Overview
The MMBZ5256BS-7-F is a dual isolated Zener diode manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It features a nominal Zener voltage of 30 V with a tolerance range of 28.50 V to 31.50 V at a test current of 4.2 mA. The device supports a maximum power dissipation of 200 mW and operates within a temperature range of -65°C to +150°C. Key electrical parameters include a maximum Zener impedance of 49 Ω and a reverse leakage current of 0.1 μA at 23 V. The forward voltage is specified as 0.9 V at 10 mA.
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 requiring compact components
- Voltage reference applications utilizing dual independent channels
- General-purpose surface mount circuit protection
Procurement Notes
Verify the specific ordering suffix '-7-F' corresponds to the 3000-unit tape and reel packaging format. Confirm that the component meets lead-free requirements if applicable to your assembly process. Ensure the supplier provides documentation verifying compliance with RoHS standards and UL flammability classification 94V-0 for the molded plastic case material.
Selection Notes
Select this component when dual isolated Zener functionality is required in a minimal footprint. The SOT-363 package is suitable for high-density PCB layouts. Consider the 200 mW power dissipation limit and thermal resistance of 625 °C/W when designing heat management strategies. Verify that the 30 V breakdown voltage aligns with the target circuit requirements.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series offers various Zener voltage options ranging from 2.4 V to 39 V within the same SOT-363 package. The 'KM1' marking code identifies the 30 V variant specifically. The series is designed for general-purpose surface mount applications.
Replacement Considerations
Direct substitutes within the same series include other MMBZ52xxBS variants with different voltage ratings but identical packaging. Cross-manufacturer replacements must match the SOT-363 outline dimensions and electrical characteristics such as Zener voltage tolerance and power dissipation limits.
