1N4947GPHE3/54

Overview

The Vishay 1N4947GPHE3/54 is a glass-passivated junction fast switching plastic rectifier designed for high reliability. It features a Superectifier structure and cavity-free construction within a DO-41 (DO-204AL) package. The device supports a maximum repetitive peak reverse voltage of 800 V and a maximum average forward rectified current of 1.0 A at 55 °C. Key electrical characteristics include a maximum instantaneous forward voltage of 1.3 V, a maximum DC reverse current of 1.0 μA at rated blocking voltage, and a typical reverse recovery time of 250 ns. It withstands a peak forward surge current of 25 A and operates across a temperature range of -65 to +175 °C.

Feature Summary

• Glass-passivated junction with cavity-free construction for enhanced reliability
• Superectifier structure optimized for high efficiency in fast switching applications
• High forward surge capability supporting demanding transient loads

Applications

• Fast switching rectification in power supplies
• Inverter and converter circuits
• Freewheeling diodes for consumer electronics
• Telecommunication equipment

Procurement Notes

Verify the component status before procurement as this series is designated 'Not for New Designs'. Confirm that the E3 suffix indicates RoHS compliance and JESD 201 class 1A whisker test meeting. Ensure the specific ordering code matches the required delivery mode, such as paper tape and reel or ammo pack packaging, to align with manufacturing requirements.

Selection Notes

Select this component when an 800 V reverse voltage rating is required alongside a 1.0 A continuous current capacity. The 250 ns reverse recovery time makes it suitable for higher frequency switching compared to standard recovery diodes. Verify thermal management needs against the 55 °C/W thermal resistance and derating curves if operating above ambient temperatures.

Part Context

This part belongs to the Vishay SUPERECTIFIER® family, which includes variants ranging from 200 V to 1000 V reverse voltage ratings. The 1N4947GP variant specifically addresses the 800 V requirement within this lineup. All parts in this series share identical mechanical dimensions and general electrical profiles, differing primarily in their breakdown voltage specifications.

Replacement Considerations

Direct substitutes within the same datasheet include the 1N4946GP (600 V) and 1N4948GP (1000 V), provided the voltage margin allows adjustment.
