Overview
The MMBZ5238BS-7-F is a dual isolated Zener diode array manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It features planar die construction and provides two independent Zener channels within a compact footprint. The nominal Zener voltage is 8.7V, with a minimum of 8.27V and a maximum of 9.14V at a test current of 20mA. Maximum power dissipation is 200mW, and the device operates within a temperature range of -65°C to +150°C. Electrical specifications include a maximum Zener impedance of 8 Ohms at Izt and a maximum reverse leakage current of 3µA at VR.
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 channels
- Automated assembly processes for compact electronics
- General-purpose voltage regulation in surface-mount designs
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details. Confirm that the component meets required environmental standards such as RoHS compliance and moisture sensitivity levels before integration into production workflows.
Selection Notes
Select this component when dual isolated Zener functionality is required in a minimal board area. Ensure the application voltage does not exceed the specified breakdown characteristics and consider the thermal resistance limits for power dissipation in the final enclosure design.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. These devices share common mechanical and electrical characteristics, differing primarily in their specific Zener voltage ratings and corresponding marking codes within the same SOT-363 package family.
Replacement Considerations
Direct substitutes within the same series include other MMBZxxxxBS variants from Diodes Incorporated, provided the Zener voltage requirements match the circuit design. Verify pinout compatibility and thermal characteristics when considering cross-manufacturer alternatives.
