GBU603

Overview

The GBU603 is a single-phase bridge rectifier from the Taiwan Semiconductor GBU6 series, rated for a repetitive peak reverse voltage of 200V. It supports an average forward current of 6A and withstands a surge peak forward current of 175A under standard conditions. The device utilizes a GBU-4 through-hole package with matte tin-plated leads, measuring approximately 22.3mm in length, 3.56mm in width, and 18.8mm in height. Electrical characteristics include a maximum forward voltage of 1.1V at 6A and a typical reverse leakage current of 5µA at 25°C. Operating temperatures range from -55°C to +150°C.

Procurement Notes

Verify component authenticity by checking the marking code against official datasheet diagrams. Confirm AEC-Q101 qualification status via the specific ordering suffix if automotive compliance is required. Ensure packaging type matches project needs, as options include tubes or reels. Cross-reference the manufacturer part number with distributor listings to confirm availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a 200V blocking capability is required for AC-to-DC conversion circuits. The 6A continuous current rating suits moderate power applications. Verify thermal management requirements based on the junction-to-ambient thermal resistance value. Ensure the GBU-4 footprint aligns with the printed circuit board layout constraints and mounting torque specifications.

Part Context

This component belongs to the GBU6 series of standard bridge rectifiers manufactured by Taiwan Semiconductor. The series covers voltage ratings from 50V to 1000V, sharing identical mechanical dimensions and current ratings across variants. The GBU603 specifically addresses the 200V segment within this standardized product family.

Replacement Considerations

Direct replacements must match the 6A current rating, 200V reverse voltage, and GBU-4 package outline. Verify that alternative components meet the same thermal resistance and operating temperature specifications.
