MMSZ5238B-7-F

Single Zener Diodes Overview

The MMSZ5238B-7-F is a single surface-mount Zener diode manufactured by Diodes Incorporated, housed in an SOD123 package. It provides a nominal Zener voltage of 8.7 V with a tolerance range of 8.27 V to 9.14 V at a test current of 20 mA. The device supports a maximum power dissipation of 500 mW at 25°C ambient temperature and operates within a junction temperature range of -65°C to +150°C. Electrical characteristics include a maximum Zener impedance of 8 Ω and a maximum reverse leakage current of 3 µA at 6.5 V.

Single Zener Diodes Feature Summary

• Designed for automated assembly processes with general-purpose medium current capabilities
• Compliant with AEC-Q101 standards for high reliability applications
• Constructed with lead-free, halogen-free, and antimony-free green molding compound

Single Zener Diodes Applications

• Voltage regulation circuits
• Clamping applications
• Protection against overvoltage transients

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to commercial grade qualification and standard 3,000-unit tape and reel packaging. Confirm that the component meets RoHS directives and matches the required SOD123 footprint dimensions for PCB layout compatibility before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 8.7 V reference or clamp is required in space-constrained designs utilizing the SOD123 form factor. Ensure the circuit design accommodates the specified 20 mA test current for accurate voltage regulation and verify thermal management requirements align with the 500 mW power dissipation rating under expected operating conditions.

Single Zener Diodes Part Context

This part belongs to the MMSZ5221B through MMSZ5259B series of 500mW surface mount Zener diodes. The series offers a wide range of voltage options from 2.4V to 39V, all sharing identical mechanical data and packaging specifications. The MMSZ5238B variant specifically targets the 8.7V nominal requirement within this standardized product family.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same manufacturer series include other MMSZ52xxB-7-F variants with different voltage ratings but identical SOD123 packaging and electrical profiles. Cross-manufacturer replacements must match the SOD123 outline dimensions, 500mW power rating, and 8.7V Zener voltage tolerance.
