1N458/TR

Single Diodes Overview

The Microchip Technology 1N458/TR is a small signal switching diode designed for through-hole mounting in DO-204AH (DO-35) packages. It features a peak non-repetitive reverse voltage of 150 V and an average forward current rating of 150 mA. The device is supplied in tape and reel packaging, indicated by the /TR suffix, facilitating automated assembly processes.

Single Diodes Feature Summary

• Engineered as a high-conductance, low-leakage signal or computer diode suitable for general-purpose rectification and switching tasks.

Single Diodes Applications

• Signal processing circuits
• Computer logic interfaces
• General-purpose rectification

Single Diodes Procurement Notes

Verify that the /TR suffix confirms tape-and-reel packaging rather than bulk units. Confirm the manufacturer is Microchip Technology to ensure component authenticity and traceability. Check RoHS compliance status as specifications may vary by production batch.

Single Diodes Selection Notes

Select this component when a through-hole small signal diode with 150 V reverse voltage capability is required. Ensure the DO-204AH package fits the PCB layout constraints. Verify that the 150 mA forward current rating meets the circuit's load requirements.

Single Diodes Part Context

This part belongs to the 1N458 family of silicon junction diodes. While similar variants exist from other manufacturers like ON Semiconductor, the Microchip version specifies distinct electrical characteristics and packaging options tailored for specific industrial and commercial applications.

Single Diodes Replacement Considerations

Cross-reference with 1N458A for potential functional equivalence in low-signal applications. Verify pinout compatibility and thermal performance before substituting with generic equivalents.
