BAS40

Single Diodes Overview

The BAS40 is a silicon Schottky barrier rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a single diode element housed in an SOT-23 surface-mount package with three terminals. The device is rated for a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 0.2 A at 25°C. Key electrical characteristics include a low forward voltage drop and minimal reverse leakage current, ensuring efficient performance in high-speed switching applications.

Single Diodes Feature Summary

• Utilizes Schottky barrier technology to achieve fast switching speeds and low power loss.
• Features a compact SOT-23 surface-mount package designed for automated assembly processes.
• Constructed using silicon material to provide robust reliability under specified operating conditions.

Single Diodes Applications

• High-frequency rectification in consumer electronics
• Power supply input rectification circuits
• DC-DC converter output rectification

Single Diodes Procurement Notes

Verify the specific manufacturer datasheet for the BAS40 produced by Taiwan Semiconductor Corporation to confirm exact electrical tolerances and thermal ratings. Ensure the component matches the required SOT-23 package dimensions and terminal configuration for your PCB layout. Cross-reference ordering codes with official distributor catalogs to avoid confusion with similar part numbers from other manufacturers.

Single Diodes Selection Notes

Select this component when a small signal Schottky diode with a 40V reverse voltage rating and 0.2A current capacity is required. The SOT-23 package is suitable for space-constrained designs requiring surface-mount technology. Consider the forward voltage drop and reverse recovery time specifications relative to your circuit's efficiency and speed requirements compared to standard PN junction diodes.

Single Diodes Part Context

This component belongs to the family of small-signal Schottky rectifiers commonly used in low-voltage, high-efficiency power management applications. The BAS40 designation typically refers to a generic specification shared across multiple semiconductor fabricators, though electrical parameters may vary slightly between brands such as Taiwan Semiconductor, Diodes Inc., or Nexperia. It serves as a fundamental discrete semiconductor device for signal processing and power conversion.

Single Diodes Replacement Considerations

Direct replacements include BAS40 variants from other manufacturers like Diodes Incorporated (BAS40-06-7) or Nexperia (BAS40W). Verify that substitute parts maintain the same SOT-23 footprint, 40V reverse voltage rating, and 0.2A current handling capability to ensure mechanical and electrical compatibility without redesigning the circuit board.
