1N1127

Single Diodes Overview

The Microchip Technology 1N1127 is a single-element, one-phase silicon rectifier diode housed in the DO-203AA (DO4) glass-metal package. It features a maximum repetitive reverse voltage of 500V and an average forward current rating of 12A. The device exhibits a maximum non-repetitive peak forward surge current of 250A and a maximum forward voltage of 1.2V. Designed for robust power applications, it operates within a junction temperature range of -65°C to +200°C.

Single Diodes Feature Summary

• Utilizes a glass-metal sealed DO-203AA package for environmental protection
• Supports high junction temperatures up to 200°C
• Provides high surge current capability for transient protection

Single Diodes Applications

• Power supply rectification circuits
• Industrial equipment power stages
• High-temperature electronic assemblies

Single Diodes Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct manufacturer channels. Confirm that the specific order matches the 1N1127 designation rather than similar variants like 1N1128. Ensure compliance with RoHS exemption requirements as this component is not RoHS compliant. Validate packaging details against official datasheets prior to final procurement decisions.

Single Diodes Selection Notes

Select the 1N1127 when a standard recovery rectifier with a 500V reverse voltage rating and 12A continuous current capacity is required. Consider the DO-203AA package for stud mounting or chassis installation scenarios. Evaluate thermal management needs given the 200°C maximum operating temperature limit. Compare against alternative part numbers only if electrical parameters such as forward voltage or surge current differ from system specifications.

Single Diodes Part Context

The 1N1127 belongs to the standard rectifier diode family manufactured by Microchip Technology. It shares the DO-203AA (DO4) axial leaded package form factor common to legacy silicon rectifiers. This component serves as a discrete semiconductor solution for converting alternating current to direct current in power electronics systems requiring reliable performance under high thermal stress.
