Overview
The MMBZ5223BS-7-F is a dual isolated Zener diode array manufactured by Diodes Incorporated in an SOT-363 surface-mount package. It features planar die construction and provides two independent 2.7V Zener channels with a ±5% tolerance range (2.57V to 2.84V). The device operates at a test current of 0.25mA, exhibits a maximum Zener impedance of 30 Ohms, and has a maximum reverse leakage current of 1300µA at 1.0V. Total power dissipation is rated at 200mW, with a forward voltage of 0.9V at 10mA. It supports an operating temperature range from -65°C to +150°C.
Feature Summary
- Dual isolated Zener configuration within an ultra-small surface mount package
- Planar die construction for reliable performance
- Lead-free and RoHS compliant manufacturing
Applications
- Automated assembly processes
- Voltage reference circuits
- Signal clamping applications
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details. Confirm that the component meets required environmental standards such as RoHS compliance and moisture sensitivity levels before procurement. Ensure compatibility with automated assembly equipment specifications.
Selection Notes
Select this component when a dual-channel voltage regulation solution is required in a compact footprint. Consider the 200mW total power dissipation limit and the specific 2.7V breakdown characteristics. Verify thermal resistance requirements relative to the FR4 PCB pad layout for optimal heat dissipation.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series of surface mount Zener diodes. All devices in this family share identical mechanical dimensions and packaging options but vary in nominal Zener voltage and corresponding electrical parameters.
Replacement Considerations
Direct substitutes include other MMBZ5223BS variants from Diodes Incorporated with compatible packaging. Cross-manufacturer replacements must match the SOT-363 outline, 2.7V nominal voltage, and 200mW power rating.
FAQ
What is the marking code for the MMBZ5223BS?
The product type marking code for the MMBZ5223BS is KC3.
How is the power dissipation affected by ambient temperature?
Power dissipation decreases linearly above 25°C according to the derating curve provided in the datasheet, based on mounting on an FR4 PC board.
What is the maximum non-repetitive surge power capability?
The device can withstand peak surge power pulses, with the maximum allowable pulse width dependent on the surge power level as shown in the surge power graph.
