RS403L

Bridge Rectifier Overview

The RS403L is a single-phase bridge rectifier manufactured by Diodes Incorporated, designed for general-purpose power supply applications. It features a maximum average forward rectified output current of 4.0 A at an ambient temperature of 50°C and supports a peak forward surge current of 200 A under JEDEC testing conditions. The component provides a maximum DC blocking voltage of 200 V and a maximum repetitive peak reverse voltage of 200 V. Electrical characteristics include a maximum forward voltage of 1.0 V at 3.0 A and a maximum DC reverse current of 10 mA at 25°C. The device operates within a junction temperature range of -55°C to +150°C and utilizes the RS-4L plastic package.

Bridge Rectifier Feature Summary

• High reliability construction with low leakage current characteristics
• Surge overload rating capable of handling 200 A peak current
• Plastic package meets UL flammability classification 94V-0 standards
• Suitable for oriented circuit board mounting positions

Bridge Rectifier Applications

• General-purpose power supply circuits
• Single-phase half-wave rectification in resistive or inductive loads
• AC to DC conversion modules

Bridge Rectifier Procurement Notes

Verify that the specific part number matches the required voltage rating among the RS401L through RS407L series variants. Confirm compliance with RoHS directives if applicable to the project requirements. Ensure the procurement source provides official datasheets to validate electrical parameters against the manufacturer's specifications before integration into designs.

Bridge Rectifier Selection Notes

Select this component when a 200 V blocking voltage and 4.0 A continuous current capacity are required in a compact axial leaded package. Consider derating the forward current by 20% if used with capacitive loads. Evaluate thermal management strategies as the device dissipates heat based on the forward voltage drop and load current during operation.

Bridge Rectifier Part Context

This component belongs to the RS401L-RS407L series of 4.0 A bridge rectifiers from Diodes Incorporated. The series offers varying voltage ratings from 50 V to 1000 V while maintaining consistent current handling capabilities. The RS403L specifically addresses applications requiring 200 V isolation. The manufacturer notes that this series is not recommended for new designs, suggesting consideration of alternative packages like GBU4005.

Bridge Rectifier Replacement Considerations

The datasheet explicitly recommends using GBU4005 through GBU410 series components instead of this product for new designs. These alternatives likely offer improved packaging or performance characteristics aligned with modern manufacturing standards.
