GBU6J-E3/45

Overview

The GBU6J-E3/45 is a glass passivated single-phase bridge rectifier from Vishay General Semiconductor. It provides a maximum repetitive peak reverse voltage of 600 V and an average forward rectified output current of 6.0 A at a case temperature of 90 °C. The device features a peak forward surge current capability of 175 A for a single sine wave superimposed on rated load. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.0 V at 6.0 A and a maximum DC reverse current of 5.0 μA at 25 °C. It operates within a junction and storage temperature range of -55 to +150 °C.

Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. The E3 suffix indicates RoHS compliance and halogen-free status for commercial grade products. Confirm that the /45 package code corresponds to the required tube delivery mode containing twenty units per tube. Ensure the component selection aligns with the intended thermal management strategy for the target application environment.

Selection Notes

Select this component based on the 600 V reverse voltage requirement and 6.0 A continuous current capacity. Evaluate the thermal resistance parameters to ensure adequate heat dissipation under expected operating loads. Verify that the PCB layout accommodates the GBU package dimensions and lead spacing. Consider the 175 A surge current rating when designing protection circuits for inductive or capacitive loads.

Part Context

This part belongs to the GBU6 series of single-phase bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 6.0 A current rating. The GBU6J specifically denotes the 600 V version within this standardized product family.

Replacement Considerations

Direct replacement options within the same series include GBU6G (400 V) or GBU6K (800 V), provided the voltage rating meets the circuit requirements. Other manufacturers offering equivalent GBU packages should be evaluated for matching electrical specifications and physical dimensions.
