1N1205BR

Single Diodes Overview

The Microchip Technology 1N1205BR is a single standard recovery rectifier designed for stud mount applications. It features a maximum repetitive reverse voltage of 500 V and an average forward current rating of 12 A. The device exhibits a typical forward voltage drop of 1.2 V at 30 A and a maximum non-repetitive peak surge current capability of 250 A. Reverse leakage current is specified at 10 µA when tested at 500 V. The component operates within a junction temperature range of -65°C to +200°C and is housed in the DO-4 (DO-203AA) package.

Single Diodes Feature Summary

• High thermal stability with a maximum junction temperature rating of +200°C
• Robust surge handling capability for transient overload protection
• Standard recovery characteristics suitable for general-purpose rectification

Single Diodes Applications

• Industrial power supply rectification
• Battery charging circuits
• DC power distribution systems

Single Diodes Procurement Notes

Verify compliance requirements as this component does not meet RoHS standards. Confirm that the procurement channel accepts non-RoHS items. Ensure the ordering documentation explicitly references the 1N1205BR part number to distinguish it from other variants in the series. Check for specific packaging changes or manufacturing notices prior to finalizing orders.

Single Diodes Selection Notes

Select this component for applications requiring high-temperature operation up to +200°C. The 12 A current rating and 500 V blocking voltage define its electrical limits. Consider the stud mount configuration for mechanical attachment and thermal dissipation. Verify that the standard recovery speed meets the circuit timing requirements without necessitating faster switching devices.

Single Diodes Part Context

This rectifier belongs to the 1N1205 series, which shares identical physical dimensions and mounting styles but differs in voltage ratings. The BR suffix typically denotes specific testing or binning criteria defined by the manufacturer. It serves as a discrete solution for medium-power rectification tasks where through-hole or stud mounting is preferred over surface-mount technologies.

Single Diodes Replacement Considerations

Direct substitutes include the 1N1202BR, 1N1203BR, and 1N1204BR, provided the lower voltage ratings of those parts are acceptable for the application design.
