FE3A

Single Diodes Overview

The Diotec Semiconductor FE3A is a superfast recovery rectifier diode designed for high-speed switching applications. It features an average forward current rating of 3 A and a peak forward surge current capability of 125 A or 135 A depending on the frequency. The device has a maximum reverse voltage rating of 50 V and a low forward voltage drop of less than 0.98 V at 3 A. Key electrical characteristics include a reverse recovery time under 50 ns, leakage current below 5 µA, and a typical junction capacitance of 15 pF. It operates within a temperature range of -50°C to +175°C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance and halogen-free status as stated in documentation. Ensure ordering suffixes match required packaging formats. Validate that the specific batch meets commercial/industrial grade reliability standards before integration into final assemblies.

Single Diodes Selection Notes

Select this component when superfast recovery characteristics are required for efficient high-frequency operation. Consider the 3 A current rating and 50 V blocking voltage for appropriate circuit matching. Evaluate thermal management requirements given the 175°C maximum junction temperature limit. Compare forward voltage and reverse recovery parameters against alternative superfast rectifiers to ensure optimal system performance.

Single Diodes Part Context

The FE3A belongs to Diotec's FE series of superfast recovery rectifier diodes. This family includes variants like FE3B, FE3D, and FE3G, which share similar package types but differ in voltage ratings and forward voltage characteristics. These components are manufactured using silicon planar technology and are intended for general commercial and industrial electronic applications requiring reliable high-speed rectification.

Single Diodes Replacement Considerations

Direct substitutes within the same series include FE3B, FE3D, and FE3G, provided their respective voltage ratings align with circuit requirements. Cross-brand replacements must match the DO-201AD package, 3 A current rating, <50 ns recovery time, and 50 V minimum reverse voltage specification to maintain equivalent electrical performance.
