• Low leakage characteristics to minimize power loss
• Robust construction suitable for demanding thermal environments

Applications

• General purpose rectification circuits
• Signal switching applications
• Protection circuits requiring low leakage

Procurement Notes

Verify the manufacturer designation carefully, as this component is produced by onsemi under the Fairchild Semiconductor brand lineage. Confirm the specific suffix 'ATR' corresponds to the required reel or cut tape packaging format for your assembly line. Ensure compliance with RoHS and REACH standards by checking the latest product specification sheet for environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a standard axial leaded diode with high voltage capability is required. The DO-35 package offers reliable through-hole mounting for prototyping and industrial equipment. Consider the 150 V reverse voltage rating to ensure adequate margin against transient spikes in the target circuit design.

Part Context

This part belongs to the 1N458A series of rectifiers. It shares the same functional family as other general-purpose silicon junction diodes designed for switching and rectification tasks. The component is widely used in electronic assemblies where standard switching speeds and moderate current handling are sufficient.
