BAS40-7

Single Diodes Overview

The BAS40-7-F is a surface-mount Schottky barrier diode manufactured by Diodes Incorporated in the SOT23 package. It features a peak repetitive reverse voltage of 40 V and a continuous forward current rating of 200 mA. The device exhibits a maximum forward voltage drop of 1.0 V at 40 mA and a maximum reverse leakage current of 200 nA at 30 V. Power dissipation is rated at 350 mW with a thermal resistance of 357 °C/W. Operating temperature ranges from -55°C to +125°C, and it includes PN junction guard ring protection.

Single Diodes Feature Summary

• Low forward voltage drop for efficient power conversion
• Fast switching capability with low reverse recovery time
• PN junction guard ring design for transient and ESD protection

Single Diodes Applications

• General purpose rectification in consumer electronics
• DC-DC converter output rectification
• Free-wheeling diodes in inductive load circuits

Single Diodes Procurement Notes

Verify the specific ordering suffix matches the required packing quantity, as the standard tape and reel contains 3000 units. Confirm RoHS compliance status and date code requirements against project specifications. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Check for any specific automotive qualification requirements if the application demands AEC-Q101 standards.

Single Diodes Selection Notes

Select this component for applications requiring compact surface-mount solutions with moderate current handling capabilities. The SOT23 package offers space efficiency for dense PCB layouts. Consider the 40V reverse voltage rating when designing circuits with potential voltage spikes. Evaluate the thermal performance based on the 350 mW dissipation limit and ambient operating conditions.

Single Diodes Part Context

This part belongs to the BAS40 series of Schottky barrier diodes from Diodes Incorporated. It shares electrical characteristics with variants like BAS40-04, BAS40-05, and BAS40-06, which differ primarily in internal configuration or pinout arrangements within the same SOT23 footprint. The series is designed for general-purpose high-speed switching applications.

Single Diodes Replacement Considerations

Direct replacements include BAS40-04-7-F, BAS40-05-7-F, and BAS40-06-7-F, provided pin compatibility is verified. Cross-brand equivalents should match the 40V reverse voltage, 200mA forward current, and SOT23 package constraints.
