NSB8GT-M3/I

Single Diodes Overview

The NSB8GT-M3/I is a single standard recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 400 V and an average forward rectified current (Io) of 8 A per diode. The device utilizes glass passivation for general-purpose applications. Key electrical parameters include a forward voltage (Vf) of 1.1 V at 8 A, a reverse leakage current of 10 µA at 400 V, and a maximum surge current of 125 A. It operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

• Designed for surface-mount installation in TO-263AB packages

Single Diodes Applications

• General-purpose rectification in power supply circuits
• AC-to-DC conversion stages
• Battery charging systems

Single Diodes Procurement Notes

Verify the specific suffix 'M3/I' against official Vishay documentation to confirm RoHS compliance and lead-free status. Ensure the package designation matches TO-263AB requirements for your PCB layout. Confirm that the 400 V rating aligns with your circuit's peak inverse voltage demands. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Single Diodes Selection Notes

Select this component when a standard recovery time exceeding 500 ns is acceptable for the application frequency. The 8 A current rating suits moderate power levels where D2PAK thermal dissipation is sufficient. Consider the 400 V blocking voltage as the primary constraint for input line voltages. Verify that the 1.1 V forward drop meets efficiency targets compared to Schottky alternatives if lower loss is critical.

Single Diodes Part Context

This part belongs to Vishay's NSB series of glass-passivated standard recovery rectifiers. These devices are engineered for robustness in industrial and consumer electronics. The TO-263AB package provides a balance between high current handling and compact surface-mount footprint. The series supports various voltage ratings from 50 V to 1000 V.

Single Diodes Replacement Considerations

Consult official Vishay substitution guides for direct equivalents. Generic replacements must match the 400 V Vr, 8 A Io, and TO-263AB package constraints. Verify that substitute parts meet the same thermal and electrical specifications.
