Overview
The MMBZ5228BS-7 is a dual isolated Zener diode array manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It provides two independent Zener diodes within a single ultra-small footprint, designed for automated assembly processes. The nominal Zener voltage is 3.9V with a tolerance of ±5%, operating at a test current of 20mA. Maximum power dissipation is rated at 200mW, and the device supports an operating temperature range from -65°C to +150°C. Key electrical parameters include a maximum reverse leakage current of 10µA at 1.0V and a maximum Zener impedance of 23Ω.
Feature Summary
- Dual isolated Zener diodes integrated into a compact SOT-363 surface-mount package
- Planar die construction optimized for automated assembly processes
- Lead-free plating with matte tin finish annealed over Alloy 42 leadframe
Applications
- Voltage reference circuits requiring dual independent references
- Transient voltage suppression in space-constrained designs
- Signal clamping applications in portable electronic devices
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and date code markings against the latest datasheet specifications. Ensure storage conditions adhere to moisture sensitivity level 1 requirements to prevent package damage during soldering.
Selection Notes
Select this component when dual independent Zener regulation is required in minimal board space. Compare total capacitance and impedance characteristics against circuit requirements. Verify that the 200mW power dissipation rating accommodates expected thermal loads under maximum ambient temperature conditions.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series, which offers various Zener voltage options in the same SOT-363 package. The series utilizes consistent mechanical dimensions and mounting footprints, allowing for design flexibility while maintaining standardized PCB layouts across different voltage requirements.
Replacement Considerations
Direct substitutes include other MMBZ5228BS variants such as MMBZ5228BS-7-F, which maintains identical electrical characteristics and packaging. Cross-referencing with equivalent dual Zener arrays requires verifying pinout compatibility and ensuring matching voltage tolerance and impedance specifications.
