B120B-13-F

Overview

The B120B-13-F is a surface-mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features an SMB (DO-214AA) package and provides a peak repetitive reverse voltage of 20 V with an average rectified output current of 1.0 A. The device exhibits a maximum forward voltage drop of 0.5 V at 1.0 A and a maximum leakage current of 0.5 mA at rated voltage. It supports a non-repetitive peak forward surge current of 30 A and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Guard ring die construction designed for transient protection
• Low power loss and high efficiency characteristics
• Surge overload rating capability up to 30 A peak
• Lead-free finish compliant with RoHS directives

Applications

• Polarity protection diodes
• Re-circulating diodes
• Switching diodes
• Free wheeling applications in low-voltage, high-frequency inverters

Procurement Notes

Verify the specific ordering suffix '-13-F' confirms the SMB package format and tape & reel packing quantity of 3,000 units. Confirm that the component meets the required environmental standards, specifically RoHS compliance and halogen-free status, as defined by the manufacturer's quality definitions. Ensure the application environment remains within the specified thermal and electrical limits outlined in the datasheet.

Selection Notes

Select this component when a 20 V reverse voltage rating and 1.0 A continuous current capacity are required in an SMB package. Consider the 0.5 V forward voltage drop for efficiency calculations in low-voltage circuits. Verify compatibility with automated assembly processes due to the surface-mount design. Evaluate thermal management requirements based on the junction-to-terminal thermal resistance provided in the specifications.

Part Context

This part belongs to the B120/B through B160/B series of 1.0A surface-mount Schottky barrier rectifiers. The 'B' suffix indicates the SMB package variant, distinguishing it from the SMA package version. The series offers various voltage ratings from 20 V to 60 V, allowing for flexible selection based on circuit blocking voltage requirements while maintaining consistent current handling and package dimensions.

Replacement Considerations

Direct substitutes within the same series include B130B-13-F (30 V), B140B-13-F (40 V), B150B-13-F (50 V), and B160B-13-F (60 V). These parts share identical physical packages and current ratings but differ in maximum repetitive reverse voltage. Ensure the replacement voltage rating exceeds the circuit's peak reverse voltage.
