Overview
The MMBZ5231BTS-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, designed for automated assembly processes. The nominal Zener voltage is 5.1V, with a range of 4.85V to 5.36V at a test current (IZT) of 0.25mA. Maximum Zener impedance is 17Ω at IZT and 1600Ω at IZK. Maximum reverse leakage current is 5.0µA at VR = 2.0V. Power dissipation is 200mW, with a thermal resistance (RθJA) of 625°C/W. Operating temperature ranges 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 automotive applications
- Totally lead-free and fully RoHS compliant with halogen and antimony-free green device construction
Applications
- Automotive electronics requiring high reliability voltage regulation
- Portable devices utilizing automated surface mount assembly processes
- Multi-voltage reference circuits in compact form factors
Procurement Notes
Verify the complete part number includes the -7-F suffix to confirm tape and reel packaging containing 3000 units per reel. Confirm RoHS compliance status matches specific project requirements. Check for any recent product change notices regarding encapsulant or marking updates. Ensure sourcing channels are authorized to avoid counterfeit components.
Selection Notes
Select this component when multiple independent voltage references are needed in a space-constrained design. The SOT-363 package offers a small footprint suitable for dense PCB layouts. Verify that the 5.1V nominal voltage aligns with circuit requirements. Consider the 200mW power dissipation limit and thermal resistance when designing heat management strategies.
Part Context
This part belongs to the MMBZ5221BTS through MMBZ5259BTS series of triple Zener arrays. Each variant provides different Zener voltage combinations while maintaining the same physical package and electrical characteristics structure. The series is designed to replace discrete diode solutions, saving board space and simplifying assembly.
Replacement Considerations
Direct replacements include other MMBZ5231BTS variants with different packaging suffixes such as MMBZ5231BTS-13. Cross-referencing with equivalent triple Zener arrays from other manufacturers requires verifying pinout compatibility and electrical parameter tolerances.
