GSIB156045

Overview

The GSIB156045 is a single-phase bridge rectifier from the Vishay GSIB15 series, housed in a GSIB-5S surface-mount package. It features a maximum repetitive peak reverse voltage (VRRM) of 600 V and supports a maximum average forward rectified output current (IF(AV)) of 3.5 A at an ambient temperature of 25 °C without a heatsink. The device exhibits a peak forward surge current capability of 300 A and a maximum instantaneous forward voltage drop of 0.95 V at 7.5 A. Operating junction temperatures range from -55 °C to +150 °C, with a typical thermal resistance (RθJA) of 22 °C/W.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• High case dielectric strength rated at 2500 V RMS
• Thin single in-line package design for compact mounting

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance status and packaging format. Confirm that the component meets RoHS requirements and passes the JESD 201 class 1A whisker test if required by the design specifications. Ensure the procurement channel sources directly from authorized distributors to maintain product integrity.

Selection Notes

Select this component when a 600 V blocking voltage is required for single-phase rectification. Evaluate the thermal management strategy based on the 22 °C/W junction-to-ambient thermal resistance for PCB mounting or the 1.5 °C/W junction-to-case resistance for heatsink applications. Verify that the 300 A surge current rating accommodates the circuit's transient load conditions.

Part Context

This part belongs to the GSIB15 series of single-phase single in-line bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings, specifically 200 V, 400 V, 600 V, and 800 V, all sharing the same GSIB-5S package and general electrical characteristics.

Replacement Considerations

Compatible substitutes within the same family include the GSIB1520, GSIB1540, and GSIB1580. These parts share identical physical dimensions and thermal profiles but differ in their maximum repetitive peak reverse voltage ratings.
