Overview
The MMBZ5254BTS-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 27 V, with a range of 25.65 V to 28.35 V at a test current (IZT) of 5.0 mA. Maximum Zener impedance is 41 Ohms at IZT and 600 Ohms at ZZK. Maximum reverse leakage current is 0.1 µA at VR = 21 V. Power dissipation is 200 mW, with a thermal resistance (RθJA) of 625 °C/W. Operating and storage temperature ranges from -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 automotive applications.
- Totally lead-free and fully RoHS compliant, halogen and antimony free.
Applications
- Automotive electronics requiring high reliability components.
- General purpose voltage regulation circuits.
- Automated surface mount assembly processes.
Procurement Notes
Verify the specific ordering suffix matches the required packaging configuration. Confirm compliance requirements such as RoHS and AEC-Q101 qualification align with project specifications. Ensure the SOT363 footprint dimensions are compatible with the intended PCB layout before finalizing procurement orders.
Selection Notes
Select this component when multiple independent voltage references are needed in a compact space. The 27 V nominal voltage suits specific regulation needs. Verify that the 200 mW power dissipation rating accommodates the thermal environment. Check the 625 °C/W thermal resistance against system cooling capabilities.
Part Context
This part belongs to the MMBZ5221BTS through MMBZ5259BTS series of triple Zener arrays. All devices in this family share the same SOT363 physical package and electrical characteristics structure, differing only in the specific Zener voltage ratings provided in the datasheet table.
Replacement Considerations
Direct substitutes include other MMBZ5254BTS variants from Diodes Incorporated or equivalent triple Zener arrays from other manufacturers offering identical SOT363 pinouts and 27 V nominal voltage specifications.
