A170N

Single Diodes Overview

The Powerex A170N is a silicon rectifier diode rated for 800 V maximum repetitive reverse voltage and 100 A average forward current. It utilizes the DO-205AA (DO-8) package with stud mount installation. The device features a standard recovery time exceeding 500 ns and a maximum forward voltage of 1.3 V at 100 A. Operating junction temperature ranges from -40°C to +200°C, with a leakage current of 20 mA at 800 V.

Single Diodes Feature Summary

• High thermal stability with extended operating junction temperature up to 200°C
• Robust mechanical design utilizing stud mount configuration for efficient heat dissipation
• Standard recovery characteristics suitable for general-purpose power conversion applications

Single Diodes Applications

• Industrial motor drives and variable frequency drives
• Welding equipment power supplies
• General purpose rectification in high-current DC circuits

Single Diodes Procurement Notes

Verify the specific voltage rating against project requirements, as the A170 series includes variants with different breakdown voltages such as 1400V or 1600V. Confirm that the DO-205AA stud mount interface matches the heatsink or chassis mounting hardware specifications. Ensure compliance with RoHS3 directives if required by the end-use environment. Cross-reference datasheet electrical limits with actual circuit conditions to prevent overstress.

Single Diodes Selection Notes

Select this component when an 800V blocking capability and 100A continuous current handling are required within a stud-mount form factor. Consider the standard recovery speed for non-switching or low-frequency applications where fast recovery is not critical. Evaluate thermal management solutions compatible with the DO-8 package to maintain junction temperatures within the specified 200°C limit under full load conditions.

Single Diodes Part Context

The A170N belongs to the A170 series of high-power silicon rectifiers manufactured by Powerex Inc. This series is designed for demanding industrial environments requiring reliable high-current rectification. The DO-205AA package provides a standardized footprint for mounting on cold plates or chassis structures, facilitating integration into larger power electronic systems.

Single Diodes Replacement Considerations

Direct substitutes must match the 800V/100A rating and DO-205AA package. Verify pinout compatibility and thermal resistance values before substitution.
