Overview
The MMBZ5223BS-7 is a dual isolated Zener diode array manufactured by Diodes Incorporated in an SOT-363 surface-mount package. It features two independent Zener channels with a nominal breakdown voltage of 2.7V per channel, tested at a current of 0.25mA. The device has a maximum power dissipation of 200mW and a maximum Zener impedance of 30Ω at the test current. It operates within a temperature range of -65°C to +150°C and includes a forward voltage of 0.9V at 10mA.
Feature Summary
- Dual isolated Zener configuration housed in an ultra-small surface mount package
- Planar die construction designed for automated assembly processes
- Lead-free plating with matte tin finish annealed over Alloy 42 leadframe
Applications
- Voltage reference circuits requiring dual isolated channels
- Signal clamping applications in compact electronic designs
- Overvoltage protection for low-voltage signal lines
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the component meets RoHS compliance requirements if restricted substances are a constraint for the intended application. Ensure the date code aligns with any green molding compound specifications required by the project.
Selection Notes
Select this component when a dual-channel Zener solution is needed in a minimal footprint. The SOT-363 package allows for space-constrained layouts. Verify that the 2.7V breakdown voltage and 200mW power rating suit the circuit's electrical demands and thermal environment.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series covers various Zener voltages ranging from 2.4V to 39V. All devices share the same physical package and general electrical characteristics, differing primarily in their specific breakdown voltage ratings.
Replacement Considerations
Direct substitutes include other MMBZ5223BS variants from Diodes Incorporated with identical electrical specifications. Cross-manufacturer replacements must match the SOT-363 package dimensions, 2.7V nominal voltage, and dual isolated configuration.
