Overview
The MMBZ5256BS-7-F is a dual isolated Zener diode manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It features a nominal Zener voltage of 30 V with a tolerance range of 28.50 V to 31.50 V at a test current of 4.2 mA. The device has a maximum power dissipation of 200 mW and operates within a temperature range of -65°C to +150°C. Key electrical parameters include a maximum reverse leakage current of 0.1 µA at 23 V and a maximum Zener impedance of 49 Ω at the test current.
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 dual independent references
- Clamping applications in signal processing paths
- Protection circuits in compact electronic assemblies
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. Ensure the component meets environmental compliance requirements such as RoHS standards before integration into final products. Cross-reference the date code marking for manufacturing timeline verification.
Selection Notes
Select this component when dual isolated Zener functionality is required in a minimal footprint. Consider the 200 mW power dissipation limit and thermal resistance characteristics for circuit design. Verify that the 30 V breakdown voltage aligns with the target application's voltage regulation needs.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series offers various Zener voltage options within the same SOT-363 package format, allowing for design flexibility while maintaining consistent mechanical and thermal properties across different voltage ratings.
Replacement Considerations
Direct replacements must match the SOT-363 package, 30 V nominal voltage, and dual isolated configuration. Verify equivalent electrical parameters including impedance and leakage current. Check for compatibility with existing PCB pad layouts and soldering profiles.
