GBU4J-E3/51

Overview

The GBU4J-E3/51 is a glass passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the GBU surface-mount package and provides a maximum repetitive peak reverse voltage (VRRM) of 600 V, with a corresponding maximum RMS voltage of 420 V and DC blocking voltage of 600 V. The device supports a maximum average forward rectified output current of 4.0 A at a case temperature of 100 °C, or 3.0 A in free air at 40 °C. Peak forward surge current capability is rated at 150 A for a single sine wave superimposed on rated load. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.0 V at 4.0 A and a maximum DC reverse current of 5.0 μA at 25 °C. The component operates within a junction and storage temperature range of -55 to +150 °C.

Feature Summary

• Glass passivation protects the junctions against mechanical stresses
• High surge current capability suitable for demanding power applications
• High case dielectric strength rated at 1500 V RMS
• Ideal for printed circuit board mounting

Applications

• AC/DC bridge full wave rectification
• Switching mode power supplies
• Monitors and televisions
• Printers and adapters
• Audio equipment and home appliances

Procurement Notes

Verify the specific ordering suffix to confirm packaging details. The /51 designation indicates delivery in paper trays with a base quantity of 250 units. Confirm that the E3 suffix aligns with requirements for RoHS compliance and lead-free terminals. Cross-reference the document number 88614 to ensure access to the latest electrical specifications and mechanical data before finalizing procurement orders.

Selection Notes

Select this component when a 600 V rating is required for single-phase bridge rectification. Ensure the application allows for adequate thermal management, as the average forward current derates significantly based on ambient temperature and heatsinking conditions. Verify that the GBU footprint matches the PCB layout constraints and that the 150 A surge current rating exceeds the expected inrush currents of the target circuit.

Part Context

This part belongs to the GBU4 series of glass passivated single-phase bridge rectifiers from Vishay. The series includes variants with different voltage ratings such as GBU4A (50 V), GBU4B (100 V), GBU4D (200 V), GBU4G (400 V), GBU4K (800 V), and GBU4M (1000 V). All members share identical physical dimensions, current ratings, and thermal characteristics, differing only in their maximum repetitive peak reverse voltage capabilities.

Replacement Considerations

Direct substitutes within the same family include GBU4J-E3/45, which shares identical electrical parameters but differs in packaging format. Other voltage-rated variants like GBU4G or GBU4K may be used if higher voltage margins are acceptable, provided the current and thermal requirements remain within the shared specifications.
