1N457ATR

Single Diodes Overview

The onsemi 1N457ATR is a small signal switching diode designed for general-purpose applications. It features a single configuration housed in a DO-35 through-hole package. The device supports a peak reverse voltage of 70 V and an average forward current of 200 mA, with a maximum surge current rating of 4 A. Electrical characteristics include a forward voltage of 1 V and a reverse current of 25 nA. It operates within a temperature range from -65 C to +175 C.

Single Diodes Feature Summary

• High conductance performance for efficient signal handling
• Low leakage current characteristics for improved isolation
• Robust thermal stability across extended operating temperatures

Single Diodes Applications

• General purpose rectification circuits
• Small signal switching applications
• Protection against transient voltages

Single Diodes Procurement Notes

Verify the specific suffix 'ATR' confirms the reel or cut tape packaging format required for automated assembly processes. Confirm RoHS and REACH compliance status directly with the manufacturer documentation before integration. Ensure the ordering quantity aligns with the factory pack size specifications provided in the official datasheet to avoid partial reel issues.

Single Diodes Selection Notes

Select this component when a standard axial leaded diode is required for high-speed switching tasks. The DO-35 package offers a compact footprint suitable for through-hole PCB layouts. Consider the 70 V reverse voltage rating to ensure adequate margin for the intended circuit's peak inverse voltage conditions during operation.

Single Diodes Part Context

This part belongs to the 1N457 series of small signal switching diodes manufactured by onsemi. The series is characterized by its glass passivated junction construction, which provides reliable performance in various electronic environments. The 'ATR' designation specifically indicates the bulk packaging method used for distribution and inventory management.

Single Diodes Replacement Considerations

Direct substitutes include other 1N457A variants from different manufacturers that meet the same JEDEC registration standards. Verify pinout compatibility and electrical ratings such as peak reverse voltage and forward current before implementing any cross-brand replacement.
