Overview
The MMBZ5230BS-7 is a dual isolated Zener diode array manufactured by Diodes Incorporated. It features two independent Zener diodes housed in an SOT-363 surface-mount package. The nominal Zener voltage is 4.7 V, with a tolerance range of 4.47 V to 4.94 V at a test current of 20 mA. Maximum power dissipation is 200 mW, and the maximum reverse leakage current is 5 µA at 2.0 V. The device 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 reliability
- Lead-free and RoHS compliant manufacturing
Applications
- Automated assembly processes
- Voltage regulation circuits requiring dual references
- Signal clamping applications
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The datasheet indicates that the -7-F suffix corresponds to tape and reel shipping quantities of 3000 units. Confirm compliance requirements such as RoHS status and green material definitions prior to procurement.
Selection Notes
Select this component when space-constrained designs require two independent voltage references. Ensure the circuit design accommodates the 200 mW total power dissipation limit and the specified thermal resistance. Verify that the 4.7 V nominal voltage aligns with the target application requirements.
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 footprint, allowing for design flexibility while maintaining consistent mechanical and thermal characteristics across different voltage ratings.
Replacement Considerations
Direct substitutes include other MMBZ5230BS variants with compatible suffixes, such as MMBZ5230BS-7-F, which share identical electrical specifications and packaging.
