Overview
The Microchip Technology 1N6079US is a surface-mount ultrafast recovery glass power rectifier rated for 50 V working peak reverse voltage and 12.0 A average rectified forward current at an ambient temperature of 70°C. It features a maximum forward voltage of 1.50 V at 37.7 A, a maximum reverse leakage current of 10.0 µA at the rated voltage, and a maximum reverse recovery time of 30 ns. The device supports a peak forward surge current of 175 A and operates within a junction temperature range of -65°C to +155°C.
Feature Summary
- Hermetically sealed voidless hard glass package with tungsten slugs
- Internal Category I metallurgical bonds for robust construction
- Triple-layer passivation coating
- Inherently radiation hard design
Applications
- Military and high-reliability applications
- Switching power supplies requiring extremely fast switching
- Applications demanding low forward loss
Procurement Notes
Verify the manufacturer origin as the product was originally produced by Microsemi, now part of Microchip Technology. Confirm that the specific ordering suffix matches the required screening level or package configuration. Ensure compatibility with the specified D-5C (Package G) footprint dimensions during PCB layout. Check for any relevant Product Change Notifications regarding assembly sites or material updates before finalizing procurement.
Selection Notes
Select this component when high reliability and radiation hardness are critical requirements. The 12 A current rating and 50 V reverse voltage define its operational limits. Consider the thermal resistance of 5.0°C/W for heat dissipation planning. Verify that the ultrafast 30 ns recovery time meets the switching frequency needs of the target circuit compared to standard or fast recovery alternatives.
Part Context
This device belongs to the 1N6073US through 1N6081US series of ultrafast recovery rectifiers. The series offers varying current ratings from 3 A to 12 A and reverse voltages from 50 V to 150 V. The 1N6079US specifically provides the highest current capacity in the lower voltage segment of this lineup.
