A190PE

Overview

The Powerex Inc. A190PE is a general-purpose standard recovery diode rated for 1500 V DC reverse voltage and 250 A average rectified current. It utilizes a DO-205 (R60) package with stud mount installation. The device exhibits a forward voltage of approximately 1.7 V at high currents and features a maximum reverse leakage current of 50 mA at its rated voltage. Designed for robust industrial environments, it operates within a junction temperature range of -40°C to +200°C.

Feature Summary

• High-voltage capability up to 1500 V for demanding power applications
• High-current handling with 250 A average rectified current rating
• Stud mount construction in a DO-205 package for secure mechanical attachment
• Extended thermal stability supporting junction temperatures up to 200°C

Applications

• Industrial motor drives and variable frequency drives
• High-power DC power supplies and rectifier bridges
• Welding equipment and heavy-duty industrial machinery

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct electrical characteristics and pinout compatibility. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Ensure mounting hardware specifications match the stud mount interface. Validate that the procurement channel provides authentic components from authorized distributors to prevent counterfeit risks.

Selection Notes

Select this component when system design requires high voltage blocking capability combined with substantial continuous current handling. The stud mount configuration is suitable for direct heatsink attachment in high-power density designs. Consider the forward voltage drop for thermal management calculations. Ensure the application environment supports the specified operating temperature range and mechanical vibration resistance associated with stud-mounted packages.

Part Context

This component belongs to Powerex Inc.'s lineup of high-power silicon rectifiers designed for industrial and traction applications. The A190PE represents a standard recovery variant within the broader family of high-current diodes. It shares mechanical form factors with other devices in the DO-205 series but differs in voltage and current ratings. These components are engineered for reliability in harsh electrical environments requiring robust semiconductor solutions.

Replacement Considerations

Cross-reference with equivalent models such as the A190N or R6202230XXOO only if voltage and current ratings align with specific circuit requirements. Verify that any substitute maintains compatible forward voltage characteristics and thermal performance. Ensure mechanical dimensions and stud thread specifications match existing mounting infrastructure before implementation.
