BAT48

Single Diodes Overview

The STMicroelectronics BAT48 is a general-purpose Schottky barrier rectifier diode housed in the DO-35 axial through-hole package. It features a peak repetitive reverse voltage of 40 V and an average forward rectified current of 350 mA. The device exhibits a maximum forward voltage of 900 mV at rated current and a low peak reverse leakage current of 25 µA. Designed for fast switching applications, it supports a non-repetitive peak forward surge current of 2 A. The component operates within a junction temperature range of -65°C to +125°C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific ordering suffix and package type when sourcing, as the standard BAT48 designation refers to the DO-35 through-hole variant. Confirm RoHS compliance status with the supplier, as manufacturing processes may vary by production batch. Ensure the selected component matches the required thermal and electrical specifications for the intended circuit design before finalizing procurement.

Single Diodes Selection Notes

Select this component for applications requiring low forward voltage drop and rapid switching speeds in a traditional through-hole form factor. Consider the BAT48JFILM as a surface-mount alternative if PCB space constraints necessitate an SOD-323 package while maintaining similar electrical parameters. Evaluate the maximum operating temperature limits to ensure reliability under varying environmental conditions.

Single Diodes Part Context

The BAT48 belongs to the BAT48 series of Schottky diodes manufactured by STMicroelectronics. These devices are designed for general-purpose use, offering a balance of speed and efficiency. The series includes variants with different packaging options to accommodate various assembly requirements, ranging from axial leads to surface-mount technologies.

Single Diodes Replacement Considerations

The BAT48JFILM is a manufacturer-recommended replacement available in an SMD package. Other potential substitutes include the 1N5825 or 1N6677-1, though these may differ in physical footprint or specific electrical tolerances. Verify compatibility with existing board layouts and thermal management strategies when considering alternatives.
