GSIB1520N-M3/45

Overview

The GSIB1520N-M3/45 is a single-phase single in-line bridge rectifier manufactured by Vishay General Semiconductor. It utilizes glass-passivated chip junctions and is housed in the compact GSIB-5S package. The device supports a maximum repetitive peak reverse voltage of 200 V, with a maximum RMS voltage of 140 V and DC blocking voltage of 200 V. It provides a maximum average forward rectified output current of 15 A at a case temperature of 107 °C, or 3.5 A when mounted on a PCB without a heatsink. Peak forward surge current capability reaches 300 A for a single sine wave superimposed on rated load. The maximum instantaneous forward voltage drop per diode is 0.95 V at an IF of 7.5 A. Reverse current is limited to 10 μA at 25 °C and 250 μA at 125 °C. Operating junction and storage temperatures range from -55 °C to +150 °C.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and halogen-free status associated with the M3 suffix. Ensure ordering codes match specific thermal and packaging requirements. Validate datasheet revision dates against production batches. Cross-reference UL recognition file number E54214 for safety certification needs.

Selection Notes

Select based on required reverse voltage ratings and thermal management capabilities. Evaluate derating curves for ambient temperature conditions and heatsinking strategies. Compare thermal resistance values between junction-to-case and junction-to-ambient configurations. Consider physical mounting torque limits and lead solderability standards during integration.

Part Context

This component belongs to the GSIB1520N series, which includes variants with different voltage ratings such as GSIB1540N, GSIB1560N, and GSIB1580N. All share identical current ratings and package styles but differ in peak reverse voltage specifications. The M3 designation indicates halogen-free, RoHS-compliant construction with matte tin plated leads.

Replacement Considerations

Direct substitutes within the same family include GSIB1540N, GSIB1560N, and GSIB1580N if higher voltage ratings are acceptable. Verify pinout compatibility and thermal characteristics before implementation.
