A170D

Overview

The A170D is a standard recovery rectifier diode manufactured by Powerex Inc. It features a maximum repetitive peak reverse voltage of 1400 V and an average forward rectified current rating of 100 A. The device utilizes a DO-205AA (DO-8) axial leaded package designed for base or stud mounting. Key electrical characteristics include a maximum forward voltage drop of 1.3 V at 100 A and a maximum reverse leakage current of 20 mA at 1400 V. The junction temperature range extends from -40°C to 200°C, supporting high-temperature industrial applications.

Feature Summary

• High-voltage capability with a 1400 V DC reverse voltage rating
• Robust 100 A average forward current handling
• Standard recovery speed suitable for general-purpose rectification
• Axial leaded construction for secure mechanical mounting

Applications

• Industrial power supply rectification
• Motor drive circuits
• Welding equipment power stages
• General-purpose high-voltage rectifiers

Procurement Notes

Verify the specific suffix against the official datasheet to confirm exact electrical tolerances and packaging variations. Confirm RoHS compliance status as manufacturing revisions may alter environmental certifications. Ensure the ordering part number matches the required voltage and current ratings precisely. Cross-reference the manufacturer's latest documentation for any updates to the pinout or thermal specifications before finalizing procurement.

Selection Notes

Select this component when a 1400 V blocking voltage and 100 A continuous current are required in an axial package. The standard recovery characteristic makes it suitable for lower-frequency applications where fast switching is not critical. Evaluate the thermal management requirements based on the 1.3 V forward voltage drop at full load. Ensure the mounting method supports the mechanical stress associated with the DO-205AA form factor.

Part Context

This component belongs to the A170 series of standard recovery rectifiers produced by Powerex Inc. The series is designed for robust performance in demanding power electronics environments. The A170D specifically denotes the 1400 V variant within this lineup, sharing common package and thermal characteristics with other members of the family while differing in voltage ratings.
