1N1205R

Single Diodes Overview

The 1N1205R is a silicon power rectifier diode manufactured by Microchip Technology. It features a single-phase, single-element configuration with a maximum average forward current of 12 A and a peak repetitive reverse voltage of 500 V. The device utilizes a DO-4 (DO-203AA) glass-metal package with an anode case connection. It operates within a temperature range of -65°C to +200°C.

Single Diodes Feature Summary

• High thermal stability with an operating junction temperature up to 200°C
• Robust silicon construction for reliable power rectification
• Stud mount design for efficient heat dissipation

Single Diodes Applications

• Industrial power supplies
• Military electronic systems
• High-temperature rectifier circuits

Single Diodes Procurement Notes

Verify RoHS compliance status as sources indicate conflicting information regarding lead-free certification. Confirm the specific ordering suffix matches the required package variant and electrical specifications. Ensure the supplier provides valid manufacturer traceability documentation for this active component.

Single Diodes Selection Notes

Select this component when a 12A current rating and 500V reverse voltage are required in a stud-mount configuration. The wide operating temperature range makes it suitable for harsh environments where standard plastic packages may fail. Verify mechanical mounting constraints align with the DO-4 package dimensions.

Single Diodes Part Context

This part belongs to the 1N1205 series of silicon power rectifiers. It shares similar electrical characteristics with other variants in the family but differs in packaging and specific military or commercial qualification markings. The R suffix typically denotes a specific case style or testing level defined by the manufacturer.

Single Diodes Replacement Considerations

Direct substitutes include the 1N1205 and 1N1205E from Microchip. Cross-brand equivalents must match the 12A current, 500V voltage, and DO-4 package form factor. Verify thermal resistance and pinout compatibility before substitution.
