1N4003/54

Single Diodes Overview

The Vishay 1N4003/54 is a general-purpose plastic rectifier diode in the 1N4001-1N4007 series. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current rating of 1.0 A at 75 °C ambient temperature. The device utilizes a DO-204AL (DO-41) molded epoxy package with matte tin-plated leads. Key electrical characteristics include a maximum instantaneous forward voltage of 1.1 V at 1.0 A, a maximum DC reverse current of 5.0 μA at rated blocking voltage, and a typical junction capacitance of 15 pF. It supports a peak forward surge current of 30 A for 8.3 ms sine-wave pulses.

Single Diodes Procurement Notes

Verify that the ordering suffix matches the required delivery mode, as code 54 indicates tape and reel packaging while other codes may denote ammo packs. Confirm RoHS compliance status, noting that the E3 suffix denotes compliance. Ensure the component meets specific thermal resistance requirements based on lead length and mounting conditions. Validate suitability against application-specific constraints, as these devices are not qualified for automotive standards.

Single Diodes Selection Notes

Select this component when a standard recovery rectifier with a 200 V reverse voltage rating is required for through-hole mounting. Consider the 1.0 A continuous current capacity and 30 A surge capability for load conditions. Evaluate the thermal performance relative to the 50 °C/W junction-to-ambient resistance. Verify that the operating temperature range of -50 °C to +150 °C aligns with the environmental demands of the target circuit design.

Single Diodes Part Context

This part belongs to the Vishay 1N4001 through 1N4007 family of general-purpose plastic rectifiers. These components share identical mechanical dimensions and current ratings, differing primarily in their maximum repetitive peak reverse voltage ratings which range from 50 V to 1000 V across the series. The 1N4003 variant specifically addresses applications requiring a 200 V blocking capability within this standardized product line.

Single Diodes Replacement Considerations

Direct substitutes within the same Vishay series include 1N4001-E3/54, 1N4002-E3/54, 1N4004-E3/54, 1N4005-E3/54, 1N4006-E3/54, and 1N4007-E3/54. Cross-manufacturer replacements must match the 1 A current rating, 200 V reverse voltage, and DO-204AL package type.
