BAT46WFILM

Single Diodes Overview

The BAT46WFILM is a small signal Schottky barrier diode manufactured by STMicroelectronics. It features a MiniMELF (GLASS, MINIMELF-2) package with two terminals. The device has a maximum repetitive peak reverse voltage of 100V and an average rectified forward current of 150mA. The maximum non-repetitive peak forward surge current is 0.75A. The component utilizes silicon material and includes a guard ring construction for transient protection.

Single Diodes Feature Summary

• Schottky barrier technology providing low turn-on voltage and fast switching characteristics
• Guard ring construction designed to protect against excessive voltage transients such as electrostatic discharges
• MiniMELF glass encapsulation suitable for surface mount applications

Single Diodes Applications

• General purpose rectification in electronic circuits
• Clamping and protection applications requiring fast switching
• Low voltage power supply designs

Single Diodes Procurement Notes

Verify the specific manufacturer source when sourcing this component, as the BAT46W series is produced by multiple vendors including General Semiconductor and Diodes Incorporated. Confirm that the FILM suffix corresponds to the MELF package style required for your design. Ensure the selected part meets the 100V reverse voltage and 150mA current ratings specified for the BAT46W family.

Single Diodes Selection Notes

Select this component for applications requiring a compact surface mount Schottky diode with high breakdown voltage. The MiniMELF package offers space efficiency compared to larger through-hole options. Consider the 100V rating for higher voltage signal paths where standard low-voltage Schottky diodes might fail. Verify thermal management requirements for the 150mA continuous current limit in your specific circuit layout.

Single Diodes Part Context

This component belongs to the BAT46 series of small signal Schottky diodes. The series is characterized by its use in general-purpose applications where low forward voltage drop and rapid switching speeds are critical. The FILM designation typically indicates the MiniMELF axial-like surface mount package variant, distinguishing it from SOD-123 or DO-35 package versions within the same electrical specification family.

Single Diodes Replacement Considerations

Direct substitutes include BAT46WS and BAT46WH from other manufacturers, provided the package type matches the design constraints. Verify that replacement parts maintain the 100V reverse voltage and 150mA current ratings. Cross-reference datasheets to ensure compatibility with existing PCB footprints and thermal performance requirements.
