Overview
The MMBZ5251BS-7-F is a dual isolated Zener diode manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It provides two independent Zener channels with a nominal breakdown voltage of 22V and a tolerance of ±5%. The device dissipates up to 200mW of power at 25°C ambient temperature, with a maximum reverse leakage current of 100µA at 17V. Electrical characteristics include a test current of 5.6mA and a maximum Zener impedance of 29Ω at the test current. The component operates within a temperature range of -65°C to +150°C.
Feature Summary
- Dual isolated Zener channels integrated into a single 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 independent references
- Clamping applications for signal lines
- Protection circuits in compact electronic devices
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm RoHS compliance status and date code requirements for production integration. Ensure the supplier provides valid traceability data matching the manufacturer's specifications before finalizing procurement orders.
Selection Notes
Select this component when dual independent Zener regulation is required in a minimal footprint. Verify that the 200mW power dissipation rating meets the thermal requirements of the target application. Check that the 22V breakdown voltage aligns with the circuit design constraints and that the SOT-363 package fits the available PCB space.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series offers various Zener voltage options within the same SOT-363 package format. This allows designers to maintain consistent board layouts while adjusting voltage specifications across different product variants.
Replacement Considerations
Direct replacements must match the SOT-363 package, 22V nominal voltage, and dual isolated configuration. Verify electrical parameters such as impedance and leakage current against the original datasheet specifications to ensure functional equivalence.
