GSIB2020N-M3/45

Overview

The Vishay GSIB2020N-M3/45 is a single-phase bridge rectifier in the GSIB-5S through-hole package. It features a maximum repetitive peak reverse voltage of 200 V and a maximum average forward rectified output current of 20 A at a case temperature of 87 °C, or 3.5 A at an ambient temperature of 25 °C without a heatsink. The device has a peak forward surge current rating of 240 A and a maximum instantaneous forward voltage drop of 1.0 V at 7.5 A. Operating junction and storage temperatures range from -55 °C to +150 °C.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• High surge current capability with 240 A peak rating
• Thin single in-line package design for compact mounting
• High case dielectric strength rated at 2500 V RMS

Applications

• AC/DC bridge full wave rectification for switching power supplies
• Rectification circuits in home appliances
• Power stages in office equipment
• Industrial automation applications

Procurement Notes

Verify component authenticity by checking for the M3 suffix, which indicates halogen-free, RoHS-compliant construction and commercial grade quality. Confirm that the matte tin plated leads meet J-STD-002 solderability standards. Ensure the ordering code matches the specific voltage variant required, as the datasheet covers multiple ratings within the same physical package family.

Selection Notes

Select this component based on the 200 V reverse voltage requirement and the expected load current profile. If operating without a heatsink at 25 °C ambient, limit the average current to 3.5 A; otherwise, utilize an aluminum plate heatsink to achieve the full 20 A rating. Verify thermal resistance requirements against the application's heat dissipation capabilities.

Part Context

This part belongs to the GSIB series of single-phase single in-line bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings (GSIB2040N, GSIB2060N, GSIB2080N) sharing the identical GSIB-5S package and mechanical dimensions. The M3 designation signifies compliance with modern environmental directives.

Replacement Considerations

Direct substitutes within the same Vishay family include GSIB2040N-M3/45, GSIB2060N-M3/45, and GSIB2080N-M3/45. These parts share the same package and current ratings but offer higher reverse voltage capabilities of 400 V, 600 V, and 800 V respectively.
