MB1505W

Bridge Rectifier Overview

The MB1505W is a single-phase silicon bridge rectifier manufactured by Diodes Incorporated. It features a maximum average rectified output current of 15.0 A at a case temperature of 55°C and a maximum recurrent peak reverse voltage of 50 V. The device has a maximum instantaneous forward voltage drop of 1.1 V at a rated load of 7.5 A. It supports a peak forward surge current of 300 A for a half-sine wave superimposed on a rated load. The component operates within a temperature range of -55°C to +150°C and utilizes wire leads with an MB-W package.

Bridge Rectifier Feature Summary

• High conductivity silicon construction
• Metal case design for superior thermal performance
• Terminals solderable per MIL-STD-202, Method 208
• Universal terminals supporting snap-on, solder, or P.C. board mounting

Bridge Rectifier Applications

• General-purpose AC to DC power supply rectification
• Industrial equipment requiring high current handling
• Automotive electronics applications

Bridge Rectifier Procurement Notes

Verify the specific suffix W indicates wire leads as documented in the mechanical data section. Confirm RoHS compliance status based on the manufacturing date code, noting that lead-free finish applies to date codes 0514 and later. Check for any applicable glass and high-temperature solder exemptions referenced in the EC Directive documentation.

Bridge Rectifier Selection Notes

Select this component for circuits requiring a 15 A continuous current rating and 50 V reverse blocking capability. Ensure the application allows for bolt-down mounting on a heat sink using silicone thermal compound to achieve maximum heat transfer efficiency. Verify that the operating ambient temperature remains within the specified limits for the desired current derating curve.

Bridge Rectifier Part Context

This part belongs to the MB15(W)/25(W)/35(W) series of high current silicon bridge rectifiers. The datasheet explicitly states that this product is not recommended for new designs and suggests using the GBPC15, GBPC25, or GBPC35 series instead. The 'W' suffix specifically denotes the inclusion of wire leads compared to other package variations.

Bridge Rectifier Replacement Considerations

The datasheet recommends the GBPC15 series as a direct replacement for new designs. Other potential substitutes include components from the GBPC25 or GBPC35 series, provided they meet the electrical requirements.
