Overview
The MMBZ5229BTS-7-F is a triple surface mount Zener diode array manufactured by Diodes Incorporated. It integrates three isolated Zener diodes within an SOT363 package, designed for automated assembly processes. The nominal Zener voltage is 4.3 V, with a range of 4.09 V to 4.52 V at a test current (IZT) of 20 mA. Maximum reverse leakage current is 5.0 µA at VR = 1.0 V. The device has a power dissipation rating of 200 mW and operates within a temperature range of -65°C to +150°C.
Feature Summary
- Integrates three electrically isolated Zener diodes in a single ultra-small surface mount package.
- Qualified to AEC-Q101 standards for high reliability applications.
- Manufactured using totally lead-free materials that are fully RoHS compliant.
- Constructed as a halogen and antimony free "Green" device.
Applications
- Automated assembly processes requiring compact multi-channel voltage regulation.
- General purpose medium current circuit protection.
- High reliability electronic systems meeting automotive qualification standards.
Procurement Notes
Verify the specific ordering suffix matches the required packaging configuration. Confirm compliance requirements such as RoHS and Halogen-free status against project specifications. Ensure the component marking code aligns with the intended voltage variant during incoming inspection.
Selection Notes
Select this component when multiple independent voltage references are needed in a restricted footprint. Evaluate the total capacitance and impedance characteristics relative to the target frequency response. Verify thermal resistance limits under expected operating conditions on the specific PCB layout.
Part Context
This part belongs to the MMBZ5221BTS through MMBZ5259BTS series of triple Zener arrays. The series offers various nominal voltages from 2.4 V to 39 V, all sharing the same SOT363 mechanical outline and electrical testing methodology defined in datasheet DS30184.
Replacement Considerations
Direct substitutes include other MMBZ5229BTS variants from Diodes Incorporated with identical pinouts and electrical ratings. Cross-manufacturer replacements must match the SOT363 package dimensions and the 4.3 V triple Zener configuration.
