BAS40W-QX

Single Diodes Overview

The BAS40W-QX is a dual common-anode switching diode manufactured by Nexperia USA Inc. It utilizes Trench Schottky technology to achieve low forward voltage and fast switching characteristics. The device is housed in an SOD882 surface-mounted plastic package, designed for high-density PCB layouts. It operates within a temperature range of -55 °C to +150 °C and is qualified to AEC-Q101 standards for automotive applications.

Single Diodes Feature Summary

• Dual common-anode configuration integrates two independent Schottky barriers into a single compact component.
• Trench Schottky technology provides low forward voltage drop and minimal reverse leakage current.
• Fast switching performance reduces power loss and electromagnetic interference in high-frequency circuits.

Single Diodes Applications

• Automotive infotainment system signal routing
• DC-DC converter freewheeling and protection
• OR-ing logic for redundant power supply inputs

Single Diodes Procurement Notes

Verify the specific suffix 'QX' against the official Nexperia datasheet to confirm AEC-Q101 qualification status and exact marking codes. Ensure the ordering part number matches the required tape-and-reel packaging specifications for automated assembly processes.

Single Diodes Selection Notes

Select this component when space constraints require a dual-diode solution in an ultra-small footprint. It is suitable for designs needing low capacitance and fast recovery times. Verify that the maximum reverse voltage and continuous forward current ratings exceed the circuit's peak operating conditions.

Single Diodes Part Context

This device belongs to Nexperia's BASxx series of small-signal Schottky diodes. The series is engineered for general-purpose switching and RF detection applications. The QX variant specifically denotes automotive-grade reliability and compliance with stringent quality standards required for vehicle electronics manufacturing.

Single Diodes Replacement Considerations

Direct substitutes include other dual common-anode Schottky diodes in the SOD882 package, such as the BAS40W or BAS40WS from compatible manufacturers. Confirm pinout compatibility and thermal resistance values before substitution.
