Overview
The MMBZ5226BS-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 3.3 V with a tolerance range of 3.14 V to 3.47 V at a test current of 20 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 28 Ω, a maximum reverse leakage current of 25 µA at 1.0 V, and a forward voltage of 0.9 V at 10 mA. Operating and storage temperatures range from -65°C to +150°C.
Feature Summary
- Dual isolated Zeners integrated into an ultra-small surface mount package
- Planar die construction for reliable performance
- Lead-free plating with matte tin finish annealed over Alloy 42 leadframe
Applications
- Automated assembly processes
- Voltage reference circuits
- Signal clamping applications
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The standard configuration utilizes tape and reel shipping. Confirm RoHS compliance status and date code requirements prior to procurement to ensure alignment with project specifications and environmental regulations.
Selection Notes
Select this component when dual independent Zener regulation is required within a compact footprint. Ensure the circuit design accommodates the specified 200 mW power dissipation limit and the 625 °C/W thermal resistance. Verify that the 3.3 V breakdown voltage aligns with the target application's voltage requirements.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series, which provides various Zener voltage options in the same SOT-363 package. The series is designed for general-purpose surface mount applications requiring small form factors and automated handling capabilities.
Replacement Considerations
Direct substitutes include other manufacturers' dual Zener arrays in SOT-363 packages with matching 3.3 V ratings and electrical characteristics. Verify pinout compatibility and thermal performance before substitution.
