1N1206

Single Diodes Overview

The Microchip Technology 1N1206 is a silicon standard recovery rectifier diode designed for high-power applications. It features a single-phase, single-element configuration housed in the DO-4 (DO-203AA) metal stud mount package. The device supports a maximum repetitive reverse voltage of 600V and an average forward rectified current of 12A. Key electrical characteristics include a maximum forward voltage of 1.2V at 30A and a maximum non-repetitive peak forward surge current of 250A. The component operates within a junction temperature range of -65°C to +200°C.

Single Diodes Feature Summary

• High thermal stability with a maximum junction temperature rating of +200°C
• Robust mechanical construction utilizing a metal stud mount design for efficient heat dissipation
• Capable of handling significant transient loads with a high peak surge current capacity

Single Diodes Applications

• Industrial power supply systems
• Welding equipment rectification circuits
• General-purpose power conversion modules

Single Diodes Procurement Notes

Verify the specific suffix designation when ordering, as variants such as 1N1206B or 1N1206AR exist with distinct packaging or manufacturer origins. Confirm RoHS compliance status, as certain versions are explicitly noted as non-compliant. Ensure the procurement channel provides official datasheets matching the exact part number to validate electrical parameters and physical dimensions before integration.

Single Diodes Selection Notes

Select this component for applications requiring high-voltage blocking capabilities combined with moderate continuous current ratings. The stud mount package necessitates specific heatsinking strategies compared to surface-mount alternatives. Evaluate the thermal resistance requirements against the expected ambient operating conditions to ensure the junction temperature remains within the specified +200°C limit during peak load operations.

Single Diodes Part Context

This component belongs to the legacy 1N series rectifiers, now manufactured under the Microchip Technology portfolio following industry consolidations. The DO-4 package represents a standardized form factor for high-power discrete semiconductors. While functionally similar to other 1N120x series parts, specific electrical tolerances and packaging materials may vary between original Microsemi designs and current Microchip production runs.

Single Diodes Replacement Considerations

Direct substitutes include the 1N1206B variant, which shares identical electrical specifications but may differ in packaging details. Verify pinout compatibility and thermal interface requirements when cross-referencing with generic 600V 12A stud-mount rectifiers from other manufacturers.
