Overview
The Powerex Inc. A170RB is a general-purpose standard recovery single diode designed for high-current applications. It features a maximum DC reverse voltage (Vr) of 200 V and an average rectified current (Io) of 100 A. The device utilizes a DO-205AA (DO-8) stud package with terminal installation, suitable for chassis mounting. Key electrical characteristics include a forward voltage (Vf) of 1.3 V at 100 A and a reverse leakage current of 20 mA at 200 V. The junction operating temperature range extends from -40°C to 200°C, ensuring reliability under thermal stress.
Feature Summary
- Standard recovery speed optimized for general-purpose rectification tasks
- Reverse polarity configuration for specific circuit protection needs
- Stud mount design facilitating robust mechanical attachment and heat dissipation
Applications
- Industrial power supply rectification
- Motor drive circuits
- Welding equipment power stages
Procurement Notes
Verify the exact suffix against manufacturer documentation to confirm pinout orientation and specific thermal resistance values. Ensure the mounting surface preparation meets the requirements for the stud interface to maintain optimal thermal performance. Confirm RoHS3 compliance status if required by your assembly specifications.
Selection Notes
Select this component when a 200 V blocking capability and 100 A continuous current rating are required in a stud-mount form factor. Consider the 1.3 V forward drop for conduction loss calculations. The wide junction temperature range supports operation in environments with significant thermal fluctuations without derating.
Part Context
This part belongs to the A170 series of general-purpose diodes manufactured by Powerex Inc. The series is characterized by robust construction for industrial environments. The A170RB specifically denotes the reverse polarity variant within this lineup, distinguishing it from standard orientation counterparts.
Replacement Considerations
Consult official cross-reference lists for direct substitutes. Verify that any alternative maintains the 200 V Vr, 100 A Io, and DO-205AA package dimensions. Ensure thermal management requirements are met by the replacement component.
