MMSZ6V8T1

Single Zener Diodes Overview

The MMSZ6V8T1G is a 500 mW Zener diode in an SOD-123 surface-mount package. It features a nominal reverse Zener voltage of 6.8 V with a ±5% tolerance range of 6.46 V to 7.14 V at IZT = 5 mA. The device exhibits a maximum Zener impedance (ZZT) of 15 Ω and a maximum reverse leakage current of 2 μA at VR = 4 V. It operates within a junction temperature range of -55°C to +150°C and includes ESD protection rated Class 3 (>16 kV) per the Human Body Model.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation within the SOD-123 surface-mount form factor
• Offers high electrostatic discharge robustness exceeding 16 kV via Human Body Model testing
• Designed for automated board assembly processes with void-free thermosetting plastic construction

Single Zener Diodes Applications

• Voltage reference circuits requiring precise low-voltage regulation
• Overvoltage protection stages in signal conditioning paths
• Clamping applications in general-purpose electronic equipment

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix, such as 'G' for lead-free status or 'SZ' for automotive qualification, against project requirements. Confirm that the requested quantity matches the standard tape and reel packaging specifications provided by the manufacturer. Ensure compliance with RoHS directives if applicable to the target market regulations.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V regulation point is required in a compact surface-mount layout. Evaluate the thermal resistance characteristics relative to the PCB copper area available for heat dissipation. Consider the dynamic impedance value for applications demanding minimal voltage variation under changing load currents.

Single Zener Diodes Part Context

This device belongs to the MMSZxxxT1G series of Zener regulators manufactured by onsemi. The series utilizes the SOD-123 case style, designated as CASE 425, which serves as a compact alternative to larger leaded packages. The family covers a wide voltage range from 2.4 V to 56 V, maintaining consistent mechanical and electrical performance standards across variants.

Single Zener Diodes Replacement Considerations

Cross-reference with other MMSZ6V8T1G units from the same series. Verify compatibility with SZMMSZ6V8T1G if automotive site control changes are required. Ensure substitute parts maintain identical SOD-123 footprint and pinout configuration.
