Overview
The MMBZ5254BS-7-F is a dual isolated Zener diode array manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It features a nominal Zener voltage of 27 V with a tolerance range of 25.65 V to 28.35 V at a test current of 5.0 mA. The device has a maximum power dissipation of 200 mW and a thermal resistance of 625 °C/W. Electrical characteristics include a maximum Zener impedance of 41 Ω and a reverse leakage current of 0.1 μA at 21 V. The component operates within a temperature range of -65°C to +150°C.
Feature Summary
- Dual isolated Zener configuration in an ultra-small surface mount package
- Planar die construction for reliable performance
- Lead-free and RoHS compliant manufacturing
Applications
- Voltage reference circuits requiring compact form factors
- Automated assembly processes for high-volume production
- General-purpose voltage regulation in portable electronics
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The standard suffix indicates tape and reel shipping quantities. Confirm compliance requirements such as RoHS status and moisture sensitivity levels prior to integration into final assemblies.
Selection Notes
Select this component when space constraints require a dual Zener solution in an SOT-363 footprint. Ensure the 27 V breakdown voltage aligns with circuit requirements. Consider the 200 mW power dissipation limit and thermal resistance when designing heat management strategies for the application.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series offers various Zener voltages ranging from 2.4 V to 39 V within the same physical package. This allows designers to maintain consistent board layouts while adjusting voltage specifications across different product variants.
Replacement Considerations
Direct replacements must match the SOT-363 package, 27 V nominal voltage, and dual isolated configuration. Verify that alternative manufacturers provide equivalent electrical parameters, specifically Zener impedance and leakage current, to ensure circuit compatibility.
