MMBZ5231BS-7-F

Overview

The MMBZ5231BS-7-F is a dual isolated Zener diode array manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It features two independent Zener elements with a nominal breakdown voltage of 5.1V and a tolerance range of 4.85V to 5.36V at a test current of 20mA. The device supports a maximum power dissipation of 200mW per element and operates within a temperature range of -65°C to +150°C. Key electrical parameters include a maximum Zener impedance of 17Ω at 20mA and a maximum reverse leakage current of 5.0µA at 2.0V.

Feature Summary

• Dual isolated Zener configuration within an ultra-small surface mount package
• Planar die construction for high reliability
• Lead-free and RoHS compliant manufacturing

Applications

• Automated assembly processes requiring compact components
• Voltage reference applications utilizing dual independent channels
• General purpose circuit protection and regulation

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the standard tape and reel packaging containing 3000 units per reel. Confirm that the component meets the required environmental standards, specifically checking for compliance with EU Directive 2002/95/EC (RoHS) and ensuring the product date code indicates the use of Green Molding Compound if halogen-free status is mandatory for the application.

Selection Notes

Select this component when a dual-channel voltage reference or protection scheme is required in a space-constrained design. The SOT-363 package offers a compact footprint suitable for high-density PCB layouts. Ensure the 200mW power dissipation rating per element is sufficient for the intended operating conditions and that the 5.1V nominal breakdown voltage aligns with the circuit's voltage requirements.

Part Context

This part belongs to the MMBZ5221BS through MMBZ5259BS series of 200mW surface mount Zener diodes. All devices in this family share the same SOT-363 mechanical case and feature dual isolated Zeners. The specific model MMBZ5231BS is distinguished by its 5.1V nominal breakdown voltage, differentiating it from other voltages in the series such as the 5.6V MMBZ5232BS or 4.7V MMBZ5230BS.

Replacement Considerations

Direct substitutes within the same series include MMBZ5231BS-7-F. Other models in the MMBZ52xxBS family may serve as functional replacements if the voltage rating differs but the package and power dissipation constraints remain identical.
