W10M

Overview

The W10M is a single-phase silicon bridge rectifier manufactured by Taiwan Semiconductor, distributed under the GeneSiC brand. It features four internal elements configured for full-wave rectification with a maximum average forward output current of 1.5 A and a maximum repetitive peak reverse voltage of 1000 V. The device exhibits a maximum non-repetitive peak forward surge current of 50 A and a maximum forward voltage drop of 1 V. It operates at junction temperatures up to 125 °C and utilizes a DOB (Diode Out Box) through-hole package.

Feature Summary

• Surge overload rating capable of handling high transient currents
• Reliable low-cost construction technique suitable for printed circuit boards
• High case dielectric strength for robust performance

Applications

• Printed circuit board power supply designs
• General-purpose AC to DC conversion
• Industrial control systems requiring 1.5 A rectification

Procurement Notes

Verify the manufacturer designation carefully, as the component is produced by Taiwan Semiconductor but often listed under GeneSiC Semiconductor in distribution channels. Confirm the specific suffix or tape-and-reel option if required, though standard units typically come in bulk or tube packaging compatible with the DOB lead frame. Ensure compliance with RoHS standards as indicated in official specifications.

Selection Notes

Select this component when a 1000 V reverse voltage rating is necessary for mains-level applications. The 1.5 A current capacity suits moderate power requirements where thermal management allows for natural convection cooling within the DOB package. Compare against lower voltage variants like W02M if system voltage drops below 200 V, ensuring the selected part meets the peak inverse voltage demands of the specific circuit topology.

Part Context

The W10M belongs to the W005M through W10M series of single-phase silicon bridge rectifiers. This family shares common mechanical data, including molded plastic cases and solder-plated leads, while varying primarily in their voltage ratings from 50 V to 1000 V. The series is designed for cost-effective mass production and reliable operation in standard industrial environments.

Replacement Considerations

Equivalent parts include the W10 from other manufacturers such as Gulf Semiconductor or generic equivalents meeting the 1.5 A / 1000 V / DOB specification. Verify pinout compatibility and thermal resistance characteristics before substitution.
