MMBZ5239BTS-7-F

Overview

The MMBZ5239BTS-7-F is a triple surface mount Zener diode array manufactured by Diodes Incorporated. It integrates three isolated Zener diodes within an SOT-363 package, providing a nominal voltage of 9.1 V with a tolerance range of 8.65 V to 9.56 V. The device operates at a test current of 20 mA and features a maximum reverse leakage current of 3.0 µA at 7.0 V. Electrical characteristics include a maximum Zener impedance of 10 Ω at the test current and 600 Ω at a lower current of 0.25 mA. The component supports a power dissipation of 200 mW and functions across a temperature range from -65 °C to +150 °C.

Feature Summary

• Integrates three electrically isolated Zener diodes in a single ultra-small surface mount package
• Qualified to AEC-Q101 standards for high reliability automotive applications
• Totally lead-free and fully RoHS compliant with halogen and antimony free construction

Applications

• Automotive electronic circuits requiring high reliability voltage regulation
• Automated assembly processes utilizing surface mount technology
• Multi-channel voltage reference or protection systems in compact designs

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration before procurement. Confirm that the component meets all applicable environmental compliance standards relevant to the target market. Ensure that the storage and handling procedures adhere to moisture sensitivity level requirements specified in the datasheet to prevent package damage during soldering.

Selection Notes

Select this component when multiple independent voltage references are needed in a space-constrained layout. The SOT-363 package allows for significant board area reduction compared to individual discrete diodes. Verify that the total power dissipation capabilities align with the thermal design of the printed circuit board to maintain junction temperatures within safe operating limits.

Part Context

This part belongs to the MMBZ5221BTS through MMBZ5259BTS series of triple Zener arrays. The series offers various voltage combinations to suit different circuit requirements while maintaining a consistent physical footprint. The standardized pinout and marking codes facilitate inventory management and automated placement in manufacturing environments.

Replacement Considerations

Direct replacements must match the SOT-363 package and contain three isolated Zener diodes. Verify that substitute parts provide equivalent electrical parameters, specifically the 9.1 V nominal voltage and 200 mW power rating. Ensure any alternative components meet the same AEC-Q101 qualification standards if used in automotive applications.
