Overview
The MMBZ5251BTS-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 22V, with a range of 20.90V to 23.10V at a test current (IZT) of 5.6mA. Maximum Zener impedance is 29Ω at IZT and 600Ω at ZZK. Power dissipation is rated at 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, containing no intentionally added lead.
- Halogen and antimony free, classified as a "Green" device.
Applications
- Automotive electronics requiring high-reliability voltage regulation.
- Portable devices utilizing automated surface mount assembly processes.
- Multi-voltage reference circuits in compact PCB layouts.
Procurement Notes
Verify the specific ordering suffix matches the required packaging configuration. Confirm that the component meets all applicable environmental compliance standards relevant to the target market. Ensure the supplier provides valid traceability documentation for the manufacturing date code and lot number to maintain quality assurance protocols during integration.
Selection Notes
Select this component when space constraints require multiple independent voltage references in a minimal footprint. Verify that the total power dissipation requirements across all three channels do not exceed the 200mW limit under worst-case ambient conditions. Check that the Zener voltage tolerance aligns with the circuit's precision requirements.
Part Context
This part belongs to the MMBZ5221BTS through MMBZ5259BTS series of triple Zener arrays. The series offers various nominal voltage combinations within the same SOT363 form factor. The "-7-F" suffix indicates tape and reel packaging with 3000 units per reel.
Replacement Considerations
Direct replacements include other MMBZ5251BTS variants from Diodes Incorporated with identical electrical characteristics. Cross-manufacturer equivalents must match the SOT363 pinout, 22V nominal voltage, and 200mW power rating.
