W02G

Overview

The W02G is a single-phase bridge rectifier manufactured by onsemi, designed for general-purpose power supply applications. It features a standard through-hole WOB (Window Overmolded Body) package, providing robust mechanical stability and thermal dissipation capabilities. The device is rated for a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 1.5 A at a case temperature of 84°C. It utilizes silicon planar technology with metal-silicon Schottky barrier construction to ensure high reliability and low leakage current. The component supports a surge current rating of 35 A and operates within a junction temperature range of -55°C to 150°C, making it suitable for various AC-to-DC conversion tasks in consumer and industrial electronics.

Procurement Notes

Verify the specific datasheet revision and ordering suffixes when sourcing, as packaging variations may exist. Confirm that the supplier provides traceable documentation from onsemi authorized channels. Ensure the received components match the WOB package dimensions and pinout specifications required for your PCB layout. Check for any environmental compliance certifications relevant to your manufacturing region before bulk procurement.

Selection Notes

Select the W02G when a 200 V reverse voltage rating and 1.5 A continuous current capacity are sufficient for the load requirements. Consider this component for designs requiring through-hole mounting due to its WOB package form factor. Evaluate the thermal resistance characteristics if the application involves high ambient temperatures or limited airflow. Compare against higher voltage or current variants if system margins require increased headroom beyond the specified 200 V and 1.5 A limits.

Part Context

The W02G belongs to onsemi's portfolio of discrete power diodes and bridge rectifiers, categorized under general-purpose rectification solutions. It complements other devices in the series offering different voltage and current ratings for diverse power management needs. This component is part of the broader market segment for silicon-based rectifiers used in converting alternating current to direct current for electronic circuitry.

Replacement Considerations

Cross-reference with equivalent bridge rectifiers from other manufacturers that specify 200 V reverse voltage and 1.5 A forward current in a compatible WOB package. Verify pin compatibility and thermal performance metrics to ensure seamless integration without redesigning the printed circuit board or altering the cooling infrastructure.
