GBLA005-E3/51

Overview

The GBLA005-E3/51 is a glass-passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum average forward rectified output current of 4.0 A at a case temperature of 50 °C and 3.0 A at an ambient temperature of 40 °C when mounted on a PCB. The device supports a maximum repetitive peak reverse voltage (VRRM) of 50 V, with corresponding RMS and DC blocking voltages of 35 V and 50 V, respectively. It withstands a peak forward surge current (IFSM) of 120 A for a single sine wave superimposed on rated load. The component operates within a junction and storage temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivation provides long-term stability and protects the junction against mechanical stress.
• Molding compound meets UL 94 V-0 flammability rating for enhanced safety.
• Terminals are matte tin plated, ensuring solderability per J-STD-002 and JESD 22-B102 standards.
• E3 suffix compliance ensures adherence to JESD 201 class 1A whisker test requirements.

Applications

• AC/DC bridge full wave rectification in monitors
• Power supply circuits in televisions and printers
• Switching mode power supplies (SMPS) and adapters
• Audio equipment and home appliances

Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as the /51 designation indicates delivery in anti-static PVC trays with a base quantity of 400 units. Confirm RoHS compliance status and material categorization definitions via official Vishay documentation before finalizing procurement specifications.

Selection Notes

Select this component for general-purpose rectification where a 50 V reverse voltage rating and 4 A continuous current capability are required. Ensure thermal management accounts for the specified derating curves based on whether the unit is heat-sink mounted or PCB mounted. Verify that the operating environment remains within the -55 °C to +150 °C junction temperature limits.

Part Context

This part belongs to the GBLAxx series of glass-passivated single-phase bridge rectifiers. The datasheet explicitly identifies the GBLA005-E3/51 as End of Life, recommending the GBL005E series as the alternative device. The GBL package offers an in-line circuit configuration suitable for printed circuit board mounting.

Replacement Considerations

The official alternative device listed in the datasheet is the GBL005E series. Engineers should evaluate the GBL005E components as direct replacements due to the End of Life status of the GBLA005-E3/51.
