1N1186R

Single Diodes Overview

The Microchip Technology 1N1186R is a high-reliability silicon standard recovery rectifier diode designed for demanding power applications. It features a stud-mount configuration within the DO-5 package, providing robust mechanical stability and efficient thermal dissipation. The device is qualified per MIL-PRF-19500/297 standards, ensuring performance in critical environments. Key electrical characteristics include a maximum repetitive peak reverse voltage of 200V and an average forward current rating of 35A to 40A, depending on specific manufacturing revisions. It incorporates a glass-passivated die with glass-to-metal seal construction, offering a surge current rating of up to 500 amps.

Single Diodes Procurement Notes

Verify the specific revision suffix and manufacturer lot code upon ordering, as historical production may involve multiple entities including Microsemi or GeneSiC under the same part number. Confirm that the received component matches the required MIL-PRF-19500/297 qualification level if specified for your application. Ensure proper handling procedures are followed due to the stud-mount package type and potential sensitivity to mechanical stress during installation.

Single Diodes Selection Notes

Select this component when a ruggedized, military-grade silicon rectifier is required for high-current applications. The stud-mount format necessitates compatible heatsinking infrastructure. Compare against other 1N118x series variants to ensure voltage and current ratings align with circuit demands. Consider the standard recovery speed for non-switching power applications rather than high-frequency switching scenarios.

Single Diodes Part Context

The 1N1186R belongs to the broader 1N118x family of silicon power rectifiers, which includes variants with different voltage ratings such as 1N1183 through 1N1186. These devices share common packaging and construction technologies but differ in their peak inverse voltage specifications. The 'R' suffix typically denotes a specific reel or tape-and-reel packaging option or a specific manufacturer revision within the Microchip portfolio.

Single Diodes Replacement Considerations

Direct substitutes include other 1N1186R units from authorized distributors or equivalent military-spec rectifiers meeting MIL-PRF-19500/297. Cross-reference with 1N1186A or similar variants only if voltage and current ratings are identical and package compatibility is confirmed.
