1N4933-TP

Overview

The 1N4933-TP is a silicon fast recovery rectifier diode manufactured by Micro Commercial Components (MCC). It features a maximum average forward current of 1.0 A and a maximum repetitive peak reverse voltage of 50 V. The device exhibits a maximum instantaneous forward voltage of 1.3 V at 1.0 A, with a typical junction capacitance of 15 pF measured at 1.0 MHz and 4.0 V reverse bias. Maximum DC reverse current is specified as 5.0 µA at 25°C and 100 µA at 125°C. The component utilizes a DO-41 axial leaded package and supports an operating temperature range from -55°C to +150°C.

Feature Summary

• Fast switching capability with a maximum reverse recovery time of 200 ns
• Low leakage current characteristics across specified temperature ranges
• Epoxy casing meets UL 94 V-0 flammability rating

Applications

• High frequency rectification circuits
• Free-wheeling diodes in power supplies
• General purpose rectification in electronic equipment

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard part number includes the -TP suffix indicating tape and reel packaging containing 5,000 pieces per reel. Halogen-free variants are available by adding the -HF suffix to the part number. Confirm compliance requirements such as RoHS status and moisture sensitivity level prior to procurement to ensure alignment with manufacturing standards.

Selection Notes

Select this component for applications requiring a 50 V blocking voltage and 1 A continuous current handling. Ensure the thermal resistance of 30°C/W junction-to-lead is accommodated within the system design. Verify that the 200 ns reverse recovery time meets the circuit's switching speed requirements. Consider the DO-41 through-hole package constraints during PCB layout planning.

Part Context

This component belongs to the 1N4933 through 1N4937 series of fast recovery rectifiers produced by MCC. The series covers voltage ratings from 50 V to 600 V while maintaining a consistent 1.0 A average forward current rating. The 1N4933 variant specifically addresses low-voltage high-speed rectification needs within this standardized product family.

Replacement Considerations

Compatible substitutes include the onsemi 1N4933RLG and Rectron Semiconductor 1N4933. Verify pinout compatibility and electrical parameter equivalence before substitution.
