Overview
The MMBZ5255BTS-7-F is a triple surface mount Zener diode array manufactured by Diodes Incorporated. It integrates three isolated Zener diodes within an SOT363 plastic package. The specific device provides a nominal Zener voltage of 28V with a tolerance range of 26.60V to 29.40V at a test current of 4.5mA. Each diode exhibits a maximum dynamic impedance of 44Ω and a maximum reverse leakage current of 0.1µA at 21V. The component supports a total power dissipation of 200mW and operates across a temperature range of -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, fully RoHS compliant, and halogen and antimony free
Applications
- Automotive electronic circuits requiring multiple voltage references
- Portable equipment utilizing automated assembly processes
- Voltage regulation and protection in compact PCB layouts
Procurement Notes
Verify the complete part number includes the -7-F suffix to confirm tape and reel packaging containing 3000 units per reel. Confirm compliance requirements such as RoHS and AEC-Q101 qualification match project specifications. Ensure the SOT363 package dimensions align with the designated footprint on the printed circuit board layout.
Selection Notes
Select this component when multiple independent voltage reference points are required within a constrained area. The SOT363 package offers a smaller footprint compared to discrete individual diodes. Verify that the 28V nominal voltage and 200mW total power dissipation meet the thermal and electrical demands of the target circuit design.
Part Context
This part belongs to the MMBZ5221BTS through MMBZ5259BTS series of triple Zener arrays from Diodes Incorporated. The series covers a wide voltage range from 2.4V to 39V. The MMBZ5255BTS variant specifically targets the 28V application segment within this family of surface mount devices.
Replacement Considerations
Direct replacements include other MMBZ5255BTS variants from different manufacturers offering identical SOT363 pinouts and 28V characteristics. Verify that any substitute maintains the same isolation between internal diodes and matches the thermal resistance parameters.
