HER105-T

Single Diodes Overview

The HER105-T is a silicon rectifier diode from Diodes Incorporated, designed for high-efficiency applications. It features a single element configuration housed in the DO-41 molded plastic case with plated axial leads. The device supports a maximum average forward rectified current of 1.0 A at an ambient temperature of 50°C and withstands a maximum recurrent peak reverse voltage of 400 V. Key electrical characteristics include a maximum instantaneous forward voltage of 1.75 V at 1.0 A DC and a maximum reverse recovery time of 100 ns. The junction capacitance is typically 20 pF. It operates within a temperature range of -65 to +150°C.

Single Diodes Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging details, as datasheets may list standard bulk variants. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the component matches the exact part number to avoid confusion with non-suffix versions or obsolete alternatives like the UF1005 series.

Single Diodes Selection Notes

Select this component for designs requiring reliable rectification with moderate reverse voltage ratings up to 400 V. Consider the thermal derating curve when determining operating currents at elevated ambient temperatures. Verify that the package dimensions fit the intended PCB layout and that the lead spacing aligns with manufacturing capabilities.

Single Diodes Part Context

This part belongs to the HER101 through HER106 series of high-efficiency rectifiers manufactured by Diodes Incorporated. These devices are characterized by their robust construction and suitability for general-purpose applications. The series utilizes glass passivated chip junctions to ensure stability and reliability under various operating conditions.

Single Diodes Replacement Considerations

The datasheet explicitly states that new designs should use the UF1001-UF1007 series instead of the HER101-HER106 series. The UF1005 is the direct functional equivalent within the recommended replacement lineup.
