SB120-B

Single Diodes Overview

The SB120-B is a 1.0A Schottky Barrier Rectifier in the DO-41 plastic package, manufactured by Diodes Incorporated. It features a peak repetitive reverse voltage of 20V and an average rectified output current of 1.0A. The device utilizes guard ring die construction for transient protection and offers low forward voltage drop characteristics. Electrical parameters are specified at an ambient temperature of 25°C unless otherwise noted.

Single Diodes Feature Summary

• Guard ring die construction provides enhanced transient protection capabilities
• Low power loss and high efficiency design suitable for low voltage applications
• High surge capability with a non-repetitive peak forward surge rating of 40A
• Lead-free finish compliant with RoHS standards

Single Diodes Applications

• Low voltage, high frequency inverters
• Free wheeling diode circuits
• Polarity protection applications

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration. The SB120-B designation corresponds to bulk packaging containing 1,000 units per reel. Confirm that this packaging format aligns with assembly requirements before procurement. Ensure compatibility with standard through-hole mounting processes.

Single Diodes Selection Notes

Select this component for designs requiring a 20V blocking voltage and 1.0A continuous current handling. The DO-41 package supports through-hole mounting. Consider thermal derating curves when operating near maximum junction temperatures. Verify lead length specifications for PCB layout constraints.

Single Diodes Part Context

This part belongs to the SB120-SB160 series of Schottky barrier rectifiers from Diodes Incorporated. The series shares identical mechanical dimensions and general electrical characteristics, differing primarily in their peak repetitive reverse voltage ratings. The SB120 variant specifically addresses lower voltage circuit protection needs within this product family.

Single Diodes Replacement Considerations

Compatible substitutes include other 1A, 20V Schottky rectifiers in the DO-41 package. Verify equivalent forward voltage drop and reverse leakage current specifications. Ensure replacement devices meet the same transient protection and thermal resistance requirements.
