MMSZ4686-TP

Single Zener Diodes Overview

The MMSZ4686-TP is a single Zener diode from Micro Commercial Components, housed in an SOD-123 surface-mount package. It provides a nominal Zener voltage of 3.9 V with a tolerance of ±5%, ranging from 3.705 V to 4.095 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 5.0 µA at 2.0 V, and a thermal resistance of 340°C/W.

Single Zener Diodes Feature Summary

• Halogen-free construction designated as a 'Green' device
• Moisture sensitivity level 1 for reliable handling
• Epoxy material meets UL 94 V-0 flammability rating

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Single Zener Diodes Procurement Notes

Verify the specific part number suffix against official distributor catalogs to confirm packaging configuration. Ensure compliance with RoHS directives and halogen-free requirements by checking the manufacturer's ordering information. Confirm that the component source is authorized to guarantee traceability and adherence to quality standards.

Single Zener Diodes Selection Notes

Select this component for designs requiring a 3.9 V regulation point in a compact SMD footprint. Evaluate the 500 mW power dissipation limit against expected operating conditions. Consider the low leakage current specification for sensitive analog sections where minimal current draw during non-conduction is critical.

Single Zener Diodes Part Context

This component belongs to the MMSZ4678 through MMSZ4716 series, which covers Zener voltages from 1.8 V to 39 V. All devices in this family share the same SOD-123 package dimensions and general electrical characteristics, differing primarily in their specific breakdown voltage ratings and corresponding marking codes.
