GSIB1580N-M3/45

Overview

The GSIB1580N-M3/45 is a single-phase bridge rectifier from Vishay General Semiconductor, utilizing the GSIB-5S through-hole package. It features a maximum repetitive peak reverse voltage (VRRM) of 800 V and supports a maximum average forward rectified output current of 15 A at a case temperature of 107 °C, or 3.5 A at an ambient temperature of 25 °C without a heatsink. The device withstands a peak forward surge current (IFSM) of 300 A for a single sine wave. Electrical characteristics include a maximum instantaneous forward voltage drop of 0.95 V at 7.5 A and a maximum DC reverse current of 10 μA at 25 °C. The operating junction and storage temperature range spans from -55 °C to +150 °C.

Feature Summary

• Glass passivated chip junction provides high reliability and stability under varying thermal conditions.
• Thin single in-line package design facilitates efficient PCB mounting and space-constrained layouts.
• High surge current capability ensures robust performance during transient load events.
• High case dielectric strength of 2500 V RMS offers enhanced isolation protection.

Applications

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

Procurement Notes

Verify component authenticity by checking for the M3 suffix, which indicates halogen-free, RoHS-compliant construction meeting commercial grade standards. Confirm the presence of matte tin plated leads that are solderable per J-STD-002 and JESD 22-B102 specifications. Ensure the ordering code matches GSIB1580N-M3/45 to guarantee the correct 800 V rating and GSIB-5S package configuration.

Selection Notes

Select this component when an 800 V blocking voltage is required for single-phase rectification applications. The GSIB-5S package is suitable for through-hole mounting where a thin profile is necessary. Consider the thermal derating curves if operating above 25 °C ambient temperature; use an aluminum plate heatsink to achieve the rated 15 A current capacity. Verify that the application does not exceed the 300 A non-repetitive surge current limit.

Part Context

This part belongs to the GSIB15N series, which includes variants with different voltage ratings such as 200 V, 400 V, and 600 V. All members share identical physical dimensions, thermal characteristics, and current handling capabilities within the GSIB-5S package. The N-series designation typically denotes specific manufacturing optimizations compared to standard GSIB15 parts.

Replacement Considerations

Direct substitutes within the same family include GSIB1560N-M3/45 (600 V) and GSIB1540N-M3/45 (400 V), provided the circuit voltage requirements allow for lower ratings. Cross-family replacements must match the GSIB-5S footprint and meet or exceed the 15 A current and 800 V voltage specifications.

FAQ

What is the maximum thermal resistance from junction to ambient?

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

Does the M3 suffix affect the electrical performance?

No, the M3 suffix indicates halogen-free, RoHS-compliant materials and compliance with the JESD 201 class 1A whisker test, but it does not alter the electrical parameters.

What is the recommended mounting torque for the terminals?

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