• Suitable for general-purpose rectification and switching tasks
• Robust thermal stability across extended operating temperatures

Single Diodes Applications

• General purpose rectification circuits
• Signal switching applications
• Protection against reverse polarity

Single Diodes Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with onsemi before integration. Confirm that the DO-35 axial leaded package aligns with your PCB footprint requirements. Ensure the 150 V reverse voltage rating meets the circuit's peak inverse voltage demands. Check for any recent process change notifications regarding manufacturing locations or material composition updates.

Single Diodes Selection Notes

Select this component when a standard silicon switching diode with moderate voltage blocking capability is required. The 500 mA forward current rating supports basic power handling needs. Consider the DO-35 package size for space-constrained through-hole designs. Evaluate the 25 uA reverse leakage against strict low-power standby requirements.

Single Diodes Part Context

This part belongs to the 1N458A series of small signal switching diodes manufactured by onsemi. It shares the base die and electrical characteristics with other variants in the family, distinguished primarily by packaging and suffix designations. The 1N458A designation indicates a specific reverse voltage rating within the broader series lineup.

Single Diodes Replacement Considerations

Direct substitutes include parts sharing the 1N458A JEDEC registration number. Verify pinout compatibility and package dimensions for equivalent DO-35 devices. Cross-reference specifications for forward voltage and reverse leakage to ensure functional parity.
