NSB8DT-E3/81

Single Diodes Overview

The NSB8DT-E3/81 is a standard recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an 8 A average forward current rating and a 200 V maximum repetitive peak reverse voltage. The device utilizes a TO-263AB (D2PAK) surface-mount package with three leads. Key electrical specifications include a maximum forward voltage of 1.1 V at 8 A and a maximum non-repetitive peak surge current of 125 A. It operates within a junction temperature range of -55 °C to +150 °C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free markings on the physical package. Check for obsolescence notices as this part may be discontinued. Ensure storage conditions meet semiconductor handling standards to prevent moisture sensitivity damage prior to reflow soldering.

Single Diodes Selection Notes

Select this component when a single common cathode configuration is required in a D2PAK footprint. Compare against NSB8BT-E3/81 for higher voltage ratings or NSB8JT-E3/81 for increased voltage tolerance. Verify that the 200 V reverse voltage rating exceeds the peak inverse voltage in the target circuit. Ensure the thermal management design supports the 8 A continuous current capability without exceeding junction temperature limits.

Single Diodes Part Context

This component belongs to the NSB8 series of standard recovery rectifiers from Vishay. The series offers various voltage ratings including 50 V, 100 V, 200 V, 300 V, 400 V, 500 V, and 600 V options.
