1N3295A

Single Diodes Overview

The Powerex Inc. 1N3295A is a silicon power rectifier diode designed for high-current applications. It features a maximum repetitive peak reverse voltage (Vrrm) of 1000 V and an average forward current (Io) of 100 A. The device utilizes a DO-205AA (DO-8) chassis mount package with stud mounting capabilities. Key electrical characteristics include a non-repetitive peak forward surge current of 2300 A and an operating junction temperature range from -55°C to +150°C.

Single Diodes Feature Summary

• High-power rectification capability with 100 A average forward current rating
• Robust 1000 V reverse voltage blocking capacity for industrial environments
• Chassis mount construction in DO-8 package for efficient thermal management
• Wide operating junction temperature range supporting extreme conditions

Single Diodes Applications

• Industrial motor drives and variable frequency drives
• Welding equipment power supplies
• DC power supply rectification circuits
• Inverter and converter systems

Single Diodes Procurement Notes

Verify manufacturer documentation for obsolescence status, as some sources indicate discontinuation. Confirm exact datasheet revisions and testing standards before integration. Ensure mounting hardware compatibility with the DO-8 stud configuration. Validate thermal interface material requirements for the specified junction temperature range. Check for alternative sourcing if original production has ceased.

Single Diodes Selection Notes

Select this component when high current handling and robust mechanical mounting are required. The DO-8 package facilitates direct heatsink attachment for effective heat dissipation. Consider the 1000 V rating for medium-voltage AC-to-DC conversion tasks. Evaluate thermal resistance parameters against system cooling capabilities. Ensure surge current ratings exceed expected transient loads in the application circuit.

Single Diodes Part Context

The 1N3295A belongs to the standard silicon power rectifier family, historically manufactured by entities such as Microsemi and GeneSiC. Powerex Inc. produces variants within this designation. These devices serve as fundamental building blocks in heavy-duty power electronics, replacing older glass-encapsulated types with more durable metal-case constructions suitable for high-stress industrial operations.

Single Diodes Replacement Considerations

Cross-reference with 1N3295 equivalents from other manufacturers. Verify pinout and mounting hole dimensions match existing PCB or chassis layouts. Compare thermal resistance values to ensure equivalent cooling performance. Confirm voltage and current derating curves align with specific application requirements.
