B220AF-13

Overview

The B220AF-13 is a 2.0A Schottky Barrier Rectifier manufactured by Diodes Incorporated in the SMAF surface-mount package. It features a peak repetitive reverse voltage of 20V and an average rectified output current of 2A. The device exhibits a maximum forward voltage drop of 0.5V at 2A and +25°C, with a non-repetitive peak forward surge current rating of 50A. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Guard ring die construction provides transient protection capabilities
• Optimized for low forward voltage drop to improve efficiency and reduce heat generation
• Engineered with reduced high-temperature reverse leakage to prevent thermal runaway
• Suitable for automated assembly processes

Applications

• Boost diode circuits
• Blocking diode configurations
• Recirculating diode applications

Procurement Notes

Verify the specific ordering suffix '-13' corresponds to the tape and reel packaging format containing 10,000 units per reel. Confirm that the SMAF case material meets UL flammability classification rating 94V-0 requirements for your design. Ensure compliance with RoHS directives and halogen-free specifications if mandated by project standards.

Selection Notes

Select this component when a 20V reverse voltage rating and 2A continuous current capacity are required in a compact SMAF footprint. Consider its low forward voltage characteristics for high-efficiency designs and evaluate its thermal resistance values against your system's heat dissipation constraints. Verify junction capacitance suitability for high-frequency operation needs.
