1N4935-AP

Overview

The MCC 1N4935-AP is a single-element silicon fast recovery rectifier diode housed in the DO-41 axial leaded package. It features a maximum repetitive peak reverse voltage of 200V and an average forward rectified current rating 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. Key electrical parameters include a maximum reverse recovery time of 200ns, a peak forward surge current capability of 30A, and a maximum DC reverse leakage current of 5μA at rated voltage.

Feature Summary

• Glass passivated junction construction for high reliability
• Fast switching characteristics with low reverse recovery time
• Low leakage current performance across operating temperatures
• Epoxy material meets UL 94 V-0 flammability ratings

Applications

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

Procurement Notes

Verify that the part number suffix matches the required packaging configuration. The -AP suffix specifically denotes Ammo Box packing containing 5,000 pieces per box. Confirm compliance requirements such as RoHS status or halogen-free specifications if needed by adding appropriate suffixes like -HF. Ensure sourcing from authorized distributors to guarantee genuine components and full traceability.

Selection Notes

Select this component when a 200V blocking voltage and 1A continuous current are required in a standard axial package. Consider the 200ns reverse recovery time for applications requiring faster switching than standard general-purpose diodes. Evaluate thermal derating curves for operation above 55°C ambient temperature to ensure the 1A rating remains within safe limits.

Part Context

This device belongs to the 1N4933 through 1N4937 series of fast recovery rectifiers manufactured by Micro Commercial Components. The series covers voltage ratings from 50V to 600V while maintaining a consistent 1A current rating and DO-41 package form factor. The 1N4935 variant specifically targets applications requiring 200V reverse voltage blocking capability.

Replacement Considerations

Compatible substitutes include Vishay 1N4935GP and Sensitron 1N4935-GT3. Verify that replacement parts maintain identical DO-41 mechanical dimensions and match the 200V reverse voltage and 1A forward current specifications.
