MMBZ5226BTS-7-F

Overview

The MMBZ5226BTS-7-F is a triple surface mount Zener diode array manufactured by Diodes Incorporated. It integrates three isolated Zener diodes within an SOT363 package, designed for automated assembly processes. The nominal Zener voltage is 3.3 V, with a range of 3.14 V to 3.47 V at a test current (IZT) of 20 mA. Maximum reverse leakage current is 25 µA at VR = 1.0 V, and maximum Zener impedance (ZZ) is 28 Ω at IZT. Power dissipation is rated at 200 mW, with a thermal resistance (RθJA) of 625 °C/W. Operating and storage temperatures span 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 applications.
• Compliant with RoHS directives and defined as a Halogen and Antimony-free "Green" device.

Applications

• Automated assembly processes requiring compact multi-channel voltage regulation.
• High reliability electronic circuits necessitating qualified components.
• Space-constrained printed circuit board layouts utilizing the SOT363 form factor.

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the ordering suffix matches the specific electrical characteristics required for the design. Ensure compliance with environmental regulations relevant to the target market. Check for any recent product change notices regarding material or packaging updates.

Selection Notes

Select this component when multiple independent voltage references are needed in a minimal footprint. Verify that the 200 mW power dissipation rating accommodates the thermal environment. Ensure the 3.3 V nominal voltage aligns with the circuit requirements. Consider the SOT363 package dimensions against available PCB space constraints.

Part Context

This part belongs to the MMBZ5221BTS through MMBZ5259BTS series of triple Zener arrays. All devices in this family share the same SOT363 physical package and mechanical data but differ in Zener voltage ratings. The series provides a standardized solution for multi-voltage reference needs across various Diodes Incorporated product lines.

Replacement Considerations

Substitute parts must maintain the SOT363 package and triple Zener configuration. Verify equivalent Zener voltage, power dissipation, and impedance specifications. Ensure compatibility with existing PCB footprints and automated placement equipment. Confirm that alternative sources meet the same AEC-Q101 qualification standards if required.
