Overview
The MMBZ5254BS-7-F is a dual isolated Zener diode array manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It features a nominal Zener voltage of 27 V with a tolerance range of 25.65 V to 28.35 V at a test current of 5.0 mA. The device has a maximum power dissipation of 200 mW and a maximum reverse leakage current of 100 nA at 21 V. Electrical characteristics include a maximum Zener impedance of 41 Ω at the test current and 600 Ω at a lower current. The component operates within a temperature range of -65°C to +150°C.
Feature Summary
- Dual isolated Zener configuration in 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 channels
- Automated assembly processes utilizing surface mount technology
- General purpose voltage regulation in compact electronic designs
Procurement Notes
Verify the specific ordering suffix matches the required packaging format. Confirm that the date code aligns with material specifications if halogen-free status is critical for the application. Ensure the supplier provides documentation confirming compliance with the relevant environmental directives stated in the datasheet.
Selection Notes
Select this component when a dual-channel voltage reference is needed in a space-constrained design. Compare the 200 mW power dissipation limit against the expected thermal load. Verify that the 27 V breakdown voltage fits the circuit requirements and check the impedance values for noise sensitivity considerations.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. These devices share the same SOT-363 package and mechanical dimensions but vary in Zener voltage ratings. The series is designed for high-volume automated assembly and offers consistent electrical characteristics across different voltage options.
Replacement Considerations
Direct substitutes must match the SOT-363 package and dual isolated configuration. Verify equivalent Zener voltage (27 V) and power dissipation (200 mW). Check manufacturer-specific parameters such as impedance and leakage current to ensure circuit compatibility.
