Overview
The MMBZ5259BTS-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 39V with a tolerance range of 37.05V to 40.95V. The device operates at a test current of 3.2mA and features a maximum Zener impedance of 80 Ohms. Power dissipation is rated at 200mW, with a thermal resistance of 625°C/W. It supports an operating temperature range from -65°C to +150°C and includes a maximum reverse leakage current of 0.1µA.
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.
- Manufactured using lead-free plating with matte tin finish on an Alloy 42 leadframe.
- Designed for automated assembly processes with moisture sensitivity level 1.
Applications
- Voltage regulation in multi-rail power supply systems
- Transient voltage suppression in automotive electronics
- Reference voltage generation in precision measurement circuits
Procurement Notes
Verify the specific ordering suffix matches the required packaging configuration. Confirm compliance with RoHS directives and halogen-free requirements if mandated by project specifications. Ensure the supplier provides traceability documentation consistent with AEC-Q101 qualification standards. Check for date code markings to verify manufacturing recency and storage conditions.
Selection Notes
Select this component when multiple independent voltage references are required in a compact footprint. The SOT-363 package offers space savings compared to discrete components. Evaluate the 200mW power dissipation limit against expected thermal loads. Consider the 80 Ohm impedance value for dynamic regulation requirements in the target circuit design.
Part Context
This part belongs to the MMBZ5221BTS through MMBZ5259BTS series of triple Zener arrays. The series covers a wide voltage range from 2.4V to 39V per diode. All variants share the same SOT-363 mechanical outline and electrical testing conditions, differing primarily in the specific Zener voltage breakdown characteristics defined by their marking codes.
Replacement Considerations
Direct replacements include other MMBZ5259BTS variants from Diodes Incorporated with identical electrical parameters. Verify pinout compatibility and package dimensions when substituting with parts from other manufacturers offering equivalent triple Zener arrays in SOT-363 packages.
FAQ
What is the marking code for the MMBZ5259BTS?
The product type marking code for the MMBZ5259BTS is KRE.
How is the triple Zener array configured internally?
The device contains three isolated Zener diodes within a single SOT-363 package, allowing for independent operation of each channel.
What is the maximum reverse leakage current specified?
