GBU403 D2G

Overview

The GBU403 D2G is a single-phase standard bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a 4 A average rectified current and a maximum repetitive peak reverse voltage of 200 V. The device utilizes a glass-passivated silicon junction for enhanced reliability. Electrical characteristics include a forward voltage drop of 1.1 V at 4 A and a maximum reverse leakage current of 5 µA at 200 V. It operates within a junction temperature range of -55°C to +150°C and is housed in an isolated GBU package designed for through-hole mounting.

Feature Summary

• Glass-passivated junction technology ensures high reliability and resistance to thermal cycling.
• High surge overload capability rated at 150 amperes peak for robust transient protection.
• Molded plastic case constructed with Underwriters Laboratory flammability classification 94V-0.
• Terminals are pure tin-plated, lead-free, and solderable per MIL-STD-202 Method 208.

Applications

• Printed circuit board power supply circuits
• General-purpose AC to DC conversion
• Battery charging systems

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm compliance with RoHS directives and halogen-free status. Confirm the component's active lifecycle status directly with Taiwan Semiconductor Corporation prior to procurement planning. Ensure that the GBU package dimensions align with the target PCB footprint requirements.

Selection Notes

Select this component when a 200 V blocking voltage is required for single-phase rectification applications. The GBU403 D2G is suitable for designs needing a 4 A continuous current rating with through-hole assembly constraints. Evaluate thermal management strategies to maintain junction temperatures within the specified operating range during peak load conditions.

Part Context
