GSIB2540-E3/45

Overview

The GSIB2540-E3/45 is a single-phase single in-line bridge rectifier from Vishay General Semiconductor, utilizing the GSIB-5S package. It features a maximum average forward rectified output current of 25 A at a case temperature of 98 °C and 3.5 A at an ambient temperature of 25 °C without a heatsink. The device supports a maximum repetitive peak reverse voltage (VRRM) of 400 V and a maximum DC blocking voltage of 400 V. Peak forward surge current capability is rated at 350 A for a single sine wave superimposed on rated load. The maximum instantaneous forward voltage drop is 1.0 V at an forward current of 12.5 A. Reverse leakage current is specified as 10 μA at 25 °C and 350 μA at 125 °C when tested at the rated DC blocking voltage.

Procurement Notes

Verify the specific ordering suffix /45 against the manufacturer's current documentation to confirm the delivery mode and base quantity. The datasheet indicates this suffix corresponds to tube packaging with a base quantity of 20 units per tube. Ensure that the RoHS compliance status and material categorization definitions are reviewed via the provided Vishay documentation links prior to final procurement decisions.

Selection Notes

Select this component when a 400 V reverse voltage rating is required for single-phase rectification. Consider the thermal resistance values, specifically 1.0 °C/W junction-to-case and 22 °C/W junction-to-ambient, to determine appropriate heatsinking or PCB mounting strategies. Verify that the operating junction temperature range of -55 to +150 °C meets the environmental requirements of the target application.

Part Context

This part belongs to the GSIB25xx series of single-phase single in-line bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings: GSIB2520 (200 V), GSIB2540 (400 V), GSIB2560 (600 V), and GSIB2580 (800 V). All variants share the same GSIB-5S package style and similar current handling capabilities, differing primarily in their maximum repetitive peak reverse voltage specifications.

Replacement Considerations

Direct substitutes within the same family include GSIB2520-E3/45, GSIB2560-E3/45, and GSIB2580-E3/45, provided the voltage rating aligns with circuit requirements. Cross-manufacturer replacements must match the GSIB-5S footprint, 25 A current rating, 400 V reverse voltage, and pinout configuration.
