MMBZ5227BS-7-F

Overview

The MMBZ5227BS-7-F is a dual isolated Zener diode manufactured by Diodes Incorporated, housed in an SOT-363 surface mount package. It features a nominal Zener voltage of 3.6 V with a tolerance range of 3.42 V to 3.78 V at a test current of 20 mA. The device has a maximum power dissipation of 200 mW and a thermal resistance of 625 °C/W. Electrical specifications include a maximum Zener impedance of 24 Ω at the test current and a maximum reverse leakage current of 15 μA at 1.0 V. The forward voltage is rated at 0.9 V when tested at 10 mA.

Feature Summary

• Dual isolated Zener configuration within an ultra-small surface mount package
• Planar die construction for reliable performance
• Lead-free plating with matte tin finish over Alloy 42 leadframe

Applications

• Automated assembly processes requiring compact components
• Voltage reference applications utilizing dual independent channels
• Surface mount circuit designs constrained by space limitations

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the ordering suffix -7-F corresponds to the specified tape and reel packaging format containing 3000 units per reel. Ensure compliance with RoHS directives and check date codes for green molding compound requirements if halogen-free status is critical for the application.

Selection Notes

Select this component when a dual Zener solution is required in a minimal footprint. The SOT-363 package accommodates two independent devices, reducing board space compared to single discrete packages. Verify that the 3.6 V breakdown voltage aligns with circuit requirements and that the 200 mW power rating is sufficient for the expected operating conditions without exceeding thermal limits.

Part Context

This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series offers various Zener voltage options ranging from 2.4 V to 39 V within the same SOT-363 package. This standardization allows designers to maintain consistent board layouts while adjusting voltage specifications across different product variants.

Replacement Considerations

Direct substitutes within the same series include other MMBZ52xxBS-7-F variants with different voltage ratings but identical packaging. Cross-referencing electrical parameters such as impedance and leakage current is necessary when substituting with parts from other manufacturers to ensure functional equivalence.
