Overview
The MMBZ5248BS-7-F is a dual isolated Zener diode manufactured by Diodes Incorporated in an SOT-363 surface mount package. It features a nominal Zener voltage of 18 V with a tolerance range of 17.10 V to 18.90 V at a test current of 7.0 mA. The device has a maximum power dissipation of 200 mW and a thermal resistance of 625 °C/W. Electrical specifications include a maximum Zener impedance of 21 Ω and a maximum reverse leakage current of 0.1 μA at 14 V. The component 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 reliable performance
- Lead-free and RoHS compliant manufacturing
Applications
- Voltage regulation circuits requiring compact dual-channel solutions
- Automated assembly processes utilizing surface mount technology
- General purpose electronic equipment design
Procurement Notes
Verify the specific ordering suffix matches the required packaging format, as the standard designation includes tape and reel quantities. Confirm compliance requirements such as lead-free status against project specifications. Ensure the date code aligns with material composition policies regarding halogen content if applicable to the application environment.
Selection Notes
Select this component when space constraints necessitate a dual Zener solution within an SOT-363 footprint. Compare the 200 mW power dissipation limit against circuit load requirements. Verify that the 18 V breakdown voltage and associated impedance characteristics meet the specific signal conditioning or protection needs of the design.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series provides various Zener voltage options within the same physical package form factor. This allows designers to maintain consistent board layouts while adjusting voltage parameters across different product variants.
Replacement Considerations
Direct replacements must match the SOT-363 package and dual isolated configuration. Verify equivalent electrical parameters including the 18 V nominal voltage, 200 mW power rating, and similar impedance values to ensure functional compatibility.
