GBL08HD2G

Overview

The GBL08HD2G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor. It utilizes glass passivated junction technology for high reliability and low leakage current. The device features an isolated case design suitable for printed circuit board mounting. Key electrical parameters include a maximum average forward rectified current of 8 A and a repetitive peak reverse voltage of 800 V. The unit operates within a temperature range of -55 °C to +150 °C. It is housed in a GBU-4 package, which provides high dielectric strength between the terminals and the base plate.

Feature Summary

• Glass passivated junction construction ensures high reliability and stability under varying thermal conditions.
• Isolated case design allows for direct mounting to heat sinks without additional insulating hardware.
• High surge current capability supports robust performance during transient load events.

Applications

• General purpose AC-to-DC power supply circuits
• Battery charging systems requiring high voltage isolation
• Industrial control equipment power stages

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and specific ordering suffixes match project requirements. Request original datasheets to validate electrical ratings against application needs. Ensure storage conditions adhere to semiconductor handling standards to prevent moisture sensitivity damage prior to assembly.

Selection Notes

Select this component when an 8 A current rating and 800 V blocking voltage are required in a through-hole GBU package. Compare forward voltage drop characteristics against thermal management constraints. Verify that the operating temperature range meets the environmental specifications of the target enclosure. Consider physical footprint compatibility with existing PCB layouts designed for standard GBL/GBU series components.

Part Context

This part belongs to the GBL series of glass passivated single-phase bridge rectifiers from Taiwan Semiconductor. The series offers various voltage ratings from 50 V to 1000 V while maintaining consistent 8 A current capacity. The GBL08HD2G specifically addresses applications requiring higher voltage isolation compared to lower-rated variants like the GBL005 or GBL06.

Replacement Considerations

Direct pin-compatible substitutes may include other manufacturers' 8 A, 800 V bridge rectifiers in GBU-4 packages. Verify equivalent forward voltage and surge current ratings before substitution. Cross-reference mechanical dimensions to ensure fit within the designated PCB area.
