W04

Overview

The EIC Semiconductor W04 is a single-phase silicon bridge rectifier designed for general-purpose power supply applications. It provides a maximum average forward rectified output current of 1.5 A at an ambient temperature of 25 °C and supports a maximum repetitive peak reverse voltage of 400 V. The device features a low forward voltage drop of 1.0 V at 1.0 A and exhibits high surge current capability with a non-repetitive peak forward surge current rating of 50 A under JEDEC testing conditions. Electrical characteristics are specified at 25 °C, including a maximum DC reverse current of 10 μA at rated blocking voltage. The component operates within a junction temperature range of -50 to +150 °C and utilizes a molded plastic case with plated leads suitable for printed circuit board mounting.

Procurement Notes

Verify the specific manufacturer datasheet revision date and electrical parameter tolerances before integration. Confirm that the component meets required environmental standards and lead-free specifications for the target assembly process. Ensure thermal management aligns with the specified derating curves for the intended operating environment.

Selection Notes

Select this component based on the 400 V reverse voltage requirement and 1.5 A continuous current capacity. Evaluate the thermal resistance and derating requirements against the expected case temperature in the final application. Consider the physical dimensions and mounting style compatibility with the printed circuit board layout.

Part Context

The W04 belongs to the W005-W10 series of single-phase silicon bridge rectifiers manufactured by EIC Semiconductor. This series covers voltage ratings from 50 V to 1000 V while maintaining a consistent 1.5 A current rating across all variants. The components share identical mechanical construction and package dimensions, differing primarily in their reverse voltage blocking capabilities.

Replacement Considerations

Cross-reference with other manufacturers offering 1.5 A, 400 V bridge rectifiers in the same package type. Verify pinout compatibility and ensure equivalent electrical parameters such as forward voltage drop and surge current ratings.
