GBP408

Overview

The GBP408 is a standard recovery bridge rectifier manufactured by Diodes Incorporated, rated for a maximum repetitive peak reverse voltage of 800V and a maximum average rectified output current of 4.0A at a case temperature of +90°C. The device features a maximum forward voltage of 1.0V at an IF of 2.0A and a maximum leakage current of 5µA at TJ = +25°C. It utilizes glass passivated die construction within a GBP package, supporting an operating junction temperature range from -55°C to +150°C.

Feature Summary

• Glass passivated die construction ensures reliable operation under various electrical conditions.
• Rated to withstand up to 1000V peak reverse voltage across the product series.
• Designed for efficient printed circuit board mounting using a molded plastic housing.

Applications

• General-purpose AC to DC power supply circuits
• Battery charging systems requiring standard recovery characteristics
• Industrial control equipment utilizing bridge rectification

Procurement Notes

Verify the specific part number against official Diodes Incorporated documentation to confirm the 800V rating and GBP package configuration. Ensure compliance with RoHS 3 and halogen-free requirements as defined in the datasheet notes. Confirm that the ordering suffix matches the required tube packing quantity of 35 units per carrier before finalizing procurement orders.

Selection Notes

Select this component when an 800V blocking capability is required alongside a 4A continuous current rating. Consider the thermal resistance of 7.5°C/W for heatsink calculations if operating near the maximum current limit. Verify that the standard recovery speed meets the frequency requirements of the target application without necessitating ultra-fast or soft-recovery alternatives.

Part Context

This component belongs to the GBP406-GBP410 series of 4A standard recovery bridge rectifiers. The series offers varying reverse voltage ratings (600V, 800V, and 1000V) while maintaining identical current handling and physical package dimensions. This allows designers to standardize on a single footprint for different voltage isolation requirements within a product line.

Replacement Considerations

Direct substitutes include the GBP406 (600V) and GBP410 (1000V) from the same manufacturer, provided the voltage rating aligns with the circuit design. Cross-brand replacements must match the 4A current rating, 800V minimum reverse voltage, GBP package outline, and thermal characteristics to ensure mechanical and electrical compatibility.
