Overview
The MMBZ5251BS-7-F is a dual isolated Zener diode manufactured by Diodes Incorporated, designed for surface mount applications. It features planar die construction within an SOT-363 package. The nominal Zener voltage is 22 V with a tolerance range of 20.90 V to 23.10 V at a test current of 5.6 mA. Maximum reverse leakage current is 0.1 µA at 17 V. The device supports a power dissipation of 200 mW and operates within a temperature range of -65 °C to +150 °C.
Feature Summary
- Dual isolated Zener configuration in 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 documentation to confirm packaging details. Confirm that the component meets required environmental standards such as RoHS compliance before integration into final designs. Ensure compatibility with automated pick-and-place equipment due to the small form factor.
Selection Notes
Select this component when space constraints require a dual Zener solution in a compact SOT-363 footprint. Consider the 200 mW power dissipation limit and thermal resistance characteristics for circuit design. Verify that the 22 V breakdown voltage aligns with system requirements and that the low leakage current meets noise sensitivity specifications.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. These devices share common mechanical and electrical characteristics, differing primarily in their specific Zener voltage ratings. The series is optimized for high-volume surface mount production environments.
Replacement Considerations
Direct replacements must match the SOT-363 package and dual isolated configuration. Verify equivalent Zener voltage, power dissipation, and leakage current specifications. Cross-reference with other manufacturers offering similar dual Zener arrays in identical footprints.
