1N5397-E3/54

Overview

The 1N5397-E3/54 is a general-purpose plastic rectifier manufactured by Vishay General Semiconductor. It features a maximum average forward rectified current of 1.5 A and a maximum repetitive peak reverse voltage of 600 V. The device utilizes a DO-41 (DO-204AL) package with matte tin-plated leads. Key electrical characteristics include a maximum instantaneous forward voltage of 1.4 V at 1.5 A, a maximum DC reverse current of 5.0 μA at rated blocking voltage, and a typical reverse recovery time of 2.0 μs. It supports a peak forward surge current of 50 A and operates within a junction temperature range of -50 °C to +150 °C.

Feature Summary

• Low forward voltage drop for efficient power conversion
• Low leakage current under rated conditions
• High forward surge capability for transient protection
• Matte tin plated leads ensuring solderability per J-STD-002

Applications

• General purpose rectification in power supplies
• Inverter circuits
• Converter applications
• Freewheeling diode implementation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and base quantity. Confirm RoHS compliance status and material categorization requirements prior to procurement. Ensure lead length specifications align with assembly processes, as thermal resistance ratings depend on specific mounting lengths. Validate that the component meets regional regulatory standards applicable to the intended deployment environment.

Selection Notes

Select this component for standard rectification tasks requiring a 600 V blocking voltage and 1.5 A continuous current capacity. Consider the DO-41 through-hole package for manual or standard automated assembly lines. Evaluate the thermal resistance characteristics relative to the available heatsinking or PCB copper area. Ensure the operating junction temperature range accommodates the highest expected ambient temperatures in the target application design.

Part Context

This part belongs to the 1N539x series of general-purpose plastic rectifiers from Vishay. The series covers various voltage ratings from 50 V to 1000 V while maintaining consistent current handling and package dimensions. The E3 suffix indicates RoHS compliance and adherence to specific material categorization guidelines defined by the manufacturer. The /54 suffix denotes delivery in a 13-inch diameter paper tape and reel format.

Replacement Considerations

Direct substitutes within the same Vishay series include parts with identical current ratings but different voltage capabilities, such as 1N5396 or 1N5398. Cross-manufacturer replacements must match the DO-41 footprint, 1.5 A current rating, and 600 V minimum reverse voltage specification.
