1N6481HE3_A/I

Overview

The 1N6481HE3_A/I is a standard rectifier diode manufactured by Vishay General Semiconductor. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 1 A. The device utilizes a glass passivation junction for reliability and is housed in a DO-213AB MELF surface-mount package. It is designed for general-purpose rectification applications requiring robust performance in compact form factors.

Feature Summary

• Glass passivated junction for enhanced environmental stability
• Surface mount MELF package design for automated assembly
• High surge current capability for transient protection

Applications

• General purpose rectification in power supplies
• Reverse polarity protection circuits
• Freewheeling diodes in inductive load switching

Procurement Notes

Verify the specific suffix designation, as variants such as HE3/96 or HE3/97 may have different packaging or availability statuses. Confirm that the component meets RoHS directives if required for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount solution is required for 400V applications. Ensure the PCB footprint matches the DO-213AB MELF specification. Consider thermal management requirements based on the expected forward current and ambient operating conditions during circuit design.

Part Context

This diode belongs to Vishay's standard rectifier family, offering a balance of electrical performance and mechanical durability. The MELF format provides a hermetic seal suitable for harsh environments while maintaining a low profile for modern electronic assemblies.

Replacement Considerations

The 1N6481HE3_A/I is listed as obsolete. Recommended substitutes include the 1N6481HE3_A/I from alternative sourcing channels or equivalent MELF rectifiers with matching 400V and 1A ratings.
