1N1348R

Single Diodes Overview

The Microchip Technology 1N1348R is a standard recovery single diode designed for general-purpose rectification applications. It features a maximum repetitive reverse voltage of 600 V and an average forward rectified current of 16 A. The device utilizes a stud mount configuration within the DO-4 (DO-203AA) package, facilitating robust thermal management and mechanical stability in high-power circuits. Key electrical characteristics include a forward voltage of 1.3 V at 30 A and a maximum reverse leakage current of 10 µA at 600 V. The component supports a junction temperature range from -65°C to 200°C and exhibits a standard recovery time exceeding 500 ns.

Single Diodes Feature Summary

• High thermal capacity via stud mount installation for efficient heat dissipation
• Standard recovery speed suitable for general-purpose power conversion
• Wide operating junction temperature range for harsh environments

Single Diodes Applications

• Industrial power supply rectification
• Motor drive circuit protection
• General-purpose DC power conversion

Single Diodes Procurement Notes

Verify that the specific order matches the 1N1348R designation, as generic listings may refer to similar but distinct variants. Confirm RoHS compliance status, as this series may not meet current environmental directives depending on the manufacturing date code. Ensure the supplier provides official datasheets and traceability documentation to validate authenticity and technical specifications before integration into designs.

Single Diodes Selection Notes

Select this component when a rugged, stud-mount diode with 600 V blocking capability and 16 A continuous current rating is required. The DO-4 package is ideal for applications needing direct mounting to heatsinks or chassis for superior thermal performance compared to leaded packages. Consider the standard recovery characteristic for non-switching or low-frequency applications where fast recovery is not critical.

Single Diodes Part Context

The 1N1348R belongs to Microchip's legacy standard rectifier lineup, often associated with the S/R20 series documentation. These components are widely used in industrial equipment due to their proven reliability and standardized pinout. The 'R' suffix typically denotes a specific tape-and-reel or bulk packaging variant, though the electrical characteristics remain identical to the base 1N1348 part number.

Single Diodes Replacement Considerations

Direct substitutes include the 1N1348 base part number. Verify that any replacement maintains the same DO-4 stud mount footprint and thermal resistance characteristics to ensure compatibility with existing heatsinking infrastructure.
