MSB12M-13

Bridge Rectifier Overview

The MSB12M-13 is a surface mount glass passivated bridge rectifier manufactured by Diodes Incorporated. It features a peak repetitive reverse voltage of 1,000 V and an average rectified output current of 1.2 A at a case temperature of +120°C. The forward voltage ranges from 0.9 V to 1.2 V depending on the current level, with a maximum leakage current of 500 µA at +125°C. The device operates within a temperature range of -55°C to +150°C and supports a non-repetitive peak forward surge current of 45 A. It utilizes an MSB package.

Bridge Rectifier Procurement Notes

This component is officially marked as obsolete and discontinued by the manufacturer. Verification of availability should focus on distributor stock or secondary market sources rather than direct factory orders. Confirm the specific revision status and date codes when sourcing from third-party suppliers to ensure compatibility with existing designs.

Bridge Rectifier Selection Notes

Engineers replacing this part must consider its discontinued status. The datasheet explicitly recommends using the ABS10B as a substitute. Selection criteria should match the original requirements: 1 kV reverse voltage, 1.2 A current rating, and the MSB surface mount package. Verify that any alternative component meets the same thermal resistance and operating temperature specifications.

Bridge Rectifier Part Context

The MSB12M-13 belongs to Diodes Incorporated's line of surface mount bridge rectifiers. It is designed for general-purpose rectification in compact electronic devices. The product falls under the category of single-phase bridge rectifiers intended for high-voltage, low-current applications where space-saving surface mount technology is required.

Bridge Rectifier Replacement Considerations

The official datasheet identifies the ABS10B as the recommended replacement part for the MSB12M.

Bridge Rectifier FAQ

What is the maximum operating junction temperature for the MSB12M?

The maximum operating and storage temperature range for the MSB12M is -55°C to +150°C.

How does the forward current change with case temperature?

The average rectified output current is rated at 1.2 A at a case temperature of +120°C. Derating curves are provided in the datasheet to determine safe operation at higher temperatures.
