Overview
The MMBZ5225BS-7-F is a dual isolated Zener diode array manufactured by Diodes Incorporated. It features planar die construction within an SOT-363 surface mount package. The nominal Zener voltage is 3.0 V, with a tolerance range of 2.85 V to 3.15 V at a test current of 20 mA. Maximum power dissipation is 200 mW, and the maximum reverse leakage current is 50 µA at 1.0 V. The device operates between -65°C and +150°C, has a maximum Zener impedance of 30 Ω at 20 mA, and includes a forward voltage of 0.9 V at 10 mA.
Feature Summary
- Dual isolated Zeners integrated in an ultra-small surface mount package
- Planar die construction for reliable performance
- Lead-free plating with matte tin finish over Alloy 42 leadframe
Applications
- Automated assembly processes
- Voltage regulation circuits
- Protection against transient voltages
Procurement Notes
Verify the component authenticity by checking the marking code KC5 on the SOT-363 package. Confirm the datasheet revision DS31039 Rev. 15-2 matches the manufacturer's documentation. Ensure compliance with RoHS standards and verify the moisture sensitivity level (MSL 1) requirements for storage and handling during procurement.
Selection Notes
Select this component when a dual Zener configuration is required in a compact footprint. The 3.0 V nominal voltage suits low-voltage reference applications. Consider the 200 mW power dissipation limit and thermal resistance of 625 °C/W for heat management. Verify that the 50 µA leakage current meets circuit requirements.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. All devices in this family share the same SOT-363 package and 200 mW power rating but vary in Zener voltage and impedance specifications. The series provides multiple voltage options for diverse design needs.
Replacement Considerations
Direct substitutes include other MMBZ5225BS variants from different manufacturers if pin compatibility is maintained. Verify electrical parameters such as Zener voltage tolerance and impedance match before substitution.
