MMBZ5241BTS-7-F

Overview

The MMBZ5241BTS-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 11 V, with a range of 10.45 V to 11.55 V at a test current (IZT) of 20 mA. Maximum Zener impedance (ZZ) is 22 Ω, and maximum reverse leakage current (IR) is 2.0 µA at VR = 8.4 V. Power dissipation is rated at 200 mW, with an operating 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 applications.
• Totally lead-free and fully RoHS compliant, featuring halogen and antimony-free green device construction.

Applications

• Automated assembly processes requiring compact multi-channel voltage regulation.
• High reliability electronic systems adhering to automotive qualification standards.
• Multi-voltage reference circuits utilizing isolated channels within a minimal footprint.

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration. Confirm compliance requirements such as RoHS and halogen-free status against project specifications. Ensure the manufacturer source is authorized to guarantee product authenticity and traceability. Check for any recent datasheet revisions that may affect mechanical or electrical parameters.

Selection Notes

Select this component when multiple isolated voltage references are needed in a space-constrained design. The SOT363 package offers a small footprint suitable for dense PCB layouts. Verify that the 200 mW power dissipation rating meets thermal requirements on the target FR4 PCB layout. Ensure the 11 V nominal voltage aligns with circuit protection or regulation needs.

Part Context

This part belongs to the MMBZ5221BTS through MMBZ5259BTS series of triple surface mount Zener diode arrays. The series provides various Zener voltage options ranging from 2.4 V to 39 V within the same SOT363 package form factor. This allows designers to standardize on a single package type while selecting different voltage combinations for complex circuitry.

Replacement Considerations

Direct replacements within the same family include other MMBZ52xxBTS variants from Diodes Incorporated, provided the Zener voltage and pinout compatibility are verified. Cross-manufacturer equivalents in the SOT363 package with triple Zener configurations should be evaluated for matching electrical characteristics and thermal performance.
