BAS40-7-F-31

Single Diodes Overview

The BAS40-7-F-31 is a Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single diode configuration housed in an SOT-23 surface-mount package. The device is rated for a repetitive reverse voltage of 40 V and supports a continuous forward current of 200 mA. Key electrical characteristics include a maximum forward voltage of 1 V at specified currents, a peak non-repetitive forward surge current of 600 mA, and a low reverse leakage current of 200 nA. The component operates within a junction temperature range of -55°C to +150°C and dissipates up to 350 mW of power.

Single Diodes Feature Summary

• Utilizes silicon Schottky technology to achieve fast switching speeds with minimal reverse recovery time.
• Provides high efficiency through low forward voltage drop characteristics suitable for power-constrained designs.
• Features a compact SOT-23 surface-mount footprint designed for automated assembly and space-saving applications.

Single Diodes Applications

• DC-DC converter output rectification
• Power supply freewheeling diodes
• Reverse polarity protection circuits

Single Diodes Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm exact packaging and tape-and-reel specifications. Ensure the ordering part number matches the required AEC-Q101 qualification status if automotive compliance is mandatory. Cross-reference datasheet revisions to confirm pinout consistency and thermal parameters before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a low-cost, small-footprint Schottky diode is required for general-purpose rectification. Compare the 40 V rating against circuit peak inverse voltages to ensure adequate margin. Evaluate the 200 mA current limit against load requirements and consider thermal derating at elevated ambient temperatures to maintain reliability.

Single Diodes Part Context

This part belongs to the BAS40 series of small-signal Schottky diodes from Diodes Incorporated. The series includes various configurations such as dual diodes and different package options like SOT-323 and SOT-363. The BAS40-7-F-31 specifically denotes the single-diode variant in the standard SOT-23 package, widely used in consumer electronics and industrial control systems.

Single Diodes Replacement Considerations

Direct substitutes include other BAS40 variants from Diodes Incorporated or equivalent parts from manufacturers like Nexperia and ON Semiconductor. Verify that replacement components match the 40 V reverse voltage, 200 mA forward current, and SOT-23 package dimensions. Check for identical thermal resistance and reverse leakage specifications to ensure circuit performance parity.
