Overview
The MMBZ5238BS-7 is a dual isolated Zener diode array manufactured by Diodes Incorporated in an SOT-363 surface-mount package. It contains two independent Zener diodes with a nominal breakdown voltage of 8.7V, ranging from 8.27V to 9.14V at a test current of 0.25mA. The device features a maximum power dissipation of 200mW and a thermal resistance of 625°C/W. Electrical specifications include a maximum Zener impedance of 8Ω at 0.25mA and a maximum reverse leakage current of 3.0µA at 6.5V. The forward voltage is rated at 0.9V at 10mA, with an operating temperature range spanning -65°C to +150°C.
Feature Summary
- Dual isolated Zener configuration within an ultra-small surface mount package
- Planar die construction for reliable performance
- Lead-free and RoHS compliant manufacturing
Applications
- Automated assembly processes requiring compact components
- Voltage reference applications utilizing dual channels
- Protection circuits requiring isolated Zener arrays
Procurement Notes
Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm packaging details. The standard shipping quantity for this component type is 3000 units per tape and reel. Ensure that the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity and traceability of the date codes.
Selection Notes
Select this component when a dual-channel voltage regulation solution is required in a minimal footprint. The SOT-363 package offers space efficiency compared to discrete single diodes. Consider the 200mW power dissipation limit and the 8Ω impedance characteristic for circuit stability. Verify that the 8.7V nominal voltage aligns with the specific requirements of the target application design.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series, which provides a comprehensive range of dual Zener voltages from 2.4V to 39V. All devices in this family share the same SOT-363 physical dimensions and electrical testing conditions, allowing for consistent mechanical integration across different voltage requirements within the same product line.
Replacement Considerations
Direct substitutes within the same series include other MMBZ52xxBS variants from Diodes Incorporated, provided the voltage rating matches the application needs. Cross-manufacturer replacements must be verified for identical pinout configurations and thermal characteristics in the SOT-363 package.
