Overview
The MMBZ5252BS-7-F is a dual isolated Zener diode array manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It provides two independent Zener channels with a nominal breakdown voltage of 24V and a tolerance of ±5%. The device operates within a power dissipation limit of 200mW at 25°C ambient temperature and features a maximum reverse leakage current of 100nA at 18V. Electrical characteristics include a test current of 5.2mA, a maximum Zener impedance of 33Ω at the test current, and a forward voltage of 0.9V at 10mA. The component supports an operating and storage temperature range from -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 dual independent references
- Automated assembly processes due to surface mount design
- General purpose voltage regulation in compact electronics
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The base part number indicates the electrical specifications, while suffixes define the tape and reel quantity. Confirm compliance requirements such as RoHS status and green material declarations directly from the manufacturer's datasheet before procurement.
Selection Notes
Select this component when dual isolated Zener regulation is required in a minimal footprint. Ensure the circuit design accommodates the 200mW total power dissipation limit and the specific 24V breakdown voltage. Verify that the SOT-363 package dimensions align with the PCB layout constraints and that the thermal resistance allows for adequate heat dissipation under operating conditions.
Part Context
This component belongs to the MMBZ5221BS through MMBZ5259BS series of 200mW surface mount Zener diodes. The series offers a wide range of voltage options from 2.4V to 39V in the same SOT-363 package, allowing for standardized inventory management across different voltage requirements in electronic designs.
Replacement Considerations
Direct replacements within the same series include other MMBZ52xxBS variants with matching voltage ratings. Cross-referencing with equivalent dual Zener arrays in the SOT-363 package from other manufacturers requires verifying pinout compatibility and ensuring identical electrical parameters such as impedance and leakage current.
