Procurement Notes
Verify the specific ordering suffix matches the required packaging configuration. Confirm compliance requirements such as RoHS status and halogen-free specifications against project constraints. Ensure the date code aligns with material composition policies regarding green molding compounds if applicable. Cross-reference the marking code KM4 to validate device authenticity upon receipt.
Selection Notes
Select this component when dual independent Zener references are needed in a minimal footprint. The SOT-363 package supports high-density board layouts. Verify that the 39V breakdown voltage fits the circuit design requirements. Consider the 200mW power dissipation limit and thermal resistance when determining heat management needs for the application environment.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series offers various Zener voltages ranging from 2.4V to 39V in the same SOT-363 package. All devices share identical mechanical dimensions and electrical testing conditions, allowing for consistent design practices across different voltage requirements.
Replacement Considerations
Direct substitutes include other MMBZ5259BS variants from Diodes Incorporated. Verify pinout compatibility and electrical parameters before substitution. Alternative packages like SOT-323 require schematic redesign.
