GBS4D

Overview

The GBS4D is a single-phase bridge rectifier manufactured by Diotec Semiconductor, designed for AC-to-DC conversion in standard commercial and industrial applications. It features an average forward current (IFAV) of 4 A at 50°C ambient temperature and offers a repetitive peak reverse voltage (VRRM) of 600 V. The device has a maximum forward voltage (VF) of less than 1.05 V at 2 A and a leakage current (IR) below 5 µA at 25°C. It supports a peak forward surge current (IFSM) of 80 A at 50 Hz and operates within a junction and storage temperature range of -50°C to +150°C.

Feature Summary

• Single inline plastic case construction suitable for through-hole mounting on printed circuit boards
• High surge current capability with defined protective resistance requirements for capacitive loads
• Fully isolated case outline ensuring safety and ease of assembly

Applications

• General purpose AC to DC full wave rectification
• Power supplies for monitors, TVs, and printers
• Switching mode power supply input stages

Procurement Notes

Verify the specific suffix D against official Diotec documentation to confirm the 600 V rating. Ensure that the procurement channel provides the original manufacturer datasheet rather than third-party summaries. Confirm RoHS compliance status directly from the supplier's declaration before finalizing orders.

Selection Notes

Select this component when a 600 V blocking voltage and 4 A continuous current are required. Designers must calculate the necessary series protective resistance based on the load capacitance to prevent exceeding the 80 A surge limit. Verify thermal management requirements if operating above 50°C ambient temperature.

Part Context

This part belongs to the GBS4A through GBS4M series of single-phase bridge rectifiers. The series differentiates components primarily by their repetitive peak reverse voltage ratings, ranging from 50 V to 1000 V, while maintaining identical physical dimensions and current handling capabilities across all variants.

Replacement Considerations

Cross-reference with other manufacturers offering 4 A, 600 V single-phase bridge rectifiers in the GBS package. Verify pinout compatibility and thermal resistance characteristics before substitution.
