CMOZ3L9 TR PBFREE

Single Zener Diodes Overview

The CMOZ3L9 TR PBFREE is a low-level silicon Zener diode from the Central Semiconductor CMOZ1L8 series, housed in an SOD-523 ULTRAmini package. It provides a nominal Zener voltage of 3.9 V with a 5% tolerance range (3.71 V to 4.10 V) at a test current of 250 µA. The device features a maximum power dissipation of 250 mW and operates within a junction temperature range of -65°C to +150°C. Electrical specifications include a maximum Zener impedance of 1600 Ω and a maximum reverse leakage current of 5.0 µA.

Single Zener Diodes Feature Summary

• Designed for applications requiring extremely low operating current and low leakage characteristics.
• Utilizes an epoxy-molded ULTRAmini surface mount package for compact circuit integration.
• Functions as a high-quality voltage regulator suitable for precision low-voltage reference needs.

Single Zener Diodes Applications

• Precision voltage reference applications
• Circuits requiring low operating current

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The standard designation indicates lead-free compliance. Confirm package type and electrical tolerances match design requirements before procurement. Ensure storage conditions align with the specified temperature limits to maintain component integrity.

Single Zener Diodes Selection Notes

Select this component when a precise 3.9 V reference is required in a minimal footprint. Consider the 1600 Ω impedance limit for dynamic load variations. Evaluate the thermal resistance of 500 °C/W for heat management in dense layouts. Verify that the 250 µA test current aligns with the target circuit's biasing capabilities.

Single Zener Diodes Part Context

This part belongs to the CMOZ1L8 Series, which covers Zener voltages from 1.8 V to 47 V. All devices in this series share the same SOD-523 mechanical outline and general low-level performance profile. The series is designed to provide consistent regulatory performance across a wide voltage spectrum while maintaining small physical dimensions.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 3.9 V nominal voltage, SOD-523 package, and 250 mW power rating. Verify that alternative components meet the 5% tolerance and impedance specifications. Cross-reference marking codes if visual identification is required for assembly verification.
