GSIB1520-E3/45

Overview

The GSIB1520-E3/45 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 200 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 handles a peak forward surge current (IFSM) of 300 A and exhibits a maximum instantaneous forward voltage drop of 0.95 V at 7.5 A. Operating junction temperatures range from -55 °C to +150 °C.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• High surge current capability with 300 A rating
• Thin single in-line package design for compact mounting
• High case dielectric strength rated at 2500 V RMS

Applications

• AC/DC bridge full wave rectification for switching power supplies
• Home appliances requiring general-purpose rectification
• Office equipment power circuits
• Industrial automation applications

Procurement Notes

Verify component authenticity by checking for the Vishay marking on the plastic body and confirming the E3 suffix indicates lead-free compliance. Ensure the ordering code matches the specific voltage rating required for the circuit design. Cross-reference the document number 88644 to access the latest official datasheet specifications before finalizing procurement orders.

Selection Notes

Select this component when a 200 V blocking voltage is sufficient for the AC input line. Consider the thermal environment carefully; the 15 A rating requires a heatsink at 107 °C case temperature, while free-air operation limits current to 3.5 A. Verify that the PCB layout accommodates the GSIB-5S footprint and allows for the recommended mounting torque of 5.7 cm-kg.

Part Context

This part belongs to the GSIB15xx series of single-phase single in-line bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings such as GSIB1540, GSIB1560, and GSIB1580, all sharing the same physical GSIB-5S package dimensions and mechanical characteristics.

Replacement Considerations

Direct substitutes within the same series include GSIB1540-E3/45, GSIB1560-E3/45, and GSIB1580-E3/45. These alternatives offer higher voltage ratings of 400 V, 600 V, and 800 V respectively, while maintaining identical current handling capabilities and package styles.
