MMSZ5235B-7

Single Zener Diodes Overview

The MMSZ5235B-7 is a surface mount Zener diode from Diodes Incorporated, housed in an SOD123 package. It provides a nominal Zener voltage of 6.8V with a tolerance range of 6.46V to 7.14V at a test current of 20mA. The device supports a maximum power dissipation of 500mW at a lead temperature of +75°C and 370mW at an ambient temperature of +25°C. Key electrical parameters include a maximum Zener impedance of 5Ω at the test current and a maximum reverse leakage current of 3.0µA at 5.0V. The component operates within a temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

• Designed for automated assembly processes with a compact SOD123 case.
• Totally lead-free and fully RoHS compliant without purposely added lead.
• Constructed as a halogen and antimony free "Green" device.
• Qualified to AEC-Q101 standards for high reliability applications.

Single Zener Diodes Applications

• General purpose voltage regulation circuits
• Medium current clamping applications
• Automotive electronics requiring high reliability

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging quantity and automotive qualification status. The base part number indicates commercial grade availability in tape and reel formats. Confirm compliance requirements such as RoHS and halogen-free status directly with the manufacturer's latest datasheet revisions before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 6.8V reference or clamp is required in a surface mount design. Ensure the circuit current does not exceed the 20mA test current threshold to maintain voltage accuracy. Verify that the thermal environment allows for adequate power derating if operating near the maximum junction temperature limits.

Single Zener Diodes Part Context

This component belongs to the MMSZ5221B through MMSZ5259B series of 500mW surface mount Zener diodes. The series offers a wide range of nominal voltages from 2.4V to 39V within the same SOD123 footprint. This standardization facilitates inventory management and board layout consistency across different voltage requirements in electronic designs.

Single Zener Diodes Replacement Considerations

Direct substitutes include other MMSZ5235B variants from Diodes Incorporated with different packaging suffixes such as -13-F for 10,000-unit reels. Cross-manufacturer replacements must match the 6.8V nominal voltage, 500mW power rating, and SOD123 mechanical dimensions to ensure compatibility.
