1N4933L-T

Overview

The 1N4933L-T is a single-phase, half-wave fast recovery rectifier manufactured by Diodes Incorporated. It features a diffused junction silicon construction housed in a DO-41 plastic case with bright tin-plated leads. The device supports an average rectified output current of 1.0 A at +75°C and withstands a peak repetitive reverse voltage of 50 V. Key electrical characteristics include a maximum forward voltage drop of 1.2 V at 1.0 A, a peak reverse current of 5 µA at rated DC blocking voltage, and a reverse recovery time of 200 ns. It offers a non-repetitive peak forward surge current rating of 30 A and operates within a temperature range of -65 to +150 °C.

Feature Summary

• Fast switching capability designed for high efficiency applications
• High current capability combined with low forward voltage drop
• Low reverse leakage current performance
• Surge overload rating supporting up to 30 A peak current

Applications

• General purpose rectification in power supplies
• Free wheeling diode circuits
• Polarity protection circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details, as standard designations may vary. Confirm RoHS compliance status and lead-free finish requirements prior to procurement. Ensure that the component meets all applicable environmental directives relevant to your manufacturing region. Cross-reference the datasheet revision number to ensure compatibility with your design specifications.

Selection Notes

Select this component for applications requiring reliable rectification with moderate speed switching characteristics. Consider the thermal resistance and derating curves when designing for high ambient temperatures. Evaluate the package size constraints against the available DO-41 footprint. Verify that the 50 V reverse voltage rating provides sufficient margin for the circuit's peak operating voltages.

Part Context

This part belongs to the 1N4933 through 1N4937 series of fast recovery rectifiers from Diodes Incorporated. These devices share similar mechanical and electrical profiles but differ primarily in their peak repetitive reverse voltage ratings. The series utilizes a standardized DO-41 axial leaded package suitable for through-hole mounting. This family is widely used in general-purpose electronics where cost-effective rectification is required.

Replacement Considerations

The datasheet explicitly recommends using the RS1A through RS1J series instead of this product for new designs. Verify if the RS1A variant meets the specific voltage and current requirements of your application as a direct functional substitute.
