1N6078US

Overview

The Microchip Technology 1N6078US is a surface mount ultrafast recovery glass power rectifier with a working peak reverse voltage of 150 V. It features an average rectified forward current rating of 6.0 A at TEC=+70°C and 1.3 A at TA=55°C. The device exhibits a maximum reverse recovery time of 30 ns and a maximum surge current capability of 75 A. Electrical characteristics include a maximum forward voltage of 1.76 V at 18.8 A and a maximum reverse leakage current of 5.0 µA at the rated voltage.

Feature Summary

• Hermetically sealed voidless hard glass construction with tungsten slugs for high reliability
• Ultrafast recovery performance suitable for extremely fast switching applications
• Internal Category I metallurgical bonds ensuring robust mechanical integrity

Applications

• Military and other high-reliability applications
• Switching power supplies requiring low forward loss
• Applications demanding controlled avalanche and peak reverse power capability

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to long production cycles. Confirm specific screening levels or prefixes if military qualification (JAN, JANTX, etc.) is required, as standard suffixes do not indicate these options. Ensure compatibility with solder temperatures up to 260°C for 10 seconds during assembly processes.

Selection Notes

Select the 1N6078US when a 150 V reverse voltage rating and 6 A average current are necessary in a surface mount package. Consider its ultrafast 30 ns recovery time for high-frequency switching environments. Evaluate thermal resistance requirements, noting the 8.5°C/W junction-to-case value, to ensure adequate heat dissipation within the specified -65°C to +155°C junction temperature range.

Part Context

This component belongs to the 1N6073US through 1N6081US series of ultrafast recovery rectifiers manufactured by Microsemi's Scottsdale Division. The series offers varying current ratings from 3 A to 12 A across different package sizes while maintaining consistent ultrafast recovery characteristics. These devices are designed for high-reliability scenarios where failure is not an option.

Replacement Considerations

Axial-lead equivalents such as 1N6078 are available by omitting the US suffix. Military screened variants like JAN1N6078 or JANTXV1N6078 offer enhanced qualification under MIL-PRF-19500/503 standards.
