MM5Z4688T1G

Single Zener Diodes Overview

The MM5Z4688T1G is a single Zener voltage regulator diode from onsemi, packaged in a surface-mount SOD-523 (CASE 502) outline. It provides a nominal reverse Zener voltage of 4.7 V with a tolerance range of 4.47 V to 4.94 V at a test current of 50 µA. The device features a steady-state power dissipation rating of 500 mW and low reverse leakage current of 10 µA maximum at 3 V. It operates within a junction temperature range of -55°C to +150°C.

Single Zener Diodes Feature Summary

• Designed for high-density applications with a small SOD-523 package footprint
• Provides voltage regulation protection suitable for space-constrained environments
• Features low reverse current characteristics for efficient operation
• ESD rated Class 3 (> 16 kV) per Human Body Model

Single Zener Diodes Applications

• Cellular phones
• Handheld portable devices
• High density PC boards

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging quantity and reel specifications. Ensure compliance with RoHS standards and lead-free requirements as indicated by the 'G' suffix. Confirm that the component meets AEC-Q101 qualification if automotive or PPAP-capable variants are required for the target application.

Single Zener Diodes Selection Notes

Select this component when a compact surface-mount solution is needed for voltage regulation in limited board space. Consider the 500 mW power rating and the specific 4.7 V nominal breakdown voltage. Evaluate the low leakage current and ESD robustness for sensitive circuit protection needs in consumer electronics.

Single Zener Diodes Part Context

This part belongs to the MM5Z4xxxTxG series of Zener Voltage Regulators. The series offers a wide reverse voltage range from 1.8 V to 43 V in the same SOD-523 package style. It serves as an alternative to leadless packages, designed for optimal automated board assembly while maintaining high reliability and thermal performance.

Single Zener Diodes Replacement Considerations

Substitutes within the MM5Z4xxxTxG series may be considered if the nominal Zener voltage matches the design requirement. Verify that any replacement maintains the same SOD-523 mechanical outline and electrical characteristics such as power dissipation and leakage current limits.
