MMSZ4699-TP

Single Zener Diodes Overview

The MMSZ4699-TP is a single Zener diode manufactured by Micro Commercial Components (MCC) in the SOD-123 surface-mount package. It provides a nominal Zener voltage of 12 V with a tolerance of ±5%, ranging from 11.40 V to 12.6 V. The device supports a steady-state power dissipation of 500 mW and operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a test current of 50 µA, a maximum reverse leakage current of 0.05 µA at 9.1 V, and a maximum forward voltage of 0.95 V at 10 mA.

Single Zener Diodes Feature Summary

• Halogen-free construction designated as a "Green" device
• Lead-free finish compliant with RoHS standards
• Moisture sensitivity level 1 for reliable handling
• Epoxy material meets UL 94 V-0 flammability rating

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required packaging format. The standard suffix indicates availability in tape and reel quantities of 3,000 pieces per reel. Confirm compliance requirements such as RoHS status and halogen-free specifications against project documentation before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 12 V reference is required in a compact surface-mount design. Ensure the circuit design accommodates the 500 mW power dissipation limit and the specified thermal resistance of 340°C/W. Verify that the operating environment remains within the -55°C to +150°C junction temperature range for optimal performance.

Single Zener Diodes Part Context

This part belongs to the MMSZ4678 through MMSZ4716 series, which covers Zener voltages from 1.8 V to 39 V. All devices in this series share the same SOD-123 footprint and 500 mW power rating, allowing for standardized board layouts across different voltage requirements within the same product family.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same MCC series include MMSZ4698-TP and MMSZ4700-TP. These alternatives offer adjacent voltage ratings while maintaining identical package dimensions and electrical characteristics.
