MMBZ5246BS-7

Overview

The MMBZ5246BS-7 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 16 V with a tolerance range of 15.20 V to 16.80 V at a test current of 7.8 mA. The device supports a maximum power dissipation of 200 mW and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum Zener impedance of 17 Ω and a maximum reverse leakage current of 0.1 μA at 12 V. The component utilizes planar die construction and is available in tape and reel packaging.

Feature Summary

• Dual isolated Zener configuration integrated into an ultra-small surface mount package
• Planar die construction designed for automated assembly processes
• Lead-free plating with matte tin finish annealed over Alloy 42 leadframe

Applications

• Voltage reference circuits requiring dual independent references
• Transient voltage suppression in compact electronic assemblies
• Signal clamping applications in high-density PCB layouts

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details. Confirm that the requested part number matches the exact electrical specifications required for the design. Ensure compliance with RoHS directives and check for any date code restrictions regarding molding compound composition if halogen-free status is critical for the application.

Selection Notes

Select this component when dual isolated Zener functionality 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 200 mW power dissipation rating aligns with the thermal management capabilities of the target circuit environment.

Part Context

This device belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series covers a wide range of Zener voltages from 2.4 V to 39 V, all sharing the same SOT-363 package and mechanical specifications. The MMBZ5246BS specifically provides the 16 V breakdown characteristic within this standardized lineup.

Replacement Considerations

Direct replacements must match the SOT-363 package and 16 V dual Zener specification. Other manufacturers offering equivalent pinouts and electrical parameters should be evaluated for thermal resistance and impedance compatibility.
