MMBD3004SE RFG

Overview

The MMBD3004SERFG is a rectifier diode manufactured by Taiwan Semiconductor Corporation. It features two series-connected silicon elements within a single GREEN plastic package-3 (SOT-26) housing. The device supports a maximum average output current of 0.225 A and a maximum repetitive peak reverse voltage of 350 V. Key electrical characteristics include a maximum power dissipation of 0.35 W, a maximum reverse recovery time of 0.05 µs, and an operating temperature range from -65 °C to 150 °C. The component is RoHS compliant and utilizes a matte tin finish over a copper leadframe.

Feature Summary

• Integrates two series-connected diode circuits into a compact surface-mount package
• Provides high reverse breakdown voltage rating for robust protection
• Features fast switching speed with low reverse recovery time
• Constructed with green molded plastic compound that is halogen and antimony free

Applications

• High voltage surface mount switching applications
• General purpose rectification in consumer electronics
• Signal processing circuits requiring fast switching

Procurement Notes

Verify the specific suffix SERFG against the manufacturer's official datasheet to confirm pinout configuration and material composition. Ensure the ordering part number matches the exact package style and termination finish required for your assembly process. Cross-reference the RoHS compliance status and moisture sensitivity level with current production data sheets to avoid discrepancies during procurement.

Selection Notes

Select this component when a dual-diode configuration is needed in a small outline package. The 350 V rating suits applications requiring higher reverse voltage than standard low-voltage signal diodes. Consider the 0.225 A current limit and 0.35 W power dissipation for thermal management. The SOT-26 footprint allows for space-constrained designs while maintaining high reliability through its plastic epoxy construction.

Part Context

This device belongs to the MMBD3004 family of high voltage surface mount switching diode arrays. It is designed as a compact alternative to discrete diode setups, offering integrated functionality in a three-terminal small outline package. The series connection of internal elements enables full-wave bridge configurations or other multi-diode topologies within a minimal board area.

Replacement Considerations

Cross-reference with MMBD3004BRM-7-F for similar specifications. Verify pin compatibility and electrical ratings before substitution.
