1N6077US

Overview

The Microchip Technology 1N6077US is a surface-mount ultrafast recovery glass power rectifier rated for 100 V working peak reverse voltage and 6.0 A average rectified forward current at 70°C case temperature. It features a maximum reverse recovery time of 30 ns, a maximum forward voltage of 1.76 V at 18.8 A, and a maximum reverse leakage current of 5.0 µA at 100 V. The device utilizes a voidless hermetically sealed glass package with tungsten slugs, operates within a junction temperature range of -65°C to +155°C, and supports a peak forward surge current of 75 A.

Feature Summary

• Voidless hermetically sealed glass construction with internal Category I metallurgical bonds
• Ultrafast recovery characteristics suitable for high-speed switching applications
• Inherently radiation hard design
• Triple-layer passivation for robust protection

Applications

• Military and other high-reliability applications
• Switching power supplies requiring extremely fast switching
• Applications demanding low forward loss

Procurement Notes

Verify the specific manufacturer origin, as the component history involves transitions between Microsemi and Microchip Technology. Confirm compliance requirements, noting that standard versions are not RoHS compliant. Ensure the ordering suffix matches the required package type and screening level, as prefixes indicate specific military or commercial variants. Check for recent Product Change Notifications regarding assembly sites or packaging labels before finalizing procurement.

Selection Notes

Select this component when a surface-mount ultrafast rectifier with high reliability and radiation hardness is required. The 1N6077US provides a balance of 6 A current handling and 100 V blocking capability in a hermetically sealed D-5B package. Consider thermal resistance and ambient operating temperatures, as the average current rating decreases significantly at lower case temperatures compared to the 70°C reference point.

Part Context

The 1N6077US belongs to the 1N6073US through 1N6081US series of ultrafast recovery rectifiers manufactured by Microchip Technology's Scottsdale Division. This series offers various current ratings from 3 A to 12 A and voltage ratings from 50 V to 150 V. The US suffix denotes the surface-mount Package E (D-5B) configuration, distinguishing it from axial-lead equivalents available in the same series.

Replacement Considerations

JAN1N6077 is a confirmed substitute part number offering equivalent electrical parameters in an axial-lead through-hole package.
