1N4936-TP

Overview

The MCC 1N4936-TP is a fast recovery rectifier diode housed in the DO-41 axial leaded package. It features a maximum repetitive peak reverse voltage of 400V and supports an average forward current of 1.0A at 55°C ambient temperature. The device exhibits a maximum instantaneous forward voltage of 1.3V at 1.0A and a typical junction capacitance of 15pF. Electrical characteristics include a maximum DC reverse current of 5.0μA at rated voltage (25°C) and a maximum reverse recovery time of 200ns.

Feature Summary

• Fast switching capability for high efficiency applications
• Low leakage current and low cost design
• Diffused junction construction with low forward voltage drop
• Epoxy casing meets UL 94 V-0 flammability rating

Applications

• High frequency rectification circuits
• Free wheeling diodes in inductive loads
• General purpose rectification in power supplies

Procurement Notes

Verify the specific ordering suffix to confirm packaging format, as TP indicates tape and reel while BP denotes bulk packaging. Ensure compliance requirements such as RoHS status and halogen-free availability are confirmed against the final part number before procurement. Cross-reference datasheet electrical limits with circuit operating conditions to ensure adequate thermal and voltage margins.

Selection Notes

Select this component when a 400V blocking voltage and 1A continuous current rating are required in a standard axial package. Consider the 200ns reverse recovery time for switching speed requirements. Evaluate thermal resistance constraints, noting the 30°C/W junction-to-lead rating, to determine appropriate heat dissipation methods for the target application environment.

Part Context

This component belongs to the 1N4933 through 1N4937 series of fast recovery rectifiers manufactured by Micro Commercial Components. The series shares common mechanical dimensions and general electrical characteristics, differentiated primarily by their maximum repetitive peak reverse voltage ratings ranging from 50V to 600V. The DO-41 package provides a standardized footprint for through-hole mounting.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N4936 variants or equivalent fast recovery diodes with matching 400V reverse voltage and 1A forward current ratings. Verify that replacement parts meet the same reverse recovery time and forward voltage specifications to maintain circuit performance.
