MMBZ5248BS-7

Overview

The MMBZ5248BS-7-F is a dual isolated Zener diode array manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It features a nominal Zener voltage of 18 V with a tolerance range of 17.10 V to 18.90 V at a test current of 7.0 mA. The device supports a maximum power dissipation of 200 mW and exhibits a Zener impedance of 21 Ω. Electrical characteristics include a maximum reverse leakage current of 0.1 μA at 14 V and a forward voltage of 0.9 V at 10 mA. Operating temperatures range from -65°C to +150°C.

Feature Summary

• Dual isolated Zener configuration within an ultra-small surface mount package
• Planar die construction for general-purpose applications
• Ideally suited for automated assembly processes

Applications

• Voltage regulation circuits
• General purpose electronic assemblies
• Automated manufacturing environments

Procurement Notes

Verify the complete part number including suffixes such as -7-F against official manufacturer documentation to ensure correct packaging and compliance specifications. Confirm RoHS status and green compound availability based on date codes prior to procurement.

Selection Notes

Select this component when dual independent Zener references are required in space-constrained designs. Ensure the 18 V breakdown voltage aligns with circuit requirements and verify thermal management capabilities given the 200 mW dissipation limit in the SOT-363 package.

Part Context

This device belongs to the MMBZ5221BS through MMBZ5259BS series of surface mount Zener diodes. The series offers various voltage options in standardized packages, providing consistent electrical characteristics and mechanical data across different breakdown voltages for design flexibility.

Replacement Considerations

Direct replacements must match the SOT-363 package, 18 V nominal voltage, and dual isolated configuration. Verify that substitute components meet the same 200 mW power dissipation and temperature range specifications.
