GBLA08

Overview

The GBLA08 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features an average forward rectified current of 4 A and a maximum repetitive peak reverse voltage of 800 V. The device utilizes silicon technology and is housed in a GBL-4 through-hole package. Key electrical parameters include a forward voltage of 1 V at 4 A, a reverse leakage current of 5 µA at 800 V, and a maximum surge current of 120 A. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Single-phase bridge rectification using silicon technology
• Through-hole mounting via GBL-4 plastic case
• High thermal stability with extended operating temperature range

Applications

• General purpose AC to DC power supply conversion
• In-line bridge rectifier circuits
• Low to medium current electronic equipment power stages

Procurement Notes

Verify the specific manufacturer designation, as the GBLA08 part number is primarily associated with Vishay General Semiconductor. Confirm if the requested unit is sourced from Taiwan Semiconductor or if a cross-manufacturer equivalent is intended. Ensure the datasheet matches the 4 A / 800 V specifications provided for the Taiwan Semiconductor variant to avoid functional mismatches during integration.

Selection Notes

Select this component when a 4 A continuous current rating and 800 V blocking voltage are required for through-hole applications. The GBL-4 package offers a compact footprint suitable for standard PCB layouts. Consider the 120 A surge current capability for inrush protection scenarios. Verify thermal management requirements given the 150°C maximum junction temperature limit.

Part Context

The GBLA series represents a line of general-purpose bridge rectifiers designed for efficient AC-to-DC conversion. The GBLA08 specifically denotes the 800 V voltage rating variant within this family. These devices are engineered for reliability in standard industrial and consumer electronics environments, providing a robust solution for power supply input stages where moderate current handling is sufficient.

Replacement Considerations

Cross-reference with Vishay GBLA08-E3/45 for identical electrical specifications. Check Taiwan Semiconductor GBLA005HD2 for lower voltage alternatives. Verify pinout compatibility with the GBL-4 package before substitution.
