BAS70SV

Diode Arrays Overview

The BAS70SV is a dual Schottky barrier diode array manufactured by Fairchild Semiconductor. It features two independent Schottky diodes integrated into a single compact SOT-563F surface-mount package, designed for space-constrained electronic designs. The device offers a maximum repetitive peak reverse voltage of 70 V and an average forward rectified current of 70 mA per element. It utilizes a silicon planar structure with a glass passivated junction to ensure reliability. The component is RoHS compliant and lead-free, suitable for high-frequency switching applications where low forward voltage drop and fast switching speeds are required.

Diode Arrays Feature Summary

Diode Arrays Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor's semiconductor division has undergone corporate changes. Confirm that the part number corresponds to the original Fairchild specification rather than a successor or alternative vendor version. Check datasheet revisions to ensure compatibility with current design requirements, noting that some sources indicate this component may be discontinued or obsolete depending on the supplier.

Diode Arrays Selection Notes

Select the BAS70SV when a dual Schottky configuration is needed in a minimal footprint SOT-563 package. Ensure the application voltage does not exceed the 70 V rating and current demands stay within the 70 mA limit per diode. Consider thermal management requirements based on the package's power dissipation capabilities. Verify that the fast recovery characteristics align with the circuit's switching frequency needs.

Diode Arrays Part Context

The BAS70SV belongs to the BAS70 series of dual Schottky barrier diodes from Fairchild Semiconductor. This series is designed for general-purpose switching applications requiring low loss and high speed. The SOT-563F package provides a small outline transistor form factor, allowing for automated assembly and reduced PCB area compared to discrete components.

Diode Arrays Replacement Considerations

Public confirmed substitute part numbers were not identified in the provided documentation. Due to potential discontinuation status, verify availability with authorized distributors. Cross-reference with other dual Schottky diodes in SOT-563 packages from ON Semiconductor or other manufacturers if sourcing new production units.
