GSIB15A80N-M3/45

Overview

The GSIB15A80N-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 800 V and delivers a maximum average forward rectified output current of 15 A at a case temperature of 107 °C. It features a peak forward surge current capability of 200 A and a maximum instantaneous forward voltage drop of 1.0 V per diode at 7.5 A. The component operates within a junction and storage temperature range of -55 to +150 °C.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance details. The M3 suffix indicates halogen-free, RoHS-compliant material categorization and commercial grade status. Confirm that the base part number aligns with the required voltage rating before procurement. Ensure technical specifications match the application requirements.

Selection Notes

Select this component based on the 800 V reverse voltage requirement and 15 A average forward current capacity. Consider the thermal resistance characteristics when designing heatsinking solutions. Verify that the operating temperature range meets the environmental conditions of the target application. Evaluate the physical dimensions of the GSIB-5S package for PCB layout compatibility.

Part Context

This component belongs to the GSIB15A series of single-phase single in-line bridge rectifiers from Vishay General Semiconductor. The series includes variants with different voltage ratings, such as 200 V, 400 V, and 600 V. All members share similar electrical characteristics and mechanical packaging, differing primarily in their maximum repetitive peak reverse voltage capabilities.

Replacement Considerations

Direct substitutes include other GSIB15A series parts like GSIB15A60N or GSIB15A40N if lower voltage ratings are acceptable. Cross-brand replacements must match the 15 A current rating, 800 V blocking voltage, and GSIB-5S package footprint. Verify thermal performance and forward voltage drop similarities.

FAQ

What is the maximum thermal resistance from junction to ambient?

The maximum thermal resistance from junction to ambient (RθJA) is 22 °C/W when units are mounted on a PCB without a heatsink.

Does the M3 suffix affect the electrical function?

No, the M3 suffix denotes material compliance, specifically halogen-free, RoHS-compliant materials, and meeting JESD 201 class 1A whisker test requirements. It does not change the electrical parameters.

What is the recommended mounting torque?

The recommended mounting torque is 5.7 cm-kg (5 in-lbs), with a maximum limit of 10 cm-kg (8.8 in-lbs).
