Overview
The MMBZ5257BTS-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 33V, with a range of 31.35V to 34.65V at a test current of 3.8mA. Maximum Zener impedance is 58 Ohms at IZT and 700 Ohms at ZZK. The device dissipates up to 200mW with a thermal resistance of 625°C/W. Operating temperature ranges from -65°C to +150°C. It features matte tin plating and complies with AEC-Q101 standards.
Feature Summary
- Integrates three electrically isolated Zener diodes in a compact ultra-small surface mount package.
- Qualified to AEC-Q101 automotive reliability standards for high-performance applications.
- Manufactured using lead-free, halogen-free, and antimony-free green materials.
Applications
- Automotive electronic circuits requiring multiple voltage references.
- Portable devices utilizing automated surface mount assembly.
- General purpose voltage regulation and protection in multi-channel systems.
Procurement Notes
Verify the specific ordering suffix matches the required packaging configuration before purchase. Confirm RoHS compliance status aligns with project environmental regulations. Ensure the component marking code corresponds to the intended electrical characteristics. Check for any recent product change notices that may affect specifications or availability.
Selection Notes
Select this component when multiple independent voltage references are needed in a restricted footprint. Verify that the total power dissipation requirements do not exceed the 200mW limit under operating conditions. Consider the thermal resistance value when designing the PCB layout to ensure adequate heat dissipation.
Part Context
This part belongs to the MMBZ5221BTS through MMBZ5259BTS series of triple Zener arrays. All variants share the same SOT363 physical package and pinout but differ in specific Zener voltage ratings. The series provides a standardized solution for space-constrained designs requiring multiple voltage levels.
Replacement Considerations
Direct substitutes include other MMBZ5257BTS variants from Diodes Incorporated with identical electrical parameters. Cross-manufacturer replacements must match the SOT363 package dimensions and the 33V nominal Zener voltage specification precisely.
