1N3291RA

Single Diodes Overview

The 1N3291RA is a standard recovery silicon rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive reverse voltage of 400 V and an average forward rectified current of 100 A. The device exhibits a maximum forward voltage of 1.5 V at 100 A and a reverse leakage current of 24 mA at 400 V. It supports a surge current of 2300 A and operates within a junction temperature range of -55°C to +150°C. The component utilizes a DO-205AA (DO-8) stud mount package.

Single Diodes Feature Summary

• High current handling capability with 100 A average forward rectified current rating
• Robust surge withstand performance supporting up to 2300 A non-repetitive peak forward surge current
• Extended thermal operation range suitable for high-temperature environments up to 150°C junction temperature

Single Diodes Applications

• Industrial power supply rectification circuits
• Welding equipment power stages
• Motor drive inverter modules

Single Diodes Procurement Notes

Verify the specific suffix 'RA' against official Vishay documentation to confirm exact electrical tolerances and marking codes, as generic part numbers may vary. Confirm RoHS compliance status and packaging type directly with the manufacturer or authorized distributors prior to ordering. Ensure the stud mount configuration matches the mechanical design constraints of the target application board.

Single Diodes Selection Notes

Select this component when a single-phase standard recovery rectifier with 400 V blocking voltage and 100 A continuous current is required. The DO-205AA package necessitates a heatsink-compatible mounting solution. Evaluate thermal resistance requirements carefully due to the high forward current and associated power dissipation characteristics inherent to standard recovery silicon devices.

Single Diodes Part Context

The 1N3291RA belongs to the 1N329x series of high-power silicon rectifiers from Vishay. This series is designed for general-purpose rectification in industrial applications requiring robust current handling. The RA suffix typically denotes specific manufacturing lot or testing criteria defined by Vishay, distinct from other variants in the same voltage and current class.

Single Diodes Replacement Considerations

Cross-reference with other 1N329x series parts such as 1N3291R if electrical parameters match exactly. Verify pinout compatibility and thermal interface dimensions before substituting with equivalent products from other manufacturers offering similar DO-8 packages.
