1N1197

Single Diodes Overview

The Microchip Technology 1N1197 is a standard recovery rectifier diode designed for high-power applications. It features a maximum repetitive peak reverse voltage of 500 V and an average forward rectified current rating of 40 A. The device utilizes a DO-203AB (DO-5) axial leaded package with stud mounting capabilities. Electrical characteristics include a maximum reverse leakage current of 10 µA at 500 V and a typical forward voltage drop of 1.19 V at 90 A. It operates within a junction temperature range of -65°C to +200°C.

Single Diodes Feature Summary

• High thermal stability with a maximum junction temperature of 200°C
• Robust mechanical construction suitable for stud mounting in the DO-203AB package
• Standard recovery speed optimized for general-purpose power conversion

Single Diodes Applications

• Industrial power supply rectification
• Battery charging circuits
• DC-to-AC inverter output stages

Single Diodes Procurement Notes

Verify compliance requirements prior to procurement, as this component is explicitly stated to be non-compliant with RoHS regulations. Confirm that the application environment accommodates the specific leaded package form factor and stud mounting hardware. Ensure that the 500V reverse voltage rating aligns with the system's peak inverse voltage demands to prevent breakdown under transient conditions.

Single Diodes Selection Notes

Select this component when high current handling and elevated temperature operation are required. The 40A continuous current rating supports heavy-duty loads, while the 500V blocking voltage provides adequate margin for medium-voltage systems. Consider the physical size and mounting constraints of the DO-203AB package during PCB or chassis layout design.

Single Diodes Part Context

The 1N1197 belongs to the 1N11xx series of high-power silicon rectifiers manufactured by Microchip Technology. This series is characterized by rugged construction and reliable performance in demanding industrial environments. The part serves as a discrete solution for power management tasks where integrated circuits cannot handle the required current levels.

Single Diodes Replacement Considerations

Consult official Microchip documentation for direct cross-reference equivalents. Verify that any substitute maintains the 40A current rating, 500V reverse voltage, and compatible DO-203AB package dimensions to ensure mechanical and electrical interchangeability.
