Overview
The MMBZ5250BS-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 20 V with a tolerance range of 19.00 V to 21.00 V at a test current of 6.2 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 reverse leakage current of 0.1 µA at 15 V and a maximum Zener impedance of 25 Ω at the test current.
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
- Voltage reference circuits requiring dual independent references
- Clamping applications in signal processing paths
- Protection circuits in compact electronic assemblies
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The standard designation includes the -7-F suffix indicating tape and reel shipping quantities. Confirm compliance requirements such as RoHS status and moisture sensitivity level prior to integration into production workflows.
Selection Notes
Select this component when dual isolated Zener functionality is required in space-constrained designs. Ensure the 200 mW power dissipation rating aligns with the thermal management capabilities of the printed circuit board layout. Verify that the 25 Ω impedance specification meets the dynamic regulation requirements of the target application.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. These devices share the same SOT-363 mechanical footprint and general electrical characteristics, differing primarily in their specific Zener voltage ratings and corresponding marking codes. The series is designed for automated assembly processes.
Replacement Considerations
Direct replacements must match the SOT-363 package and dual isolated configuration. Verify that substitute components maintain equivalent Zener voltage tolerances and power dissipation limits. Cross-reference marking codes if visual inspection is required for quality control.
