
• Blocking diode configurations
• Recirculating diode implementations

Procurement Notes

Verify component authenticity through authorized channels. Confirm datasheet revision DS39508 Rev. 2-2 matches specifications. Ensure SMAF packaging aligns with automated assembly requirements. Validate compliance with EU Directive 2002/95/EC and 2011/65/EU standards before integration.

Selection Notes

Select this component for general rectification where low forward voltage and high-temperature stability are critical. The SMAF package suits space-constrained designs requiring surface-mount technology. Consider the 60 V rating for low-voltage power supply applications needing efficient blocking capabilities.

Part Context

Part of the B250AF-B260AF series offering 2 A Schottky rectifiers. The B260AF variant specifically provides 60 V reverse voltage capability compared to the 50 V B250AF. Both share identical thermal characteristics and package dimensions for design flexibility within the same product family.

Replacement Considerations

B250AF-13 offers identical physical and electrical characteristics except for a lower 50 V reverse voltage rating. Verify circuit voltage margins accommodate the difference before substitution.
