1N6481-E3/97

Overview

The Vishay 1N6481-E3/97 is a surface-mount glass passivated junction rectifier featuring the Superectifier structure. It provides a maximum average forward rectified current of 1.0 A and a peak forward surge current of 30 A. The device offers a maximum repetitive peak reverse voltage of 400 V, with a maximum instantaneous forward voltage of 1.1 V at 1.0 A. Maximum DC reverse current is 10 μA at rated blocking voltage. Operating junction temperature ranges from -65 °C to +175 °C.

Feature Summary

• Superectifier structure designed for high reliability under demanding conditions
• Glass passivated junction providing low leakage current and low forward voltage drop
• High forward surge capability suitable for transient load protection
• Meets MSL level 1 per J-STD-020 standards for automated placement

Applications

• General purpose rectification in power supplies
• Freewheeling diodes for consumer electronics
• Inverter and converter circuits
• Automotive electronic systems
• Telecommunication equipment

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status and package orientation markings. Validate ordering suffixes match required reel quantities and tape dimensions. Ensure storage conditions maintain moisture sensitivity level integrity prior to soldering.

Selection Notes

Select this component when a 400 V reverse voltage rating is required alongside a 1.0 A continuous current capacity. The GL41 (DO-213AB) package facilitates automated surface-mount assembly processes. Consider thermal resistance characteristics for heat dissipation requirements in enclosed environments. Verify compatibility with operating temperature ranges extending up to 175 °C.

Part Context

This part belongs to the Vishay 1N6478 through 1N6484 series of surface-mount rectifiers. All variants share identical electrical ratings except for the maximum repetitive peak reverse voltage, which varies across the series. The 1N6481 specifically designates the 400 V rating within this standardized product family.

Replacement Considerations

Direct substitutes include other Vishay parts within the same series sharing the DO-213AB package and 400 V rating, such as 1N6481-E3/96. Cross-manufacturer replacements must match the 1.0 A current, 400 V reverse voltage, and physical footprint constraints.
