B120-13-F

Overview

The B120-13-F is a surface-mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features an SMA (DO-214AC) package and provides a peak repetitive reverse voltage of 20V with an average rectified output current of 1.0A. The device exhibits a maximum forward voltage drop of 0.5V at 1.0A and a leakage current of 0.5mA at rated voltage and 25°C. It supports a non-repetitive peak forward surge current of 30A 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 characteristics enabling high efficiency
• Surge overload rating capable of handling up to 30A peak current

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 matches the required SMA package configuration. Confirm compliance with RoHS directives and halogen-free requirements if mandated by project specifications. Ensure thermal management aligns with the junction-to-terminal thermal resistance limits during operation.

Selection Notes

Select this component when a 20V reverse voltage rating is sufficient for the circuit design. Consider the SMA package dimensions for PCB layout constraints. Evaluate the forward voltage drop against system efficiency targets under expected load currents.

Part Context

This part belongs to the B120/B through B160/B series of surface-mount Schottky barrier rectifiers. The series offers various reverse voltage ratings from 20V to 60V while maintaining a consistent 1.0A average rectified current capability across all variants.

Replacement Considerations

Compatible substitutes include other 20V Schottky rectifiers in the SMA package, such as the B120B-13-F variant which utilizes the SMB package but shares similar electrical characteristics.
