Overview
The MMBZ5230BTS-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 4.7 V, with a range of 4.47 V to 4.94 V at a test current (IZT) of 20 mA. Maximum Zener impedance (ZZ) is 19 Ω, and maximum reverse leakage current (IR) is 5.0 µA at VR = 2.0 V. Power dissipation is rated at 200 mW, 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, fully RoHS compliant, and halogen/antimony free 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 compliance requirements such as RoHS and AEC-Q101 qualification align with project specifications. Ensure the SOT-363 footprint matches the design layout. Check for any recent product change notices that may affect marking or material composition.
Selection Notes
Select this component when multiple independent voltage references are needed in a space-constrained environment. The triple configuration reduces board area compared to discrete components. Verify that the 200 mW power dissipation rating is sufficient for the intended operating conditions and ambient temperature derating curves.
Part Context
This part belongs to the MMBZ5221BTS through MMBZ5259BTS series of triple Zener arrays. It shares the same SOT-363 mechanical outline and electrical testing methodology as other variants in the family, differing primarily in the specific Zener voltage ratings of the internal elements.
Replacement Considerations
Direct replacements include other MMBZ5230BTS variants from Diodes Incorporated with identical electrical characteristics. Cross-manufacturer equivalents must match the SOT-363 package dimensions, 4.7V nominal voltage, and triple isolation configuration.
