GBU8D-M3/45

Overview

The GBU8D-M3/45 is a single-phase bridge rectifier manufactured by Vishay Semiconductors. It features an average forward rectified current of 8 A and a maximum repetitive peak reverse voltage of 200 V. The device utilizes glass passivation for junction protection and is housed in a GBU (DO-201AB) through-hole package. Key electrical parameters include a maximum RMS diode voltage of 140 V, a maximum DC blocking voltage of 200 V, and a maximum non-repetitive peak forward surge current of 200 A at 60 Hz. The component operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivated junction provides high reliability and long-term stability under various operating conditions.

Applications

• AC to DC power supply circuits
• Battery charging systems
• General-purpose full-wave rectification

Procurement Notes

Verify the specific suffix /45 against the manufacturer datasheet to confirm tube packaging requirements. Ensure the M3 designation aligns with RoHS compliance standards required for the target assembly. Cross-reference the GBU package dimensions with PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this component when an 8 A current rating and 200 V reverse voltage capability are required for through-hole mounting. The GBU package offers robust mechanical stability for industrial applications. Verify that the 200 A surge current rating meets the inrush current demands of the specific load circuit during startup phases.

Part Context

This part belongs to the Vishay GBU8 series of glass passivated bridge rectifiers. The series is designed for general-purpose AC-to-DC conversion in compact form factors. The GBU8D variant specifically denotes the 200 V blocking voltage rating within the family, distinguishing it from higher or lower voltage options like the GBU8G or GBU8F.

Replacement Considerations

Direct substitutes include other 8 A, 200 V single-phase bridge rectifiers in the GBU package. Equivalent parts from other manufacturers must match the 8 A average forward current, 200 V peak reverse voltage, and physical pinout configuration to ensure compatibility without PCB redesign.
