MB14S

Bridge Rectifier Overview

The MB14S is a surface mount Schottky bridge rectifier manufactured by Good-Ark Semiconductor, designed for high-efficiency power conversion applications. It features a maximum repetitive peak reverse voltage of 40V and supports an average forward output current of 1A. The device exhibits a maximum instantaneous forward voltage of 0.7V at 1.0A, ensuring low power loss. It offers a peak forward surge current rating of 30A and operates within a junction temperature range of -55°C to 150°C. Encapsulated in the TO-269AA (MBS) package, it provides space-saving integration with terminals solderable per MIL-STD-750 Method 2026.

Bridge Rectifier Feature Summary

• Glass passivated chip junctions integrated into a molded plastic case for enhanced reliability.
• High surge overload capability rated at 30A peak for robust transient handling.
• Designed for automated assembly with high-temperature soldering guarantees up to 260°C.

Bridge Rectifier Applications

• Low voltage rectification circuits
• High efficiency DC-to-DC converters
• Switch mode power supplies

Bridge Rectifier Procurement Notes

Verify the specific part number against the official Good-Ark Semiconductor datasheet to confirm electrical parameters match design requirements. Ensure the procurement source provides documentation confirming compliance with UL flammability classification 94V-0 and RoHS directives. Cross-reference the MBS package dimensions with PCB layout specifications to guarantee proper mechanical fit and thermal performance during implementation.

Bridge Rectifier Selection Notes

Select the MB14S when a 40V reverse voltage rating and 1A continuous current capacity are required in a compact surface mount form factor. Consider this component for designs prioritizing low forward voltage drop to minimize conduction losses. Evaluate the thermal resistance characteristics relative to the available copper pad area on the printed circuit board to ensure adequate heat dissipation under full load conditions.

Bridge Rectifier Part Context

The MB14S belongs to the MB12S through MB110S series of surface mount Schottky bridge rectifiers from Good-Ark Semiconductor. This family shares common mechanical and functional attributes, including the TO-269AA (MBS) package and glass-passivated junction technology. The series differentiates primarily by reverse voltage ratings ranging from 20V to 100V while maintaining a consistent 1A forward current capability across all variants.

Bridge Rectifier Replacement Considerations

Compatible substitutes include the MB14S from Jingdao Microelectronics and the KMB22S from SMC. Verify that alternative sources specify identical 40V reverse voltage, 1A current rating, and MBS package compatibility before substitution.
