Overview
The Vishay GBU8J-M3/51 is a glass passivated single-phase bridge rectifier in the GBU series. It features a maximum repetitive peak reverse voltage (VRRM) of 600 V and a maximum average forward rectified output current (IF(AV)) of 8.0 A at a case temperature of 60 °C. The device supports a peak forward surge current (IFSM) of 200 A for a single sine wave superimposed on rated load. Electrical characteristics include a maximum instantaneous forward voltage drop (VF) of 1.0 V at 8.0 A and a maximum DC reverse current (IR) 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 provides mechanical strength and long-term stability
- High surge current capability suitable for demanding power applications
- High case dielectric strength rated at 1500 V RMS
Applications
- AC/DC bridge full wave rectification for monitors, TVs, and printers
- Power supply and switching mode power supply designs
- Adapter, audio equipment, and home appliances applications
Procurement Notes
Verify the specific ordering suffix against official documentation before procurement. The M3 suffix indicates halogen-free, RoHS-compliant commercial grade material categorization. Confirm that the /51 designation corresponds to the required paper tray delivery mode with a base quantity of 250 units. Ensure compliance with regional regulatory requirements matches the product specifications.
Selection Notes
Select this component when a 600 V blocking voltage and 8 A continuous current rating are required for through-hole mounting. The GBU package offers high thermal performance with a typical thermal resistance of 4.0 °C/W from junction to case. Verify that the PCB layout accommodates the specified lead length and copper pad dimensions for optimal heat dissipation during operation.
Part Context
This part belongs to the Vishay GBU8 family of glass passivated single-phase bridge rectifiers. The series includes variants with different voltage ratings ranging from 50 V to 1000 V, all sharing the same 8 A current rating and GBU package style. The GBU8J specifically denotes the 600 V variant within this standardized lineup.
Replacement Considerations
Other GBU8 series parts such as GBU8G or GBU8K share identical electrical parameters except for their reverse voltage ratings. Ensure the replacement part meets or exceeds the 600 V requirement. Verify that the physical footprint and pinout remain compatible with the existing design.
